Answer: D.) electromagnetic induction
Explanation: Electroctromagnetic induction may be explained as a process whereby electric current is induced or produced by difference in potential resulting from the movement of conductor across a magnetic field.
In simple terms, an electromotive force is induced when a magnet is moved through a conducting loop.
The electromotive force produced by moving a magnet through a conducting loop can be represented by the relation:
E = - N (dΦ / dt)
Where E = electromotive force in voltage
N = number of loop in conductor
dΦ = change in magnetic Flux
dt = change in time
Answer:
A)
B) 
Explanation:
Using the free body diagram and according to Newton's first law, we have:

A) Solving (1) for T:

B) Solving (2) for F:

3 trillion= 3X10^<span>12
5 thousanths= 5X10^-3
730000000000000= 7.3X10^14
0.000000000082= 8.2X10^-11</span>
The type of potential energy is elastic energy
Answer:
Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy.
