Aplastic ball of mass 0.200 kg moves with a velocity of 0.30 m/s. this plastic ball collides with a second plastic ball of mass 0.100 kg that is moving along the same line at a velocity of 0.10 m/s. after the collision, the velocity of the 0.100 kg ball is 0.36 m/s. what is the velocity of the second ball?

Avoltage source vs = 10 v is in series with a resistor of 10 kohm. if the source transformation theorem is applied, what will the value of the current source be in ma ?

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?
