The positive x direction is 0 Nm, positive y direction is 10 Nm, negative x direction is 0 Nm.

The torque, also known as the moment of force, is given by the cross product of the position vector (r) and the force vector (F).

The magnitude of the torque is given by the magnitude of the cross product, which is equal to the product of the magnitudes of the vectors (r and F) multiplied by the sine of the angle between them.

In the case of (a) positive x direction, the torque about the origin is given by:

τ = r x F = (2.0 m) x (5.0 N) x sin(90°) = 3.0 m x 5.0 N = 0 Nm.

In the case of (b) positive y direction, the torque about the origin is given by:

τ = r x F = (3.0 m) x (5.0 N) x sin(90°) = 2.0 m x 5.0 N = 10 Nm.

In the case of (c) negative x direction, the torque about the origin is given by:

τ = r x F = (2.0 m) x (-5.0 N) x sin(90°) = 3.0 m x 5.0 N = 0 Nm.

You can start the problem by using the formula for capacitance, C = Q/V, where C is the capacitance, Q is the charge stored on the capacitor, and V is the potential difference across the capacitor.

A capacitor is a passive electrical component that stores electrical energy in an electric field. It consists of two conductive plates, separated by an insulating material called the dielectric. When a voltage is applied across the conductive plates, an electric field is created, which stores energy in the dielectric. The ability of a capacitor to store electrical energy is measured in farads (F).

Given that Capacitor 2 has half the capacitance and twice the potential difference as Capacitor 1, you can express the capacitance and potential difference of Capacitor 2 in terms of those of Capacitor 1.

C₂ = 1/2 × C₁ V₂ = 2 × V₁

You can use these equations to find the ratio of the stored energy in the two capacitors. The stored energy in a capacitor is given by the formula U = 1/2CV², where U is the stored energy, C is the capacitance, and V is the potential difference.

Uc1 = 1/2C₁V₁² Uc2 = 1/2C₂V₂²

By substituting the values of C₂ and V₂ in terms of C₁ and V₁, you can find the ratio of the stored energy in the two capacitors:

Uc1/Uc2 = (1/2C₁V₁²) / (1/2×(1/2C₁) (2V₁) ²) Uc1/Uc2 = 1/8

The ratio of stored energy in the two capacitors is 1/8.

The force exerted by the water on the wall will be equal to 160 N. Newton's third law of motion is seen taking place here.

The force exerted by the water on the wall is calculated using the impulse-momentum principle. The principle states that the change in momentum of an object is equal to the impulse, or the force applied over a certain period of time. In this case, the change in momentum is equal to the initial momentum of the water (mass flow rate multiplied by velocity) minus the final momentum of the water (mass flow rate multiplied by final velocity) and the time is assumed to be very small.

The assumptions made in the calculation of force exerted by the water on the wall are:

The water hits the garage instantaneously.

The water flow rate is constant and no water is lost during the impact.

The water hits the garage uniformly over the entire area and not just at one point.

The garage door is not moving before the impact. These assumptions are made to simplify the calculation and to make it more accurate. It is important to note that in real-world scenarios, these assumptions may not always hold true and the force exerted by the water on the wall may be different.

Force exerted by the wall on the water, F = dP/dt

= (P2 - P1)/dt

= dm*(V2 - V1)/dt

= (V2 - V1) x dm/dt

= (0 - 16) x 10

The apparent weight of the passenger at the lowest point is 90 kg and at the highest point it changes due to the centrifugal force.

What is centrifugal force?

The centrifugal force is an apparent force that is observed in a rotating reference frame. It is the force that appears to push objects away from the center of rotation. It is not a real force, but rather a pseudo-force that is caused by the inertia of an object in motion. In other words, it is the inertia of an object that makes it appear as if there is a force pushing it away from the center of rotation.

A. At the lowest point of the circle, the rider is at the bottom of the Ferris wheel and moving at the same velocity as the wheel. Therefore, the apparent weight of the passenger is equal to the true weight, which is 90 kg.

B. At the highest point of the circle, the rider is at the top of the Ferris wheel and is moving at a slower velocity than the wheel. Therefore, the apparent weight of the passenger is less than the true weight. This effect is known as the centrifugal force. The formula for the apparent weight at the top of the Ferris wheel is:

Apparent weight = True weight x (1 - (v^2/r^2))

where v is the velocity of the Ferris wheel and r is the radius of the Ferris wheel.

In this case, the velocity of the Ferris wheel is (2πr)/T = (2π40ft)/24s = 4.71 ft/s

The radius of the Ferris wheel is 40ft

So, the apparent weight of a 90 kg passenger at the highest point of the circle is:

90 kg x (1 - (4.71^2 / 40^2)) = 90 kg x (1 - 0.12) = 90 kg x 0.88 = 79.2 kg.

Therefore, due to centrifugal force the apparent weight of the passenger at the highest point of the circle is 79.2 kg.
