It is true that all atoms have moving electric charges, not all materials are magnetic.

The presence of moving electric charges alone does not guarantee that a material will exhibit magnetic properties. Several factors contribute to whether a material is magnetic or not:

1. Electron configuration: The arrangement of electrons within an atom plays a crucial role in determining magnetic properties. In materials with paired electrons and a completely filled electron shell, the magnetic effects of individual electrons cancel out, resulting in a lack of overall magnetic behavior.

2. Magnetic domains: Magnetic materials typically consist of microscopic regions called magnetic domains, where groups of atoms align their magnetic moments in the same direction. In non-magnetic materials, these magnetic domains are randomly oriented, resulting in a net magnetic moment of zero.

3. External magnetic field: Some materials, known as ferromagnetic materials, can be magnetized by an external magnetic field. When subjected to an external field, the magnetic domains align, resulting in a macroscopic magnetic effect. However, for non-magnetic materials, the alignment of magnetic domains does not occur or is very weak.

4. Magnetic properties of electrons: The behavior of electrons in different atomic orbitals and energy levels can significantly influence the magnetic properties of materials. In some materials, the electrons' spin and orbital angular momentum can align in a way that creates a net magnetic moment, making them magnetic.

Therefore, while all atoms have moving electric charges, the specific arrangement and behavior of these charges, as well as the presence of aligned magnetic domains, determine whether a material exhibits magnetic properties.

The maximum velocity and acceleration of the eardrum are greater for high-frequency sound compared to low-frequency sounds.The wavelength of a sound wave is inversely proportional to its frequency. The maximum acceleration is approximately 1.59×10⁻⁴ m/s².  Amplitude is 1.0×10⁻⁸.

(a) For a given vibration amplitude, the maximum velocity and acceleration of the eardrum are greater for high-frequency sound compared to low-frequency sounds.

The explanation for this can be found in the relationship between frequency and wavelength. The wavelength of a sound wave is inversely proportional to its frequency. The wavelengths of higher-frequency noises are shorter than those of lower-frequency sounds.

It oscillates when the eardrum vibrates in response to a sound wave. How swiftly the eardrum moves determines its velocity, and the acceleration is proportional to how rapidly the velocity varies.

In the case of high-frequency sound waves with shorter wavelengths, the eardrum must resonate more quickly in order to keep up with the wave's compressed and rarified regions. This results in increased speeds and accelerations of the eardrum.

Low-frequency sound waves with longer wavelengths, on the other hand, cause the eardrum to resonate more slowly, resulting in lower velocities and accelerations.

(b) To find the maximum velocity and acceleration of the eardrum for vibrations of amplitude 1.0×10⁻⁸m at a frequency of 20.0 Hz:

The maximum velocity (v_max) of the eardrum can be calculated using the formula:

v[tex]_{max}[/tex] = 2πfA

Substituting the given values:

v[tex]_{max}[/tex] = 2π × 20.0 Hz × 1.0×10⁻⁸ m

Calculating the value:

v[tex]_{max}[/tex] = 1.26×10⁻⁶ m/s (rounded to two significant figures)

The maximum acceleration (a[tex]_{max}[/tex]) of the eardrum can be found using the relationship: a[tex]_{max}[/tex] = (2πf)²A

Substituting the given values:

a[tex]_{max}[/tex] = (2π × 20.0 Hz)² × 1.0×10⁻⁸ m

Calculating the value:

a[tex]_{max}[/tex] = 1.59×10⁻⁴ m/s² (rounded to two significant figures)

Therefore, for vibrations of amplitude 1.0×10⁻⁸ m at a frequency of 20.0 Hz, the maximum velocity of the eardrum is approximately 1.26×10⁻⁶m/s, and the maximum acceleration is approximately 1.59×10⁻⁴ m/s².

