Objects with masses of 149 kg and 1/3 kg are separated by 0.332 m. A 51.6 kg mass is
placed midway between them.
PART 1: Find the magnitude of the net gravitational
force exerted by the two larger masses on the
51.6 kg mass. The value of the universal gravi-
tational constant is 6.672 x 10-11 N. m2/kg2.
Answer in units of N. PART 2: leaving the distance between the 149 kg and the 773 kg masses fixed at what distance from the 773 kg mass (other than infinitely remote ones) does the 51.6kg mass experience a net force of zero? Answer in units of m.

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?
