A pear and a papaya are placed 12 meters apart from each other. The pear is 0.005 kg and the papaya is 0.008
kg. Calculate the force of gravitation between them.

The law of reflection states that the angle of reflection is equal to the angle of

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
