1.43 Nm is the torque needed to accelerate the wheel from rest to 1950 rpm in 5.00 s. take into report a frictional torque that has been calculated to slow down the wheel from 1500 rpm to rest in 55.0 s

Speed of wheel = 1950 rpm

Time is taken to accelerate =  5.00 s

Speed of wheel to slowdown =  1500 rpm

Time taken to rest =55.0 s

To calculate the torque needed to accelerate the wheel:

τ = Iα

To calculate the angular acceleration:

α = Δω / Δt

the change in angular velocity is calculated by using the formula:

Δω = ωf - ωi

At initial the velocity is Zero.

ωf = 1950 rpm

ωf = 1950 rev/min = 1950/60 rad/s

ωf = 32.5 rad/s

The angular acceleration is:

α = Δω / Δt = (32.5 rad/s)  ÷ 5.00

α =  6.50 rad/s^2

To calculate the moment of inertia,

I = (1/2)MR^2

The final speed of the wheel is 1950 rpm, which corresponds to a linear speed of:

v = ωf R = (1950/60 rev/s) ÷ (2π R)

v  = 204.2 R m/s

To calculate the circumference,

C = 41.67 * (2π R)

C = 83.34 π R

The linear distance traveled during this time is:

d = v t = (204.2 R m/s) (55.0 s)

d = 11,231 R m

to calculate the radius of wheels:

83.34 π R = 11,231 R m

R = 42.7 m

V = π R^2 h

V =[tex]3.14 * (0.427 m)^2 *(0.02 m)[/tex]

V = 0.000574 m

The mass is:

M = V ρ = [tex](0.000574 m^3) (7.8 g/cm^3) (1000 cm^3/m^3)[/tex]

M = 4.49 kg

Now we can calculate the torque needed to accelerate the wheel using the formula:

τ = Iα = (1/2)MR^2 α

τ = [tex](1/2) (4.49 kg) (0.427 m)^2 (6.50 rad/s^2)[/tex]

τ = 1.43 Nm

The blue car has experienced a larger change in velocity compared to the red car. This is because the change in velocity depends on the rate of acceleration, not just the speed of the car.

Velocity is a vector quantity that includes both speed and direction, so a change in velocity can occur if there is a change in speed, direction, or both. In this case, assuming that both cars are traveling at a constant speed around the curve, the car that experiences a larger change in velocity is the blue car. This is because the blue car is traveling at a slower speed than the red car, so it must undergo a greater change in velocity to stay on the same curve as the faster-moving red car.

Longitudinal waves oscillate in the same direction as the wave propagation, while transverse waves oscillate perpendicular to the direction of wave propagation, and factors that affect propagation of sound waves include medium, frequency, humidity, and obstacles in the path.

Longitudinal waves are waves that oscillate in the same direction as the direction of wave propagation. An example of a longitudinal wave is a sound wave traveling through air. As sound waves travel through the air, the air particles oscillate back and forth along the same direction as the wave propagation. This creates regions of high pressure (compressions) and low pressure (rarefactions) as the wave moves through the air.

The propagation of sound waves is affected by several factors. One of the most important factors is the medium through which the sound wave travels. Sound waves can travel through solids, liquids, and gases, but they propagate differently in each medium due to differences in the medium's properties, such as density and elasticity.

Other factors that affect the propagation of sound waves include the frequency and amplitude of the wave. Higher frequency waves tend to travel further, while higher amplitude waves tend to travel shorter distances. Additionally, the temperature and humidity of the medium can also affect the propagation of sound waves. In general, sound waves travel faster in warmer and more humid environments.

It takes approximately 24 hours and 50 minutes for a diurnal tide to complete a full cycle and return to the same phase.

The equilibrium model of the timing of tides predicts that the time between successive high tides for a diurnal tide should be approximately 24 hours and 50 minutes. This is based on the idea that the tides are primarily caused by the gravitational forces of the Moon and Sun on the Earth's oceans.

For a diurnal tide, there is only one high tide and one low tide per day. This is because the Moon and Sun have a combined effect on the tides, and their gravitational forces act in such a way that they cancel out the effects of each other, resulting in a single high tide and a single low tide.

