What is the threshold velocity vthreshold(water) (i. e., the minimum velocity) for creating Cherenkov light from a charged particle as it travels through water (which has an index of refraction of n

Avalue that describes how heavy an object is and is related to the force of gravity is

Determine the maximum r-value of the polar equation r =3+3 cos 0

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
