Question

3.convert a work of hundred gram into a system of unit which has unit of mass 200 gram unit of length 100 cm and unit of time as 30 second ​

Answer 1

Answer:

given : m = 100g

s = 10cm

t = 30 sec

.°. velocity (v) = s/t

= 10/30

= 0.3333 cm/s

Now, force (f) = ma = m*v/t

f = 100*0.3333/30

f = 1.111 N

we have,

Work done = Force * distance

W = f*s

W = 1.111* 10

W = 11.11 g cm² /s²
