Answer: The center of mass is at a distance of 0.36R from the center C' of the smaller circle.

Explanation: To find the position of the center of mass, we can consider the plate without the hole as one object and the removed piece as another object. The center of mass of the plate without the hole is at the center C, which is also the center of the larger circle. The center of mass of the removed piece is at the center C' of the smaller circle.

We can find the distance between these two centers of mass by subtracting the contribution of the removed piece from the center of mass of the plate without the hole. Since the removed piece has a smaller mass and is located at a distance of 0.8R from the center C, the distance between the two centers of mass is (0.8R) - (0.5R) = 0.3R.

Finally, we add the distance between the center C' of the smaller circle and the center of mass of the removed piece, which is R/2, to get the position of the center of mass of the entire plate. Therefore, the center of mass of the plate is located at a distance of 0.3R + 0.5R = 0.8R from the center C, in the direction of the center C'. Thus, the center of mass is located at a distance of 0.36R from the center C'.

True. Angular acceleration is equal to the torque divided by the moment of inertia. The moment of inertia is a measure of an object's resistance to angular acceleration, so if the torque is constant, then the angular acceleration will be proportional to the torque.

Acceleration is the rate at which the velocity of an object changes over time. It is the change in velocity divided by the time taken for the change to occur, measured in meters per second squared (m/s2). Acceleration can result from a change in direction, speed, or both. It can also be caused by an external force, such as gravity, a push, or a pull. Acceleration is an important concept in physics, as it is a key factor in the motion of objects. It can also be used to determine how quickly an object is moving, as well as the forces that affect it.

The energy required to make one He-3 nucleus is 3.27 MeV.

The formation of He-3 can occur through several nuclear reactions, including the fusion of two deuterium nuclei, the decay of tritium, and the capture of a neutron by He-3. The energy required to make one He-3 nucleus varies depending on the specific reaction that is taking place.

However, the fusion of two deuterium nuclei, which produces He-3 and a proton, is one of the most common and energy-efficient reactions used to create He-3. This reaction requires an energy input of 3.27 MeV (mega-electron volts) to overcome the electrostatic repulsion between the positively charged deuterium nuclei and bring them close enough together for the strong nuclear force to take over and fuse the nuclei.

Regarding the balance of nuclear equations, all nuclear reactions must obey the laws of conservation of mass and conservation of charge. This means that the sum of the mass numbers and the sum of the atomic numbers (proton numbers) must be equal on both sides of the equation. Therefore, nuclear equations must be balanced to ensure that the same number of positive charges and the same mass are present on both sides of the equation.

Gravity provides the force needed for circular orbits, while velocity determines the size of the orbit. Kepler's laws relate orbit period, semi-major axis, and orbital velocity. The greater the gravitational force, the faster the object must move to maintain a stable orbit.

The relationship between gravity and velocity of orbiting objects is that gravity provides the centripetal force needed to maintain a circular orbit, and the velocity of the orbiting object determines the size of the orbit.

The greater the gravitational force between two objects, the faster an object must move to remain in a stable orbit around it. This relationship is described by Kepler's laws of planetary motion, which state that the square of the period of an orbit is proportional to the cube of the semi-major axis of the orbit.

This means that objects in larger orbits take longer to complete a full orbit than objects in smaller orbits, and the velocity required to maintain a circular orbit is proportional to the size of the orbit.

According to the question the magnitude of the acceleration is 36 m/s².

Acceleration is the rate of change of an object’s velocity, which is the speed and direction of the object’s motion. Acceleration is caused by a net force, which can come from either an outside source or from internal forces within the object itself. Acceleration is a vector quantity, meaning it has both magnitude (the amount of acceleration) and direction. When an object is accelerating, its velocity changes over time, either increasing or decreasing.

The magnitude of the acceleration of an object moving in a circular orbit is given by the formula:
a = v²/r
where a is the magnitude of the acceleration, v is the velocity of the object and r is the radius of the circular orbit.
In this case, the velocity at time t = 0.75 s is 8 m/s² x 0.75 s = 6 m/s.

The time between the arrival of the p-wave and s-wave becomes greater because the s-wave travels slower than the p-wave. This is because the s-wave travels through solid material, which is denser than the material through which the p-wave travels.

As a result, the s-wave encounters more resistance and travels at a slower speed. This delay in the arrival of the s-wave compared to the p-wave is used by seismologists to calculate the distance between the earthquake epicenter and the recording station, which is an important factor in earthquake detection and monitoring.
                                  The time between the arrival of the P-wave and S-wave becomes greater due to the difference in their velocities and the increasing distance from the earthquake's epicenter. P-waves travel faster than S-waves, so they arrive first at a seismic station.

                                        As the distance from the epicenter increases, the time difference between the arrival of these waves also increases.

The unstretched length of the spiral spring is found to be 12 cm when applied force.