(c) To repeat the calculation for the same amplitude (1.0×10⁻⁸ m) but a frequency of 20.0 kHz:

Using the same formulas as before, we can calculate the maximum velocity and acceleration:

v[tex]_{max}[/tex] = 2πfA

v[tex]_{max}[/tex] = 2π × (20.0 × 10³ Hz) × 1.0×10⁻³ m

Calculating the value:

v[tex]_{max}[/tex] = 1.26 m/s (rounded to two significant figures)

a[tex]_{max}[/tex] = (2πf)²A

a[tex]_{max}[/tex] = (2π × (20.0 × 10³ Hz))² × 1.0×10⁻⁸ m

Calculating the value:

a[tex]_{max}[/tex] = 1.59 × 10⁶m/s² (rounded to two significant figures)

The boat will be approximately 50.2 meters east from its starting point.

To find the distance east of the boat from its starting point, we need to consider the combined effect of the river's flow and the boat's velocity. The river's width and speed, along with the boat's velocity relative to the water, will influence the boat's path.

First, we calculate the time it takes for the boat to cross the river. Since the river is 60.0 meters wide and the boat's velocity relative to the water is 4.0 m/s, the boat will take 60.0 m / 4.0 m/s = 15.0 seconds to cross the river.

Next, we determine the displacement caused by the river's flow during the time it takes for the boat to cross. The river flows due east with a speed of 3.00 m/s, so the displacement is given by 15.0 seconds * 3.00 m/s = 45.0 meters.

Finally, we find the eastward distance traveled by the boat. Since the boat's displacement due north is equal to the river's displacement, and the boat's displacement due east is its actual displacement, we use the Pythagorean theorem. The boat's eastward distance is then √[(60.0 m)²- (45.0 m)²] = 50.2 meters.

The resting membrane potential of a neuron used in an experiment typically ranges between -60 to -70 millivolts (mV).

The resting membrane potential refers to the electrical potential difference across the cell membrane of a neuron when it is at rest, meaning it is not actively sending or receiving signals. It is primarily maintained by the concentration gradients of ions, such as sodium (Na+), potassium (K+), and chloride (Cl-), across the membrane.

In a typical neuron, the resting membrane potential is mainly determined by the selective permeability of the cell membrane to potassium ions. Due to the presence of potassium leak channels, there is a higher concentration of potassium ions inside the cell compared to the outside. This creates an electrical imbalance, resulting in a negative charge inside the neuron relative to the outside.

Although the specific value of the resting membrane potential can vary depending on factors such as the type of neuron and experimental conditions, the range of -60 to -70 mV is commonly observed and used as a reference in neuroscience experiments.

Option b is correct. The mass of melted ice due to the temperature increase of the plate at the bottom of the incline is 0.04 kg or 40 g (approx.)

The kinetic energy of the ice plate is converted into the latent heat of fusion, melting ice when the ice plate moves down the inclined surface. The latent heat of fusion is the amount of heat energy required to convert one unit of mass from a solid state into a liquid state without altering its temperature.

It means the temperature of the ice plate remains constant when it melts. To solve the given problem, use the principle of conservation of mechanical energy, which states that the total mechanical energy of a system remains constant if no external forces act on it. The initial potential energy of the ice plate is mgh where m = [tex]0.2 kg, g = 9.8 m/s^2[/tex], and [tex]h = 15 sin 30^0 = 7.5 m[/tex]

Initial potential energy = mgh = 0.2 × 9.8 × 7.5 = 14.7 J

Let the melted ice mass be m' in kg. The final potential energy of the ice plate is 0 because it reaches the bottom of the inclined surface. The final kinetic energy of the ice plate is converted into the latent heat of fusion to melt the ice, given by:

The initial magnetic field (B) is approximately 2.89 T.

The current in the loop when the plane makes an angle of 37 degrees with the magnetic field is approximately 37.68 mA.

The direction of the induced current is counterclockwise.

We know that the rate of change of magnetic flux (dΦ/dt) is equal to the electromotive force (emf) induced in the coil. Since the current is constant, the induced emf is given by Faraday's law as emf = -N(dΦ/dt), where N is the number of turns in the coil. In this case, N = 60. Given that the rate of change of magnetic field (dB/dt) is -2.89 T/5.2 s, we can find the initial magnetic field B by rearranging the equation: B = -(emf) / (N(dΦ/dt)) = -[(60)(-2.89 T/5.2 s)] = 2.89 T. Therefore, the initial magnetic field is approximately 2.89 T.

