Question

In a new unit system, 1 unit of time is equal to 10 second, unit of mass is 5 kg and 1 unit of lenth is 20 m. in this new system of units, i unit of energy is equal to

Answer 1

energy = (M^1 L^2 T^-2)=( 5.400 100^-1)=20 UNITS

Answer 2

Answer:

20J

Explanation:

HERE 1UPON2 IS DIMENSIONLESS SO FORMULA FOR ENERGY=1UPON2 MV2 SO M=5KG V IS VELOCITY = DISPLACEMENT UPON TIME MEANS 20UPON100 SQUARE 5*400UPON100=20J
