Asolid cylinder with a mass of 266 kg and radius 0.070 m is rotating with an angular speed of 83.0 rad/s about an axis passing through its center and perpendicular to its end faces. the rotation of the cylinder is slowed down by a factor of 5 by applying a tangential frictional force to it for 4.90 s. what is the magnitude, in n, of the friction force applied to the cylinder?

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?

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