Let's assume that the unstretched length of the spiral spring is L cm. When a force of 4N is hung on it, the spring extends by x cm. From Hooke's law, we know that the force exerted by a spring is directly proportional to the extension of the spring, provided the limit of proportionality is not exceeded. Therefore, we can write,

4 = kx ............ (1), spring constant is k.

Similarly, when a force of 6N is hung on it, the spring extends by (x+4) cm. Again, using Hooke's law, we can write,

6 = k(x+4) ............ (2)

Now, we can solve these two equations simultaneously to find the values of k and x. From equation (1), we have,

k = 4/x

Substituting this value of k in equation (2), we get,

6 = 4(x+4)/x

6x = 4x + 16

2x = 16

x = 8

Therefore, the extension of the spring when a force of 4N is hung on it is 8 cm. Now, we can use this value of x to find the unstretched length of the spring,

L = x + 4 = 8 + 4 = 12 cm

To find the angle at which the car hits the water, we can follow these steps:

1. Convert the car's speed from kmph to meters per second (m/s): 54 kmph * (1000 m/km) / (3600 s/h) = 15 m/s.

2. Determine the time it takes for the car to fall 40 meters vertically. Using the equation:

[tex]h = 0.5 * g * t^2[/tex]

where

h is the height,

g is the acceleration due to gravity (9.8 m/s²), and

t is the time in seconds.

We can solve for t:

 [tex]40 = 0.5 * 9.8 * t^2[/tex]
[tex]80 = 9.8 * t^2[/tex]
[tex]t^2 = 8.16[/tex]
t ≈ 2.86 s

3. Calculate the horizontal distance the car travels in the air during the 2.86 seconds:

Horizontal distance = initial horizontal speed * time

Horizontal distance = 15 m/s * 2.86 s

                                  ≈ 42.9 m

4. Calculate the angle at which the car hits the water using the inverse tangent function (arctan) of the vertical distance (40 m) divided by the horizontal distance (42.9 m):

Angle = arctan(40/42.9)

The mirror displacement d is 317.12 nm. In a Michelson interferometer, interference fringes are created due to the interference of two beams of light.

A Michelson interferometer is a device used to measure small changes in the distance between two mirrors. It consists of a beam splitter, two mirrors, and a detector. One beam of light is split into two and travels to the mirrors, where they are reflected back towards the beam splitter. The two beams of light then recombine at the detector, creating an interference pattern.

When one of the mirrors is moved, the interference pattern shifts. The amount of shift depends on the distance moved and the wavelength of the light being used. By measuring the shift in the interference pattern, we can determine the displacement of the mirror.

In this problem, we are given that 250 interference fringe shifts were counted when the mirror was moved a distance d. The wavelength of the light being used is 632.8 nm.

Each interference fringe shift corresponds to a change in the path difference between the two beams of light by one wavelength. So, the total change in the path difference is 250 times the wavelength of the light:

250 × 632.8 nm = 158,200 nm

Therefore, the mirror displacement d is 158,200 nm. However, this displacement is in both directions (i.e., the mirror moved back and forth). To find the displacement in just one direction, we divide by 2:

d = 158,200 nm / 2 = 79,100 nm

Therefore, the mirror displacement d is 79,100 nm in one direction.

The surface temperature of a red giant is around 3,000 Kelvin, which is much lower than the surface temperature of the sun, which is around 5,800 Kelvin.

Temperature is a physical quantity that describes how hot or cold something is. It is usually measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). Temperature is an important factor in many scientific and biological processes, and can affect the rate of chemical reactions, the behavior of living organisms, and the density of air. Temperature is also used to describe the intensity of heat energy, which is measured in joules or calories.

A red giant is a luminous, cool star with a surface temperature lower than that of the sun. Typically, the surface temperature of a red giant is around 3,000 Kelvin, which is much lower than the surface temperature of the sun, which is around 5,800 Kelvin.

An object weighing 50 kg, the Schwarzschild radius is roughly

1.70 × 10⁻³³km.

In the following formula, the Schwarzschild radius (Rs) is denoted.

Rs = (2GM) / c²

Where M is the object's mass, G is the gravitational constant, and c is the speed of light.

The mass M for a 50 kg object can be translated into kilos as follows:

M = 50 kg × (1 kg/2.246 lbs) = 22.6796 kg.

The Schwarzschild radius can be determined using the provided values of     G = 6.67430× 10⁻¹¹ N m2/kg² and c = 299792458 m/s as follows:

Rs = 2 ×6.67430 ×10⁻¹¹ N m/kg² * 22.6796 kg) ÷ (299792458 m/s)².

Rs = 1.695 10⁻²⁷ meters.

We can divide this by 1000 twice to get kilometers:

R = 1.695 x 10⁻²⁷ meters (1 km = 1000 m)

Rs ≈ 1.70 × 10⁻³³km

Therefore, an object weighing 50 kg, the Schwarzschild radius is roughly 1.70 × 10⁻³³km.
