An electric fan is made up of several simple machines. Tell where you would find an inclined plane on a fan. Also, tell where you would find a wheel and axle.

Answers

Answer 1

The fan blades or propellers of an electric fan are examples of an inclined plane. The blades' frequently curved or angled shapes provide an inclined surface that effectively moves air.

Air is forced along the incline as the blades spin, creating airflow. An electric fan's motor assembly includes a wheel and an axle. The rotor, a revolving component, is connected to the motor's central shaft, also known as the axle.

Usually cylindrical in form, the rotor serves as the wheel. The motor spins around the fixed axle when electrical power is applied, which causes the fan blades to move and the air to circulate.

Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 4 m/s2.
Reference: Ref 2-11


Which statement accurately describes the motion of the particle?
Group of answer choices

The final velocity of the particle will be proportional to the distance that the particle covers.

The particle travels 4 meters during the first second only.

The speed of the particle increases by 4 m/s during each second.

The acceleration of the particle increases by 4 m/s2 during each second.

The particle travels 4 meters during each second.

Answers

The correct statement is that the speed of the particle increases by 4 m/s during each second.

The correct answer is Option C.

The statement that accurately describes the motion of the particle is:

"The speed of the particle increases by 4 m/s during each second."

Given that the particle is accelerated at a constant rate of 4 m/s², its speed (velocity magnitude) increases by 4 m/s every second. This means that after the first second, the particle will have a speed of 4 m/s. After the second second, the speed will be 8 m/s, and so on. The rate of increase in speed is constant at 4 m/s per second.

The other statements are not accurate:

The final velocity of the particle will not be proportional to the distance covered. The final velocity depends on the time of acceleration, not the distance covered.

The particle does not necessarily travel exactly 4 meters during the first second or each second. The distance traveled depends on the initial conditions, such as the starting position and time of observation.

The acceleration of the particle remains constant at 4 m/s². It does not increase by 4 m/s² during each second.

The correct answer is Option C.

Q14. A particle starts from rest and moves with a constant acceleration of 0. Sms-s. What is the distance covered by the particle in 10s. ​

Answers

The distance covered by the particle in 10 seconds is 0 meters.

Given that the particle starts from rest and moves with a constant acceleration of 0. Sms-s, we can use the equation of motion to determine the distance covered by the particle in 10 seconds.

The equation for distance covered (s) by an object with constant acceleration can be expressed as:

s = ut + (1/2)at²,

where u is the initial velocity (which is zero in this case), a is the constant acceleration, and t is the time taken.

In this scenario, the particle starts from rest, so its initial velocity (u) is 0 m/s. The acceleration (a) is given as 0 m/s². The time (t) is 10 seconds.

Substituting the given values into the equation, we have:

s = 0(10) + (1/2)(0)(10)² = 0 + 0 = 0.

The Following potentials were measured in a circuit: i) ii) iii) E is at ground potential and A is +100 volts wrt ground D is +50 volts wrt E C is +15 volts wrt D A is +20 volts wrt B What are the potentials at B, C and D with respect to ground. What is the potential at C wrt B and D. What is the potential at B wrt E.​

Answers

Potential at C with respect to B is +65 volts (C with respect to ground) - +80 volts (B with respect to ground) is -15 volts with respect to B.

How to calculate the value

To find the potentials at B, C, and D with respect to the ground:

Potential at B with respect to ground:

Since A is at +100 volts with respect to ground and +20 volts with respect to B, we can deduce that B is 100 - 20 = +80 volts with respect to ground.

Potential at B = +80 volts with respect to ground.

Potential at C with respect to ground:

C is at +15 volts with respect to D, and D is at +50 volts with respect to E. Since E is at ground potential (0 volts), we can calculate the potential at C with respect to ground by adding the potentials:

Potential at C = +50 volts (D with respect to E) + 15 volts (C with respect to D) = +65 volts with respect to ground.

Potential at D with respect to ground:

D is at +50 volts with respect to E, and E is at ground potential (0 volts). Therefore, the potential at D with respect to ground is:

Potential at D = +50 volts (D with respect to E) + 0 volts (E with respect to ground) = +50 volts with respect to ground.

Now, let's calculate the potential at C with respect to B and D:

Potential at C with respect to B:

We know that A is at +20 volts with respect to B. Combining this information with the potential at A (+100 volts with respect to ground), we can determine the potential at B with respect to ground:

Potential at B = +100 volts with respect to ground - +20 volts (A with respect to B) = +80 volts with respect to ground.

Since we already calculated the potential at C with respect to ground as +65 volts, we can find the potential at C with respect to B:

Potential at C with respect to B = +65 volts (C with respect to ground) - +80 volts (B with respect to ground) = -15 volts with respect to B.

