In a cyclic process, heat transfers are + 14.7 kJ, – 25.2 kJ, – 3.56 kJ and + 31.5 kJ. What is the net work for this cyclic process ?

A tree is subject to three forces as follows: 25 N pushing west, 10 N pushing
south (due to the slope it is growing on) and a third force of unknown magnitude and
direction (due to being tied to a stake to prevent it falling). What must the magnitude
and direction of the third force be in order that the tree experiences no net
acceleration?

State Newton’s three laws of motion, in each case give and explain an
example from agriculture that is directly related to each law

A gas is compressed from 5 L to 3 L under an average pressure of 200000 Pa. During the compression 0.3 kJ of heat is given off. The internal energy of the gas

In a certain gas system, the pressure remains constant at 150 kPa even though 1000 J of heat is added. The volume change is 1.8 L. How much does the internal energy in joules of the system change.
