PRELAB QUESTIONS1. Looking down from a stationary tree branch, a merry-go-round spins in a counter-clock-wise direction with an angular velocity of 1 radian per second. A squirrel of mass 0.6kg sits on the outer rim of the merry-go-round, at a radius of 4.0meters. a)What is the magnitude and direction of the vector ?b) What is the magnitude and direction of the Coriolis pseudo-force as felt bythe squir-rel?c) What is the magnitude and direction of the centrifugal pseudo-force as felt bythe squirrel?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
