Air or any sort of gas is not that good in conducting heat in relation to other materials.
<span>since foam consists of many bubbles with trapped gas it both stops convection by simply being in position, and prevents conduction of heat through it, due to the gas inside</span>
We have: a = v/t
Here, t = 2 s [ Given ]
a = 9.8 m/s² [constant value for earth system ]
Substitute their values into the expression:
9.8 = v/2
v = 9.8 × 2
v = 19.6 m/s
In short, Your Answer would be Option B
Hope this helps!
