Question

1 gram padarth m samtulya urja hogi

Answer 1

1 gram padarth m samtulya urja hogi

Mass–energy equivalence states that anything having mass has an equivalent amount of energy

Formula is

E = mC²

m = mass in kg

=> m = 1 /1000 = 10⁻³ kg

C = speed of light = 3 × 10⁸ m/s

E = 10⁻³ × (3 × 10⁸)²

=> E =  10⁻³ × 9 × 10 ¹⁶

=> E = 9 × 10 ¹³  Joules

=> E = 90 × 10¹² Joules

=> E = 90 TJ

Answer 2

Answer: The equivalence energy will be $9\times10^{13}J$

Explanation:

Given that,

Mass of matter $m = 1 g = 10^3\ kg$

We know that,

Einstein's equation

The energy of the matter is the product of mass of the matter and speed of light.

$E = mc^2$

$E = 10^{-3}\times(3\times10^8)^2$

$E = 9\times10^{13}J$

Hence, The equivalence energy will be $9\times10^{13}J$
