The average kinetic energy of the atoms that make up a substance which is changing from a liquid to a solid is <span>decreasing. The answer is letter A. This is because there is more room for movement of atoms if the pahse is in liquid than in solid.</span>
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. ... Kinetic energy can be transferred between objects and transformed into other kinds of energy
Answer:
a coil rotating in a magnetic field to change its flux
Explanation:
It is given that,
Electric field, 
The relation between the electric force and the electric field is given by :

Where
q is the charge
(a) Charge on the electron, 
Electrostatic force,

(b) If an electron is missing, the net charge remains the same only sign changes.
So, force becomes,
Hence, this is the required solution.
