Consider the case where m1 and m2 are both non-zero, and m2> m1. let t1 be the magnitude of the tension in the rope connected to the block of mass m1, and let t2 be the magnitude of the tension in the rope connected to the block of mass m2. which of the following statements is true?
(a)-t1 is always equal to t2.
(b)-t2 is greater than t1 by an amount independent of velocity.
(c)-t2 is greater than t1 but the difference decreases as the blocks increase in velocity.
(d)-there is not enough information to determine the relationship between t1 and t2.

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?