When the plane of the coil makes an angle with the magnetic field, the magnetic flux through the coil changes. The induced emf is still given by Faraday's law, but we need to consider the component of the magnetic field perpendicular to the plane of the coil. In this case, the perpendicular component is B⊥ = Bsinθ, where θ is the angle between the plane of the coil and the magnetic field. Given that B = 2.89 T and θ = 37 degrees, the perpendicular magnetic field component is B⊥ = 2.89 T × sin(37°) = 1.73 T.

Using Faraday's law and rearranging the equation, we can solve for the induced current (I) as I = -(emf) / (N(dΦ/dt)) = -[(60)(-1.73 T/5.2 s)] = 37.68 mA. Thus, the current in the loop when the plane makes an angle of 37 degrees with the magnetic field is approximately 37.68 mA.

To determine the direction of the induced current, we can use Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic flux. When the plane of the coil makes an angle with the magnetic field, the magnetic flux through the coil decreases. According to Lenz's law, the induced current will flow in a direction to create a magnetic field that opposes the decreasing flux.

In this case, as the magnetic field decreases, the induced current will flow in a counterclockwise direction. Hence, the direction of the induced current is counterclockwise.

To solve for the speed and height of a bullet fired from a toy gun, the following data is provided:

Rest length of the spring (L1) = 125 mm

Compressed length of the spring (L2) = 25 mm

Extension of spring after firing = 75 mm

Spring force before firing = 34 N

Mass of bullet (m) = 33 g = 0.033 kg

Gravity constant (g) = 9.81 m/s²

To determine the speed (v) of the bullet, we will use the conservation of energy principle.

Conservation of Energy Law states that "energy cannot be created or destroyed, only transferred or transformed from one form to another."

The total energy before and after firing is equal. Thus, the spring potential energy (U1) before firing is equal to the kinetic energy (K) of the bullet when it leaves the gun.U1 = K1Where, U1 = (1/2)kL1², L1 = 0.125 m, L2 = 0.025 m, and k is the spring constant

k = F/L1-L2Where, F is the spring force, and L1-L2 is the spring compression length

k = 34 / (0.125 - 0.025)

   = 340 N/mU1

   = (1/2)kL1²

   = 14.875 J

The kinetic energy of the bullet (K) is given as:K = (1/2)mv²...equation (1)

Where, m is the mass of the bullet, and v is its velocity.

Substituting the given values in equation (1), we get:

14.875 = (1/2) x 0.033 x v²

v = √(14.875 / 0.0165) = 25.64 m/s

Therefore, the speed of the bullet is 25.64 m/s.

Now, to determine the height (H) to which the bullet rises,

we can use the Kinematic equation.v² - u² = 2gh

Where, u is the initial velocity, which is zero in this case.

Substituting the values, we get:

25.64² = 2 x 9.81 x H2

H = (25.64² / 19.62) m

H = 33.5 m

Therefore, The bullet ascends 33.5 metres in height.

The velocity of the 0.100 kg ball after the collision is -4.3 m/s (in the -x direction) since the negative sign indicates the opposite direction of the initial velocity.

To solve this problem, we can apply the principle of conservation of momentum. In an elastic collision, the total momentum before the collision is equal to the total momentum after the collision.

(0.100 kg * 4.30 m/s) + (0.300 kg * 0 m/s) = (0.100 kg * v₁') + (0.300 kg * v₂')

0.43 kg·m/s = 0.100 kg·v₁' + 0.300 kg·v₂'

Since the 0.300 kg ball is at rest, v₂' = 0, and we can simplify the equation:

0.43 kg·m/s = 0.100 kg·v₁'

Solving for v₁':

v₁' = (0.43 kg·m/s) / (0.100 kg)

v₁' ≈ 4.3 m/s

Therefore, the velocity of the 0.100 kg ball after the collision is -4.3 m/s (in the -x direction) since the negative sign indicates the opposite direction of the initial velocity.

