Kepler's three laws of orbiting bodies contradicted the prevailing theory of the previous 1400 years (the geocentric theory of Claudius Ptolemy, c. 100-170 CE). Identify each of Kepler's laws by the simple summary statement:

The force will determine the acceleration.

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.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
