Solution

Yes, you are correct in your assertion. If speed of light would really be 1m/s, then
E=m
Energy liberated on the nuclear reation of "m" kg of substance will be "m" joules.

Q. According to the quantum theory, a photon of electromagnetic radiation of frequency v has energy E = hv where h is known as planck's constant. According to the theory of relativity, a particle of mass m has equivalent energy E =

m c^{2}

, where c is speed of light. Thus a photon can be treated as a particle having effective mass m

= \frac{h v}{C^{2}}

. If a flash of light is sent horizontally in earth's gravitational field, then photons while travelling a horizontal distanced would fall through a distance given by

Q. Assertion :Mass and energy are not conserved separately but are conserved as a single entity called `mass-energy equivalence'. Reason: According to Einstein's special theory of relativity mass and energy are different manifestations of same and all related as

E = m c^{2}

The formula E = mc² states that the equivalent energy (E) can be calculated as the mass (m) multiplied by the speed of light (c = about 3×10⁸ m/s) squared. Write a program that accepts the mass of an object and determines its energy.