The air temperature is 25∘C, and an air column carries a standing sound wave at a frequency of 340Hz . What is the length of the air column, which is closed at one end, if you want to hear the third harmonic?

Answers

To hear the third harmonic of a standing sound wave at a frequency of 340 Hz, the length of the closed air column should be approximately 4.55 meters.

The formula for the length of a closed-closed air column in resonance can be used to calculate the length of the air column necessary to hear the third harmonic of a standing sound wave:

L = (4/n) * v/f

Where L represents the height of the air column, n the harmonic number, v the air speed, and f the desired harmonic frequency.

Given:

25°C (298 K) is the ambient temperature.

The required harmonic's (f) frequency is 340 Hz.

(n) = 3 for the harmonic number

At room temperature, the speed of sound in air can be roughly calculated to be 343 m/s. It must be adjusted for the current air temperature because the speed of sound is temperature-dependent.

Using the equation: v = 331.5 + 0.6 * T, where T is the Celsius value of the air temperature.

If T = 25 °C is used in the formula:

v = 331.5 + 0.6 * 25 v ≈ 331.5 + 15 v ≈ 346.5 m/s

We can now determine how long the air column is:

Answers

The acceleration of the car is 1 m/s².

As the car is at rest in the beginning,

the initial velocity of the car = 0 m/s

Final velocity after 20 seconds = 20 m/s         (given)

We know that,

Acceleration of an object = Rate of change of the velocity of the object

Now,

change in velocity of the car = final velocity of the car - initial velocity of                      the car

                                                = 20 m/s - 0 m/s

                                                = 20 m/s

Answers

Andrea's displacement after 137 seconds is 824.74 meters to the east. This means that she has moved a distance of 824.74 meters in the eastward direction from her starting position.

Andrea's displacement after 137 seconds can be calculated by multiplying her average speed by the time traveled. Since she is running to the east, her displacement will be positive.

Displacement is given by the formula: Displacement = Average speed × Time

Substituting the given values, we have: Displacement = 6.02 m/s × 137 s

Calculating this expression, we find: Displacement = 824.74 m Displacement is a vector quantity that not only represents the magnitude (distance) but also the direction of motion. In this case, Andrea's displacement is positive because she ran to the east, indicating a displacement in the positive x-direction.

Find distance between two object of radius 6 cm and 2 cm

Answers

The distance between two objects of radius 6 cm and 2 cm is zero

To find the distance between two objects with radii of 6 cm and 2 cm, we need to consider the center-to-center distance between the objects and subtract the sum of their radii.

Let's denote the radii of the objects as r1 = 6 cm and r2 = 2 cm.

The distance between the centers of the objects can be represented as d = r1 + r2. Adding the radii ensures that we account for the space occupied by both objects.

Substituting the values, we have d = 6 cm + 2 cm = 8 cm.

Now, to find the actual distance between the objects, we subtract the sum of their radii from the center-to-center distance:

Distance = d - (r1 + r2) = 8 cm - (6 cm + 2 cm) = 8 cm - 8 cm = 0 cm.

The resulting distance is 0 cm, indicating that the objects are in direct contact with each other. This means that their surfaces are touching. When the distance between two objects is zero, it implies that they are overlapping or in physical contact. In this case, since the distance is equal to 0 cm, the two objects are touching each other, with their surfaces coming into contact.

ANSWERED: -6.21 N

Answers

To calculate the net force on particle q₁, we can use Coulomb's law to find the magnitude of the force between q₁ and q₂, as well as the force between q₁ and q₃. The force between two charges is given by:

F = k * (q₁ * q₂) / r²

where k is Coulomb's constant, q₁ and q₂ are the charges, and r is the distance between the charges.

Using this formula, we can find that the magnitude of the force between q₁ and q₂ is:

F₁₂ = k * (q₁ * q₂) / r₁₂² = (9 x 10⁹ N m²/C²) * ((-2.35 x 10⁻⁶ C)² / (0.100 m)²) = 5.54 x 10⁻⁴ N

Similarly, the magnitude of the force between q₁ and q₃ is:

F₁₃ = k * (q₁ * q₃) / r₁₃² = (9 x 10⁹ N m²/C²) * ((-2.35 x 10⁻⁶ C)² / (0.100 m)²) = 5.54 x 10⁻⁴ N

Since the charges q₂ and q₃ are equal in magnitude and opposite in sign, they will produce equal and opposite forces on q₁, which cancel each other out. Therefore, the net force on q₁ is:

F_net = F₁₂ + F₁₃ = (5.54 x 10⁻⁴ N) + (5.54 x 10⁻⁴ N) = 1.11 x 10⁻³ N

The direction of this force will be towards q₂, since the force between q₁ and q₂ is attractive. Therefore, the correct answer to the question is that the net force on particle q₁ is -1.11 x 10⁻³ N.

