The voltage across the inductor is 69.82V

In an RL series circuit connected to an AC source, the voltage across the resistor and the voltage across the inductor are in phase with each other.

This means that the voltage across the resistor and the voltage across the inductor will have the same frequency and will be in the same phase. Since we know the voltage across the resistor is 85 V, the remaining voltage must be across the inductor.

The voltage across the inductor is equal to the total voltage from the AC source minus the voltage across the resistor, so the voltage across the inductor is

110V = [tex]\sqrt{VR2^{2}+VL2^{2} } \\\sqrt{85V^{2}+VL2^{2} } \\V_{L2} = \sqrt{110V^{2}- 85V^{2} } = 69.82V[/tex]

What is a gravitational force?

Gravitational force is a natural phenomenon by which all objects with mass attract each other. This force is one of the four fundamental forces of nature, and is the weakest of the four. It is the force that binds us to the Earth and keeps our feet firmly planted on the ground.

Part A: The gravitational force between any two bodies is inversely proportional to the square of the distance between them. Therefore, the force of gravity exerted by Earth on the spacecraft will be equal to the force of gravity exerted by the Moon on the spacecraft when the distance between them is equal to the Moon's orbit semimajor axis.

Part B: The Moon's orbit semimajor axis is 384,400 km. Therefore, the distance from Earth at which the force of gravity exerted by Earth on the spacecraft cancels the force of gravity exerted by the Moon on the spacecraft is 384,400 km.

What is projectile motion?

Form of motion experienced by an object or particle that is projected in gravitational field, such as from Earth's surface, and moves along curved path under the action of gravity only is called projectile motion.

The time of flight can be calculated using:

t = (2vsin(θ)) / g

t is the time of flight, v is the initial velocity, θ is angle of launch (measured from the horizontal), and g is acceleration due to gravity (which is -32 ft/s^2).

So, t = (210sin(80)) / -32

t = 0.519469684 seconds

To find the horizontal distance the ball will travel before hitting the ground:

d = vxt = vcos(θ)*t

The tension in the chain is the force acting on the child which is 394.76N.

What is tension the chain and calculate it?

The tension in the chain is equal to the force acting on the child in the seat. This force is equal to the child's weight, which is the force of gravity acting on the child's mass.

The weight of an object can be calculated using the formula:

Weight = mass x gravity

where mass is measured in kilograms and gravity is measured in meters per second squared. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2.

So, for a child with a mass of 40.2 kg, the weight would be:

Weight = 40.2 kg x 9.8 m/s^2 = 394.76 N

The tension in the chain is the force acting on the child which is 394.76N. However, it's important to note that this tension is in the direction of the force of gravity, which is downwards.

If the angle of the chain is different from the vertical direction, the tension in the chain will be affected by the angle and the force of gravity.

The spring's elastic potential energy decreases and the gravitational potential energy increases.

What do you mean by potential energy?

Potential energy is the energy an object possesses because of its position or state. It is the energy an object has due to its height, position, or chemical composition. The unit of measurement for potential energy is usually Joules (J).

There are different types of potential energy, such as gravitational potential energy (GPE), elastic potential energy (EPE), and chemical potential energy.

When a mass is attached to a vertical spring, it causes the spring to stretch. As the spring stretches, it stores potential energy in the form of elastic potential energy (EPE). As the spring stretches, the potential energy stored in it increases.

At the same time, as the mass is attached to the spring and moves downward, it loses gravitational potential energy (GPE) due to the work done by gravity on the mass. Since the mass is moving downward, the gravitational force is acting in the opposite direction of the displacement, resulting in a decrease in GPE. Therefore, as the mass moves downward, the EPE of the spring increases and the GPE of the mass decreases.

Therefore, the spring's elastic potential energy decreases and the gravitational potential energy increases.

Any force that changes the direction of motion toward the center of a circular motion is known as a centripetal force. The part of the force that produces the centripetal force is the part that is perpendicular to the velocity. Due to Earth's permanent axis of rotation, the direction of centrifugal force is always outward and away from the axis, which is the opposite of the direction of gravity at the equator and zero in the poles.

The direction of centrifugal force is always outward and away from the axis because the Earth revolves around a fixed axis. At the equator, it is therefore the opposite of the direction of gravity; at the poles, it is zero.

Centripetal acceleration is given by: a = v²/r

For particle 1: a₁ = v²/r

For particle 2: a₂ = (2v)²/2r = 2v²/r

For particle 3: a₃ = (v/2)²/r = v²/4r
