Question

145. If unit of mass is 1 kg, unit of time is 1 minute and unit
of acceleration is 10 m s-2, then unit of energy is
(a) 36 x 106 J
(b) 3.6 x 106 J
(c) 0.36 x 106 J
(d) 0.036 x 106 J​

Answer 1

Explanation:

3.6 × 10^6 J is the correct answer.

Answer 2

Your question is...

If unit of mass is 1 kg, unit of time is 1 minute and unit

of acceleration is 10 m s-2, then unit of energy is

Options...

(a) 36 x 106 J

(b) 3.6 x 106 J

(c) 0.36 x 106 J

(d) 0.036 x 106 J

My answer...

Dimensional formula of work is same as that of mass × ( Acceleration × T)²

Hence, 1 Joule = 1 × (10 ×60)²

= (600)²

= 360000

= 0.36 × 106 J

so, option (c) is correct....

Hope it helps...☺️☺️☺️
