Power is the rate of energy. Mathematically, it is
Power (p) = Energy(E) / Time(t)
Hope this helps!
Explanation:
Below is an attachment containing the solution
Answer:
-The battery-the power source
-Closed conducting loop
Explanation:
-To produce an electric current, the following requirements must be met:
-A battery-This is the energy source than will do work on the charge thus moving from a low energy location to high energy location.
-Closed Conducting Loop-The loop is usually made of copper wires due to their high electric conductivity.
Answer:
1070 Hz
Explanation:
First, I should point out there might be a typo in the question or the question has inconsistent values. If the tube is 40 cm long, standing waves cannot be produced at 42.5 cm and 58.5 cm lengths. I assume the length is more than the value in the question then. Under this assumption, we proceed as below:
The insert in the tube creates a closed pipe with one end open and the other closed. For a closed pipe, the difference between successive resonances is a half wavelength
.
Hence, we have

.
The speed of a wave is the product of its wavelength and its frequency.
