- A 12 g bullet is fired from a gun and moves vertically upwards at a velocity of 950m/s and strikes a 2kg brick which is originally at rest, as shown in the picture below. If the bullet emerges from the brick at a speed of 290m/s, determine 1. What is the The maximum height to which the brick rises? 2. What is The increase in the internal energy of the whole bullet-brick system? 290 m/s 950 m/sThe internal energy of the gas in a gasoline engines cylinder decreases by 160J. If 65.0 J of work is done by the gas, how much energy is transferred as heat? Is this energy added to or removed from the gas? Show procedure and the final answerA series of thermodynamic processes is shown in the pV-Diagram (see figure on the side). In process ab, 150J of heat are added to the system, and in process bd, 600 J of heat are added. Find a) internal energy change in process ab; b) the internal energy change in process abd; and c) the total heat added in process acd.

Explain your reasoning.Calculate the work done on the gas during the step from a to b and then answer the following question: Does energy enter or leave the gas in the form of work during this step? Explain. Calculate the heat transferred to the gas during the step from a to b and then answer the following question: Was the gas at a higher or lower temperature than the environment during this step? Explain. Calculate the change in internal energy of the gas from a to b.84 J of heat energy are transferred out of an ideal gas and 35 J of work is done on the gas. What is the change in thermal energy, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