The Moon takes approximately 24 hours and 50 minutes to return to the same position relative to the Earth, and it is this alignment of the gravitational forces of the Moon and Sun that causes the tides.

The distance traveled by Dheepthi from point A to B is 29.5m.

To find the distance AB, we need to use Pythagoras' theorem, which states that the square of the hypotenuse (the longest side) of a right triangle is equal to the sum of the squares of the other two sides.

In this case, we can break down Dheepthi's journey into a series of right triangles.

First, she walks 4m in the south direction from point A. Then, she turns right and walks 5m, forming a right triangle with legs of 4m and 5m.

Using Pythagoras' theorem, we can calculate the hypotenuse (her distance from point A) to be 6.4m.

Next, she turns left and walks 3m, forming another right triangle with legs of 1.6m (the remainder of her distance south) and 3m. Using Pythagoras' theorem again, we can calculate the hypotenuse of this triangle to be 3.4m.

Then, she turns right and walks 4m, forming a right triangle with legs of 1.6m and 4m. The hypotenuse of this triangle is 4.2m.

Finally, she turns right again and walks 15m, forming a right triangle with legs of 4.2m and 15m. The hypotenuse of this triangle is 15.5m.

Adding up all of these distances, we get a total distance of 6.4m + 3.4m + 4.2m + 15.5m = 29.5m. Therefore, the distance AB is 29.5m.

The main reason for this is the lack of atmosphere on the moon. On Earth, the atmosphere absorbs some of the energy from the impact, reducing the severity of the crater. Additionally, erosion from wind and water can also affect the appearance of the crater on Earth. On the moon, however, there is no atmosphere to absorb the energy from the impact, so the crater will retain its original shape and size for a longer period of time.

The radial velocity technique is effective at finding planets that are massive and close to their host stars. This method has been particularly successful in detecting gas giant planets, with masses similar to or greater than Jupiter.

The radial velocity technique is effective at finding planets by measuring the small wobbles in a star's motion, caused by the gravitational pull of orbiting planets. It is particularly effective at detecting:

1. Massive planets: The technique works best for planets with larger masses, as they cause more significant wobbles in the star's motion, making them easier to detect.

2. Close-in orbits: Planets with shorter orbital periods (i.e., close to their host star) are more easily detected because they cause more frequent wobbles, resulting in a stronger signal.

In summary, the radial velocity technique is most effective at finding massive planets with close-in orbits. However, it may be less effective for smaller planets or those with more distant orbits, as they cause weaker or less frequent wobbles in the host star's motion.

Sitting by a fire is an example of thermal radiation because the fire emits heat in the form of electromagnetic waves that are absorbed by nearby objects.

What is thermal radiation?

Thermal radiation is the transfer of heat energy in the form of electromagnetic waves, without requiring a medium to travel through. It can be emitted by any object with a temperature above absolute zero and can be absorbed by other objects, causing them to heat up.

Sitting by a fire is an example of thermal radiation because the fire emits electromagnetic radiation in the form of heat. When the fire burns, it produces thermal energy, which causes the molecules in the fire to vibrate and emit electromagnetic waves that carry thermal energy. These waves can be absorbed by nearby objects, including people sitting around the fire, causing them to heat up.

The transfer of heat through thermal radiation does not require a medium to travel through, unlike conduction and convection. This means that the heat can be transferred through the vacuum of space, making thermal radiation an important means of heat transfer in the universe, particularly for objects that are too far apart to transfer heat by conduction or convection.

To answer this question, we must first consider the conservation of momentum. In this scenario, we have three objects: a 2 kg object, a 3 kg object, and a 4 kg object. Let's call them A, B, and C, respectively.

Object A is moving in the x-direction with a velocity of 3 m/s, while object B is at rest. Object C has an initial velocity in the x-direction, which we need to determine.

After the collision, all three objects move at a velocity of 0.50 m/s in the x-direction. We know that the total momentum of the system must be conserved, meaning that the sum of the momentum of all three objects before the collision must equal the sum of their momentum after the collision.

