Answer 1

this isthe the answer gays option a

Answer 2

Answer:

The CGS unit of energy can be written as gm cm²s⁻².

Therefore the option (c) is correct.

Explanation:

• Work is the transfer of energy from or to the body by applying the force along the displacement.

             $Energy=(Force)(displacement)$               ..........(1)

We know that $Velocity,(v)=\frac{x}{t} =cms^{-1}$

where $x=distance(cm)$

          $t=time(sec)$

Now $Acceleration(a)=\frac{dv}{dt}=cms^{-2}$

We know  $Force , F=ma$

⇒  $F=(g)(cms^{-2})=gcms^{-2}$

Put the unit of force in eq.(1):

$Energy=(gcms^{-2})(cm)\\Energy=gcm^{2}sec^{-2}$

Therefore the unit of energy  will be $gcm^{2}sec^{-2}$.