Q is the heat energy absorbed by the water,

m is the mass of the water,

s is the specific heat capacity of water,

dt is the change in temperature.

Given:

Q = 3.6 x 10^5 J

m = 2 kg

s= 4,186 J/kg°C (specific heat capacity of water)

Initial temperature, T_initial = 40°C

Rearranging the formula, we have:

dt = Q / (ms)

Substituting the given values:

dt = (3.6 x 10^5 J) / (2 kg * 4,186 J/kg°C)

Calculating:

dt ≈ 43.13°C

To find the final temperature, we add the change in temperature to the initial temperature:

Final temperature = T_initial + dT(above formed temp)

Final temperature = 40°C + 43.13°C

Final temperature = 83.13°C

Therefore, the correct final temperature of the water is approximately 83.13.

To determine the unit vector using the components and magnitude of a vector, hence option A is correct.

We can use the following relationship:

Let's consider a force vector F with components Fx, Fy, and Fz, and a magnitude of |F|. The unit vector u in the direction of F can be expressed as:

u = (Fx/|F|) i + (Fy/|F|) j + (Fz/|F|) k

Here, i, j, and k represent the unit vectors in the x, y, and z directions, respectively.

This relationship ensures that the resulting vector u has a magnitude of 1, representing a unit vector.

a healthy person has a body temperature of 37 degree celsius. if they jump into an ice bath after sports training their temperature only decreases slowly. how can you explain this when a lump of metal at 37 celsius degree placed in the same ice bath cools down to 0 celsius degree in only a couple of minutes

Answers

The difference in cooling rates between a healthy person and a lump of metal when placed in an ice bath can be attributed to several factors:

1. Heat Capacity: The heat capacity of the human body is much higher than that of a small lump of metal. The human body has a large mass and contains a significant amount of water, which has a high heat capacity. This means that it requires more energy to change the temperature of the body compared to a small metal object. As a result, the body cools down more slowly in the ice bath.

2. Insulation: The human body is well-insulated with layers of skin, fat, and clothing. These layers act as thermal barriers and slow down the transfer of heat between the body and the surroundings. On the other hand, a small metal object does not have any significant insulation, allowing heat to transfer more rapidly to the colder environment.

3. Biological Regulation: The human body has mechanisms to regulate its temperature, such as vasoconstriction (narrowing of blood vessels) and shivering, which help generate heat and maintain core temperature. These regulatory processes help to slow down the cooling process and preserve the body's temperature within a narrow range.

4. Surface Area-to-Volume Ratio: The surface area-to-volume ratio is higher for a small lump of metal compared to a human body. A higher surface area facilitates faster heat transfer. Since the metal object has a relatively larger surface area compared to its volume, it cools down more quickly in the ice bath.

Overall, the combination of the human body's higher heat capacity, insulation, biological regulation, and lower surface area-to-volume ratio compared to a small metal object contributes to the slower cooling rate when immersed in an ice bath.

Calculate the depth below the surface of ocean water where the total pressure is 1.105-108 Pa. Density of ocean water is 1.025 g/cm³.​

Answers

The depth below the surface of the ocean where the total pressure is 1.105-108 Pa is 1.076 × 10⁶ meters.

Understanding the Depth and Density of Ocean water

Using hydrostatic pressure equation, which relates pressure, density, and depth in a fluid:

P = P₀ + ρgh

Where:

P is the total pressure at depth h,

P₀ is the atmospheric pressure (assuming it is negligible),

ρ is the density of the fluid (ocean water),

g is the acceleration due to gravity.

Given:

ρ = 1.025 g/cm³ * (1000 kg/1 g) * (1 m/100 cm)³

  = 1025 kg/m³

g = 9.8 m/s².

Now, we can rearrange the equation to solve for the depth h:

h = (P - P₀) / (ρg)

Substituting the given values:

h = (1.105 × 10⁸ Pa) / (1025 kg/m³ * 9.8 m/s²)

Calculating this expression:

h ≈ 1.105 × 10⁸ Pa / (1025 kg/m³ * 9.8 m/s²)

 ≈ 1.105 × 10⁸ m²/(kg·s²) / (1025 kg/m³ * 9.8 m/s²)

 ≈ 1.105 × 10⁸ m / (1025 * 9.8) m

 ≈ 1.076 × 10⁶ m

Therefore, the depth below the surface of the ocean where the total pressure is 1.105-108 Pa is approximately 1.076 × 10⁶ meters.