The force of the air on the parachute is 102.375 N, directed upward.

To calculate the force of the air on the parachute, we can use Newton's second law, which states that force is equal to mass multiplied by acceleration. In this case, the acceleration is the instantaneous upward acceleration experienced by the parachutist.

Given that the mass of the parachutist is 97.5 kg and the upward acceleration is 1.05 m/s², we can calculate the force as follows:

Force = mass × acceleration

Force = 97.5 kg × 1.05 m/s²

Force = 102.375 N

Therefore, the force of the air on the parachute is 102.375 N, directed upward.

For concave spherical mirror ,the image is real as it is formed on the other side of the mirror.

For a convex mirror, the image is virtual as it is formed on the same side of the mirror.

a) Object distance u = -30 cm

Focal length of the mirror f = -10 cm .

The mirror is concave, Hence the focal length is negative.

Using the mirror formula,

1/f = 1/u + 1/v

= 1/-10 + 1/-30 = -1/5.

The image distance v is,

1/f = 1/u + 1/v

1/v = 1/f - 1/u= -1/5.

The magnification is,

M = v/u = (-1/5)/(-30) = 1/150.

The negative value of magnification indicates that the image is inverted.The magnification value is less than one, which indicates that the image is smaller in size than the object.The image is real as it is formed on the other side of the mirror. Thus, the image distance is negative.

The shortest distance between a node and an antinode is 1.67 cm. The correct option is O D = 16.67 cm.

To determine the shortest distance between a node and an antinode in a standing wave, we need to analyze the given wave function y(x,t) = 0.1 sin(3πx) cos(50πt).

In a standing wave, nodes are points of zero displacement, while antinodes are points of maximum displacement. By examining the form of the wave function, we can identify the locations of nodes and antinodes.

For the given wave function, the sin(3πx) term represents the spatial variation of the wave, while the cos(50πt) term represents the temporal variation.

Since the sin function has nodes at integer multiples of π, and the cos function has a maximum value of 1 at t = 0, we can conclude that the nodes occur at x = 0, x = λ/6, x = 2λ/6, etc., where λ is the wavelength.

The shortest distance between a node and an antinode occurs when we move from a node to the adjacent antinode. This distance is equal to one-quarter of the wavelength (λ/4). Therefore, we need to determine the wavelength (λ) of the wave.

The spatial variation sin(3πx) suggests that the wavelength can be calculated as λ = 2π/k, where k is the wave number. In this case, k = 3π, so λ = 2π/(3π) = 2/3 meters.

Now, we can determine the shortest distance between a node and an antinode by taking one-quarter of the wavelength: (2/3)/4 = 2/12 = 1/6 meters = 0.1667 meters = 16.67 cm.

The form of energy stored in a stretched spring is elastic potential energy. When a spring is stretched or compressed, it possesses potential energy due to the deformation of its structure.

This potential energy is called elastic potential energy because it is associated with the elasticity of the spring.

As the spring is stretched, work is done to overcome the forces within the spring that resist the change in its length. This work is converted into potential energy, which is stored in the spring. The amount of potential energy stored in the spring is directly proportional to the amount by which it is stretched or compressed.

When two forces are simultaneously applied to a spring in opposite directions, it may result in elongation or contraction of the spring, depending on the magnitude and direction of the forces. If the applied forces are strong enough to overcome the spring's elasticity, the spring will undergo deformation and exhibit elongation or contraction. This deformation is a manifestation of the stored elastic potential energy being converted into mechanical energy.

Shear, bending, and intermolecular binding energy are not directly related to the stretching of a spring.

The loss of static electricity as electric charges move from one object to another is referred to as "electrostatic discharge / option c: static electricity". It occurs when the accumulated electric charges neutralize, resulting in a transfer of charge and the dissipation of static electricity.

