A coin is placed in an empty beaker. When a transparent liquid is poured into the beaker, the apparent depth of the coin is found to be 40% less than the real depth. What is the refractive index of the liquid? The options for the answer are 0.4 / 0.6 / 1.2 / 1.7

A12-kg bag of groceries is tossed onto a table at 4.0 m/s and slides to a stop in 2.2 s . modify the equation fδt=δ (mv) to find the force of friction.

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

Can you match these to the correct definition
