The cannonball lands 68.73 meters from the base of the wall.

The time it takes for the cannonball to fall from the castle wall to the ground is given by:

t = sqrt(2h/g)

= sqrt(210.5/10)

= sqrt(2.1)

= 1.45 seconds

The distance the cannonball travels horizontally in this time is given by:

d = vt

= 47.4 * 1.45

The power, the resistor and time is I²₀R e-2Rt/L and - I₀²R  e-2Rt/L .

Work rate or energy delivery time is expressed as W/t, where W is the quantity of work completed or energy delivered, and t is the time interval.

A passive electrical device with two terminals that controls or limits the flow of electricity across electrical circuits. The main function of a resistor is to lower the voltage and reduce the current flow in a specific area of the circuit.

a) L di/dt + iR = 0 -Rt/L

= I = I₀ e

At t=0.  I = I₀

= Pr = I²R = I₀ R e = -2Rt/t

= Pr (t) = I²₀R e-2Rt/L

b) Energy of inductor = 1/2 L I²

= 1/2 L I₀²    e-2Rt/L

Power, Pl (t) = dE/dt

= d/dt (1/2 LI₀² e-2Rt/L)

= 1/2 t I₀² ( e-2Rt/L) e-2Rt/L

Pl (t) = - I₀²R  e-2Rt/L

B. Noise decreases the loudness of analog signals but does not affect the loudness of digital signals.

Noise is any extraneous interference that can affect the quality of a signal being transmitted.

Noise can cause analog signals to become weaker or distorted, which can reduce the loudness of the signal and make it more difficult to interpret. In contrast, noise does not affect the loudness of digital signals in the same way.

Digital signals are transmitted using a series of ones and zeros, which can be easily distinguished from noise. This means that digital signals are less susceptible to the effects of noise, and are generally considered to be more reliable than analog signals for this reason.

Other reasons to use digital signals instead of analog signals include the fact that digital signals are easier to store and transmit over long distances, and that they can be more easily processed by computers.

The impulses and changes in momentum are identical because equal forces are applied over equal periods of time.

The momenta of the two carts are identical since they both begin at rest and experience equal changes in momentum. We are aware that force is the same as mass multiplied by acceleration. Due to the initial resting state of both carts, u = 0 m/s, and the plastic cart moves 1 m. Newton's second law states that when the same force is applied to the two carts, the plastic cart will have more final momentum than the lead cart because of the momentum principle. Newton's third law states that every object feels the same force for the same length of time, which results in the same impulse and consequent change in momentum.

The difference between the string's tension at the bottom of the circle and at the top of the circle is 2mg.

radius of circle = r and constant speed is maintained = v

At the top of the circle, ΣF = FT + mg = mv^2/r, where F is the force acting on the string, T is tension, m is mass and g is gravitational acceleration.

Here as the ball moves in circle it carries centripetal force = mv^2/r.

Then FT = mv^2/r – mg.

At the bottom of the circle, ΣF = FT – mg = mv^2/r, So

FT = mv^2/r + mg