The phenomenon of electrostatic discharge involves the movement of electric charges from one object to another, leading to the loss of static electricity. When two objects have different electric potentials or charges, they can exchange electrons through a conductive pathway,

allowing the charges to equalize. This process occurs due to the repulsion or attraction of electric charges, which creates an electric field and electric force between the objects.

(a) The electric field is a region surrounding an electric charge or charged object that exerts a force on other charges within its vicinity. It plays a role in the transfer of electric charges during electrostatic discharge.

(b) The electric force refers to the attraction or repulsion between electric charges, resulting in the movement of charges when objects come into contact or close proximity. It is responsible for driving the transfer of charges during electrostatic discharge.

(c) Static electricity refers to the accumulation of electric charges on an object or surface, resulting in an imbalance of charges. Electrostatic discharge occurs to eliminate this static electricity by allowing charges to move from areas of higher concentration to areas of lower concentration.

(d) Electrostatic refers to phenomena and properties related to stationary electric charges. Electrostatic discharge is an example of the behavior of electric charges in static situations and their subsequent discharge.

Doubling the length of the blades of a wind turbine would increase the torque on the turbine.

When the length of the blades of a wind turbine is doubled, it effectively increases the surface area exposed to the wind. As a result, more wind energy is captured and transferred to the rotor, leading to an increase in torque on the turbine. This increase in torque is due to the principles of aerodynamics and the way wind turbines generate power.

Wind turbines work by harnessing the kinetic energy of the wind and converting it into mechanical energy, which is then transformed into electrical energy. The blades of a wind turbine are designed to capture as much wind energy as possible. When the wind blows, it exerts a force on the blades, causing them to rotate. The force acting on the blades is directly proportional to the area they sweep through and the speed of the wind.

By doubling the length of the blades, the swept area increases. This means that the blades intercept a larger volume of air as they rotate, resulting in a higher force being exerted on the turbine. Since torque is the rotational equivalent of force, the increased force applied to the blades leads to an increase in torque on the turbine.

It's important to note that other factors, such as wind speed and blade design, can also influence the torque on a wind turbine. However, assuming all other factors remain constant, doubling the length of the blades will result in a proportional increase in torque.

An object can be in a state of zero net force but still not in equilibrium due to the presence of other factors such as unbalanced torques, internal forces, or unstable configurations. These factors can cause the object to experience rotational or translational motion, leading to a lack of equilibrium.

Unbalanced Torques, Even if the net force on an object is zero, it may experience unbalanced torques. Torques can result from external forces applied at different distances from the pivot point or from uneven distribution of mass. This can cause the object to rotate or spin, indicating a lack of equilibrium.

Internal Forces, In some cases, an object may experience internal forces that prevent it from being in equilibrium, even if the net external force is zero. Internal forces can arise from structural constraints, elasticity, or tension within the object itself. These forces can cause deformations or internal motion, indicating a lack of equilibrium.

Unstable Configurations, Objects in unstable configurations can be in a state of zero net force but are not in equilibrium. For example, a pencil balanced on its tip can have a net force of zero but is in an unstable equilibrium. A slight disturbance can cause the object to move, indicating a lack of equilibrium.

Therefore, an object can be in a state of zero net force but not in equilibrium due to unbalanced torques, internal forces, or unstable configurations, which can lead to rotational or translational motion.

The refracted angle when light is refracted from water into a quartz crystal with an incident angle of 30^∘ is approximately 26.58 ^∘(Option C).

When light passes from one medium to another, it undergoes refraction, which causes a change in direction. The relationship between the incident angle and the refracted angle (θ1) and the refracted angle (θ2)  is given by Snell's law: sinθ1/sinθ2=n2/n1. where n1 and n2 are the refractive indices of the two media. In this case, the incident medium is water and the refractive medium is quartz crystal. The refractive index of water is approximately 1.33, and the refractive index of quartz crystal is around 1.46. Plugging these values into Snell's law and solving we get, (θ2)=26.58^ ∘  which represents the approximate refracted angle when light passes from water into a quartz crystal with an incident angle of 30^∘.
