Question

a nuclear reactor if 5g of fuel is completely converted into energy.
(a) Find the amount of energy released

Answer 1

Answer:

Energy released during a nuclear reaction = 4.5 × 10¹⁴J

Explanation:

As per the question,

Given mass of the material = 5g =0.005 kg

( 1 kg = 1000 g)

As we know that,

According to Einstein's relativity equation,

E = mc²

where,

c = Speed of light = 3 × 10⁸m/s

Now put the values in given equation,w we get

E = 0.005 × (3 x 108)²

E = 4.5 x 10¹⁴J

Answer 2

Answer:

By einstein energy mass relation ,

E = mc²

Mass = 5 grams = 5 / 1000 kilograms

E = ( 5 / 1000 ) × ( 3 × 10⁸ )²

$e \: = 4.5 \times {10}^{14} \: joules$
