Question

How much energy is contained in a particle that has a mass of 1 ug

Answer 1

Answer: 9x 10^13 Joules

Explanation:

According to the relation E = mc^2

where E is the energy released

m is the mass of particle

c is the speed of light

c = 3 x 10^8 m/s

E = [1x 10^(-3) x {3x 10^8}^2]

= 9 x 10^13 Joules

Therefore 9x10^13 joules is the energy released.

Answer 2

Answer:

E=ENERGY , ΔM= MASS=1ug, C = speed of light

using the formula, Energy equals mass times the speed of light squared.

E  = Δmc²

   = [1x $10^{-3}$ x {3x $10^{8}$}²]

  = 9 x $10^{13}$Joules

So, 9x$10^{13}$ joules is the amount of energy released.

In physics, the mass-energy equation is the relationship between mass and energy in a system's rest frame, where the two values differ by a constant and the units of measurement. The principle is described by the famous physicist Albert Einstein i.e-

 E = mc^2.
