Answer:
A. Kinetic energies are equal.
Explanation:
The kinetic energy of the bodies will be equal since the mass and speed are the same.
Kinetic energy is the energy due to the motion of a body.
Mathematically;
K.E = m v²
m is the mass
v is the speed
The kinetic energy is a scalar quantity with no regard for direction.
Explanation:
It is given that,
Input voltage,
Input current,
Output current,
Number of turns in the secondary side of transformer,
We need to find the number of turns in the primary side of the transformer. The current to the number of turns in the input and output is given by :
Substituting all the above values
So,
So, the number of turns in primary side of the transformer is 5885.