Using the equation for conservation of momentum, we can set up the following equation:

A 250-g ball approaching at 8.0 m/s suddenly collides head-on with a 550-g ball travelling at that same speed. The speed of the 250-g ball just after the collision is 5.5 m/s.

To start, we can figure out the system's overall momentum before the collision:

P_initial = m1v1 + m2v2

P_initial = (0.55 kg)(8.0 m/s) + (0.25 kg)(-8.0 m/s) [since the second ball is moving towards the first ball, its velocity is negative]

P_initial = 1.6 kg m/s

Next, we can use the conservation of kinetic energy to find the speed of the 250-g ball just after the collision:

[tex]1/2m_1v_1^2 + 1/2m_2v_2^2 = 1/2m_1v_1f^2 + 1/2m_2v_2f^2[/tex]

where v1f and v2f are the velocities of the two balls after the collision.

We can simplify this equation since the initial kinetic energy of the system is equal to the final kinetic energy of the system (since the collision is elastic):

[tex]1/2m_1v_1^2 + 1/2m_2v_2^2 = 1/2m_1v_1f^2 + 1/2m_2v_2f^2[/tex]

We can solve for v2f:

[tex]v_2f = \sqrt{((m_1v_1^2 + m_2v_2^2 - m_1*v_1f^2)/(m2))[/tex]

where we can use the equation for conservation of momentum to find v1f:

[tex]m_1v_1 + m_2v_2 = m_1v_1f + m_2v_2f\\\\v_1f = (m_1v_1 + m_2v_2 - m_2*v_2f)/(m_1)[/tex]

Plugging these values into the equation for v2f:

[tex]v2f = \sqrt{((m_1v_1^2 + m_2v_2^2 - m_1*((m_1v_1 + m_2v_2 - m_2*v_2f)/(m_1))^2)/(m_2))[/tex]

Simplifying this expression:

[tex]v_2f = \sqrt{((2m_1m_2*(v_1 - v_2)v_2f)/(m_2(m_1 + m_2)))[/tex]

v2f = sqrt((20.55 kg0.25 kg*(8.0 m/s - (-8.0 m/s))v2f)/(0.25 kg(0.55 kg + 0.25 kg)))

The work done against gravity is completely recoverable because gravity is conservative.

In a conservative force, the work done is stored as potential energy and can be recovered as kinetic energy.

Explanation:

A conservative force is a force that does work on an object and the amount of work done by the force is independent of the path taken by the object. This means that if an object is moved from one position to another by a conservative force, the amount of work done by the force is the same, regardless of the path taken by the object between the two positions. The gravitational force is an example of a conservative force.

When an object is lifted against the force of gravity, work is done against gravity. This work is stored as potential energy in the object-Earth system, as the object gains gravitational potential energy. When the object is released and falls back to its original position, the potential energy is converted back to kinetic energy, and then to work, as the object does work on its surroundings.

Due to the conservatism of gravity, all of the labour done in defiance of it can be recovered.

The work performed is stored as potential energy in a conservative force and is recoverable as kinetic energy.

A conservative force is one that exerts force on an item while doing work that is independent of the path the object takes. In other words, regardless of the path the object takes between two points when being moved by a conservative force, the force does the same amount of work on the object. An illustration of a conservative force is the gravitational force.

Work against gravity is accomplished when an object is raised defying gravity's pull. As the object accumulates gravitational potential energy, this work is stored as potential energy in the object-Earth system. After being released, the object returns to its starting position.

The power output by the person is 418.5 W and they burned approximately 32.2 calories during this activity.

Power is the rate at which work is done, which is given by the formula P = W/t, where P is power, W is work, and t is time. In this case, the work done is the force applied multiplied by the distance covered, which is 66 N x 23 m = 1518 J. The time taken is 40 seconds. Thus, the power output is P = 1518 J / 40 s = 37.95 W.

However, since the person consumed 850 calories, which is equivalent to 3,556,400 J, and assuming that approximately 20% of this energy is used for work done, the person burned 0.2 x 3,556,400 J = 711,280 J during this activity, which is equivalent to 32.2 calories. Therefore, the power output by the person is 418.5 W and they burned approximately 32.2 calories during this activity.
