Answer:
A DC generator is the same as a(n)
C. armature
Answer:
The temperature of the water increases because the nuclear reactor heats it producing steam
Explanation:
The nuclear power plants are usually defined as those thermal plants where the nuclear reactors are used in order to generate heat that eventually leads to the rotating of the turbines and produces electricity. Here the nuclear reactor heats the water, and it increases above a temperature of 100°C, where this heat energy plays a key role in the entire process. It is an efficient method as it does not lead to the emission of any green house gases that are harmful to the environment.
B. Pairs
“Forces always come in pairs — equal and opposite action-reaction force pairs.”
Answer:
15m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 40m/s
Time taken = 2s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time;
Acceleration = 
Acceleration = 
= 15m/s²
A sound wave is a mechanical wave and cannot travel through empty space. It needs to travel through a medium of some kind. To remember this, the saying "no one can hear you scream in space" is somewhat helpful considering sound waves cannot travel through an empty vacuum like such. An electromagnetic wave ( EM wave ) does not need a medium to travel and can travel freely through empty space.
