Answer:
Option c) mass
Explanation:
With the increase in energy in energy of an object there will be an increase in its mass.
Also from Einstein's mass-energy equivalence,
where
m = mass of the object
c = speed of the object (usually speed of light or close to it)
which states that energy and mass are inter convertible.
From which it can be concluded that if an object acquires additional energy, it also acquires additional mass.
<span>light colored and smooth surface would most likely be the best reflector of electromagnetic energy.Light, shiny surfaces are the best reflectors of radiation and they will allow the waves to reflect and bounce off rather than absorb. we can consider mirror as the example ,it will only reflect the light energy falling on them and it will not absorb. The darker coloured and rough surfaced substances will definitely absorb some amount of light falling on it. so light coloured smooth or shiny surfaced material would be the best reflector for electromagnetic energy.</span>
Answer:
For Total energy and momentum to be conserved, the minimum energy of the photons released is equal to twice the rest mass energy of an electron that is 
The annihilation of electron -positron cannot produce a single photon. It is prohibited by the law of conservation of energy and momentum.
