I believe the answer is Mouse/Herbivore. It was a question in my old lab haha.
Hope this helped!!

Answer would be: alternating.There is no electrical connection between the two coils. These only work if alternating current is supplied to the main coil. If DC was supplied, there would be no flow of current in the minor coil.
Answer:
The potential energy of a 2 kg mass at a height of 40 meters is 784 J
Explanation:
Potential energy is that energy that a body possesses due to the height at which it is located and whose unit of measurement of the International System of Units is the joule (J).
The potential energy of a body is the result of multiplying its mass by its height and by gravity:
Ep=m*g*h
Potential energy Ep, is measured in joules (J), mass m is measured in kilograms (kg), gravity, g, in meters / second-squared (), and height, h , in meters (m).
In this case:
- Ep=?
- m= 2 kg
- g= 9.8
- h= 40 m
Replacing:
Ep= 2 kg* 9.8 * 40 m
Solving:
Ep= 784 J
<u><em>The potential energy of a 2 kg mass at a height of 40 meters is 784 J</em></u>
Answer:
Explanation:
According to the law of conservation of energy, the amount of energy an electron gains after being accelerated is equal to its kinetic energy, that is, the electrical potential energy is converted into kinetic energy

Solving for v and replacing the given voltage:
<span>French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war’s expenses led to colonial discontent, and ultimately to the American Revolution.</span>
