Question

Find the value of 10 joule on a system having 100 g 10 cm and 30 sec as fundamental unit

Answer 1

Answer:

Explanation: I'm using direct method you can also use dimensional method to find the answer

Follow...10 joule = 10 kg m^2 / s^2

Now according to the que.

10 J = 10 × 1kg/100 g× 1 cm^2/100cm^2 × 1 s^2/30×30 s^2

=10×1000g/100g ×1/100cm^2× 1/900s^2

=100×1/100×1/900

=1/900 J

=0.001J
