Question

find the unit of length,mass and time if the unit of force, velocity and energy are respectively 100N,10ms^1and 500J​

Answer 1

Mass = 5 unit

Length = 5 unit

Time = 0.5 unit

Step-by-step explanation:

As we know that the units are as following

Force = 100 N

Velocity = 10 m/s

Energy = 500 J

i) For mass we know that

`Force = mass * (velocity)/(time)`

`100 = mass * (10)/(0.5)`

`mass = 5 units`

ii) For length we know that

`Force * distance = energy/work`

`100 (d) = 500`

`Length = 5 units`

iii) for Time we know that

`Power = (Energy)/(time)`

`Force * velocity = (Energy)/(time)`

`time = (500)/(100* 10)`

`Time = 0.5 unit`
