Consider a PV-diagram in which the path followed by one mole of perfect gas a cylindrical container is shown in (fig.). Given to internal enregy for one mole of gas at temperature T is (3 // 2) RT,find the heat supplied to the gas when it is taken from state 1 to 2,with V_2=2V_2 .

Consider a PV-diagram in which the path followed by one mole of perfect gas a cylindrical container is shown in (fig.). Find the work done when the gs is taken from state 1 to state 2.

An archer stretches her bow while taking aim at the target. She then releases the arrow, which begins to move towards the target .Based on this informaion, fill up the gaps in the following statements using the following terms. Muscular,contact,non -contact,gravity, friction,shape, attraction While the arrow moves towards its target, the forces acting on it are due to................ of air.
