Aspacecraft is launched from earth toward the moon where will the spacecraft be when the gravitational forces acting on it are equal

a closer to earth than to the moon because the moon has greater mass than the earth

b closer to the moon because the moon greater mass than the earth

c closer to earth than to the moon because earth has greater mass

d closer to moon than earth because earth has a greater mass than the moon

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

Gunpowder residue is most likely to show up where on a shooters hands

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?
