The potential V(z) on the z axis due to the ring can be expressed as: V(z) = ke*Q/(2*r) * ln(z/r + (z/r)^2 + 1).

Potential is a term used to describe the ability of something or someone to achieve a desired outcome or result. It is the capacity to do or become something in the future. Potential is often used to refer to a latent or undeveloped ability, talent, or capability.

Part A:
The potential V(z) on the z axis due to the ring can be expressed as:
V(z) = ke*Q/(2*r) * ln(z/r + (z/r)^2 + 1)
where ke = 1/4 phi e0, Q is the total charge, and r is the radius of the ring.

Part B:
The magnitude of the electric field E on the z axis for z > 0 can be expressed as:
E = ke*Q/(2*r^2) * (z/r + 1/z)
where ke = 1/4 phi e0, Q is the total charge, and r is the radius of the ring. This expression follows from the definition of the electric field, E = -grad(V). Taking the gradient of V(z) in Part A yields the expression for E.

Answer:

Explanation:

To determine if the shooter could have come from the penthouse, we need to calculate the angle of elevation from the penthouse to the tree. We can use trigonometry to do this.

We know that the height of the penthouse is 85 feet, and the distance from the penthouse to the tree is 60 feet. We can use the tangent function to calculate the angle of elevation:

tan(angle of elevation) = opposite / adjacent

opposite = height of penthouse = 85 feet

adjacent = distance from penthouse to tree = 60 feet

tan(angle of elevation) = 85 / 60

angle of elevation = arctan(85/60)

Now we have the angle of elevation, we can determine if the shooter could have come from the penthouse. If the angle of elevation is greater than 90 degrees, the shooter would have had to shoot at an impossible angle, and the shots could not have come from the penthouse.

In this case, the angle of elevation is approximately 62.9 degrees, which is less than 90 degrees. So the shots could have come from the penthouse.

It's important to note that this is a simplified calculation based on the data provided, and it is not a conclusive evidence. A detailed investigation is required to gather all the facts and evidence before determining the shooter's location.

The following the expressed as functions

A) Energy of UL (t) = 0.5 LI(t)2

B) Energy of UC(t) = 0.5 Q(t)2/C

Energy can be defined as the capacity to perform work in most contexts. Therefore, everything that is capable of doing work possesses energy. Work is also referred to as causing or making change when referring to energy. Each time we perform a task, energy is either transformed or transferred. As a result, the amount of energy in the universe will never change because it takes on different forms with each use.

In other words, life is impossible without energy. Try to come up with an idea that doesn't require any energy. You're not going to have an answer, I'm afraid. A baby sleeping, a ball bouncing, even a beating heart all have energy. The same goes for a hot beverage in a cup.

To solve this, we must first understand how current behaves in an L-C circuit.

If there is an initial current owing, it will begin charging the capacitor.

The inductor will keep this current flowing until the charge accumulates enough to oppose the current, at which point the current will stop and the capacitor will be charged.

The capacitor will then force the current in the opposite direction, while the inductor will try to keep the current constant.

Finally, the current will flow sinusoidally through the circuit, charging the opposite plates of the capacitor.

The mathematical derivation is in the book, and the current value is

                                          I(t) =I0cos (ωt)

Without an external voltage source, the frequency will be the resonance frequency of the capacitor and the inductor, ω = [tex]1\sqrt{LC}[/tex]. This tells us UL(t), but we need the charge on the capacitor. Either integrate the current(because it is the derivative of Q(t) or use the phasor diagram.

It is typically expressed in units of meters per second (m/s) or miles per hour (mph). The direction of the velocity vector is the same as the direction of the displacement vector. For example, if an object is moving to the right, its velocity vector points to the right. If the object is not moving, its velocity is zero.

Therefore, speed is 3.984m/s upwards

Part (d) → Hmax=2.00+((3.984)^2)/2g

Or Hmax =2.00+15.8723/19.6

=2.00+0.81 m

=2.81 m

Therefore, the height Hmax is 2.81 m.
