Question

is the units of force energy and velocity at 10 Newton 100 use and 5 metre per second find the units of length mass and time​

Answer 1

Answer:

Step-by-step explanation:

The Dimensional formulae of

force = [ MLT^-2 ]

energy = [ML²T^-2]

velocity = [LT^-1]

Thus We have

[MLT^-2] = 10N.......(i)

[ML²T^-2] = 100J .....(ii)

[LT-1] = 5ms^-1 .......(iii)

and

Dividing equation (ii) by eq.(i) ,we have

[L] = 100J/10N = 100Nm/10N = 10m.

Substituting the unit of [L] in eq. (iii) , we have

[T^-1] = 5ms^-1/[L] = 5ms^-1/ 10m

[ T ] = 10m/5ms^-1 = 2s.

Substituting the units of [L] and [ T] in eq.( i) we have

[M] = 10N / [L] [T^-2] = 10N × 4s² / 10m = 4kg.

hope it helps u buddy..

plss mark me as brainliest : )
