The lead female character in the movie Diamonds Are Forever is standing at the edge of an offshore oil rig. As she fires a gun, she is driven back over the edge and into the sea. Suppose the mass of a bullet is 0.017 kg and its velocity is +650 m/s. Her mass (including
the gun) is 51 kg. (a) What recoil velocity does she acquire in response to a single shot from a stationary position, assuming that no
external force keeps her in place? (b) Under the same assumption, what would be her recoil velocity if, instead, she shoots a blank
cartridge that ejects a mass of 5.0 x 10kg at a velocity of +650 m/s?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

What are the dimensions of the cross section that passes through the points a, f, g, and d?
