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

Answer:

Mass = 5 unit

Length = 5 unit

Time =  0.5 unit

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

$Force = mass \times \frac{velocity}{time}$

$100 = mass \times \frac{10}{0.5}$

$mass = 5 units$

ii) For length we know that

$Force \times distance = energy/work$

$100 (d) = 500$

$Length = 5 units$

iii) for Time we know that

$Power = \frac{Energy}{time}$

$Force \times velocity = \frac{Energy}{time}$

$time = \frac{500}{100\times 10}$

$Time = 0.5 unit$
