2. The gravitational force between two objects (mass1 = 14 kg, mass2 = 7 kg) is measured when the objects are 20 centimeters apart. If the distance between them is increased to 40 centimeters, how does the new gravitational attraction compare to the first one that was measured?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

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

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
