A person pushes a shopping cart through the store a combined mass of the shopping cart plus groceries is 415.0 KG the coefficient of friction between the shopping cart in the floor is 0.7120 the shopping cart accelerates at a rate of 2.14 0M/S^2 determine the force applied to the shopping cart by the person pushing answer should have the correct number of significant figures and have the correct units

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?
