David tied a ball to the end of a long string. Holding the end of the string, he swung the ball in a circle around him to model how Earth orbits the sun. He knows that the orbit of Earth depends upon the gravitational pull. Which component of David’s model illustrates the effect of gravity?

A) The ball

B) The string

C) The distance from David

D) The speed the ball revolves

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
