Question

solve the following equation 0.8 = x/0.5
​

Answer 1

Step-by-step explanation:

Given:-

Mass of body ,m = 10Kg

Velocity ,v = 5m/s

To Find:-

Kinetic Energy ,KE

Solution:-

As we know that the energy possess by body due to its motion is called Kinetic Energy.

• KE = 1/2mv²

Where,

KE is the Kinetic Energy

m is the mass

v is the speed/velocity

Substitute the value we get

→ KE = 1/2×10×5²

→ KE = 1/2× 10×25

→ KE = 250/2

→ KE = 125 J

Therefore, the kinetic energy of the body is 125 Joules..

Hence, Option (b) 125 J is the correct answer .

Answer 2

Step-by-step explanation:

Given equation is 0.8 = x/0.5

=>0.8×0.5=x

=>0.40=x

=>x=0.40

=>x=0.4

The value of x=0.4

Check:-

RHS:-

0.4/0.5

=>4/5

=>0.8

=>LHS

Verified.
