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


Answer:
The force that the book exerts down on the table is equal to the force the table exerts upward.
Explanation:
I am 100% positive. That results in balanced forces which is why it does not move. If you did want it to move, you would apply unbalanced forces.
Decreasing Pressure. The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.
