Answer:
Explanation:
As we know that the rate of heat transfer due to temperature difference is given by the formula
here we know that
A = 4 m x 7 m
thickness = 30 cm
temperature difference is given as
now we have

Weight (W), the normal force( N), and the tension force( T )in the string will all be forces operating on the box.
<h3>What is tension force?</h3>The tension force is described as the force transferred through a rope, string, or wire as opposing forces pull it.
The tension force is applied along the whole length of the wire, pulling energy equally on both ends.
A horizontally pulling rope is dragging a box across the floor at a consistent speed. Friction is significant.
Hence, the force acting on the box will be weight W, Normal force N, and the tension force T, in the string.
