a) How has our understanding of time been influenced by the discovery of the constancy of the speed of light?
b) piece of radioactive material of mass 2.5 kilogram undergoes radioactive decay. How much energy is released if 10 grams of this mass are converted to energy during the decay process?
c) A mass is moving in an inertial frame of reference at a velocity v relative to a stationary observer. The observer measures an apparent mass increase of 0.37%.Calculate the value of v in m/s.
