Answer:
Friction Force
Explanation:
As we know that centripetal force is the product of mass and centripetal acceleration
so we know that
so here we have
so we have
This acceleration is given by the force which may be towards the center of the circular path
Here in the above case it is possible due to friction force.
Answer:

Explanation:
A transformer is a static electrical machine, it should be borne in mind that although the voltage can be increased or decreased, the power must always be equal.
For this case:
The power in the first coil can be calculated by means of the following formula.
where:
V = voltage = 12 [V]
I = current =2 [A]
a)
Therefore the power:
b)
Now in the second coil, the power must be the same:
