<em>A clamp-type measuring instrument operates on the principle of; </em>
A. induction
Part A)
First of all, let's convert the radii of the inner and the outer sphere:


The capacitance of a spherical capacitor which consist of two shells with radius rA and rB is


Then, from the usual relationship between capacitance and voltage, we can find the charge Q on each sphere of the capacitor:

Now, we can find the electric field at any point r located between the two spheres, by using Gauss theorem:

from which

In part A of the problem, we want to find the electric field at r=11.1 cm=0.111 m. Substituting this number into the previous formula, we get

And so, the energy density at r=0.111 m is

Part B) The solution of this part is the same as part A), since we already know the charge of the capacitor:

. We just need to calculate the electric field E at a different value of r: r=16.4 cm=0.164 m, so

And therefore, the energy density at this distance from the center is
Answer:
The frequency increases by a factor of 3.
Explanation:
The relation between speed, wavelength and frequency of a wave is given by :

or

A wave travels at a constant speed. If the wavelength is reduced by a factor of 3, it would mean that the frequency increases by a factor of 3 because there is an inverse relationship between wavelength and frequency.

Explanation:
1. A rock sitting at the edge of a cliff has potential energy. If the rock falls, the potential energy will be converted to kinetic energy.
2. Tree branches high up in a tree have potential energy because they can fall to the ground.
3. A stick of dynamite has chemical potential energy that would be released when the activation energy from the fuse comes into contact with the chemicals.
4. The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism.
5. A stretched spring in a pinball machine has elastic potential energy and can move the steel ball when released.
6. When a crane swings a wrecking ball up to a certain height, it gains more potential energy and has the ability to crash through buildings.
7. A set of double "A" batteries in a remote control car possess chemical potential energy which can supply electricity to run the car.
