Question

6.4k j of energy per minute is produced in a nuclear reactor. Find out the Number of fission that take place in one hour, if the energy released per fission is 3.2 × 10^ -11 J.

Answer 1

Given:

6.4k j of energy per minute is produced in a nuclear reactor

Solution:

• Energy released in 1 min = 6.4KJ
• Energy released in 60 min

➠ 6.4 × 60 KJ

➠ 384 KJ

➠ 3.84 × 105 J

Hence, 3.8 × 10-¹¹ KJ energy is released in 1 fission.

Now,

➠ 1 × 3.84 × 10⁵ /3.2 × 10¹¹

➠ 1.2 × 10¹⁶ fission.

Answer 2

${\textbf{\textsf{{\color{Magenta}{⛄A}}{\red{N}}{\purple{S}}{\pink{W}}{\blue{E}}{\green{R}}{\red{♡}}{\purple{࿐⛄}}{\color{pink}}}}}$

Energy produced in one minute = 6.4 k j

Energy produced in 60 minutes = ?

So ,

$6.4 \times 60 \: kj$

$= 384 \: kj \:$

Therefore , 384 k j energy produced in one hour .

Then ,

$1 \times 3.84 \times {10}^{5} \div 3.2 \times 10$

$= 1.2 \times {10}^{16}$
