For problems that involve an object accelerating along an inclined plane, how can the weight be used to determine the force component that causes motion? a, the weight is the full force that acts perpendicular to the surface of the ramp. b, the weight times the cosine of the ramp’s angle is the force perpendicular to the ramp. c, the weight times the sine of the angle of the ramp acts down along the ramp. d, the weight times the cosine of the angle of the ramp acts down along the ramp

relative to the ground, we can tell that the weight can be resolved into two components. The first component of this force is the normal force. The other component is along the incline and it is what is responsible for the objects acceleration. The angle between the weight vector and the normal component is 
, then , by trigonometry, the magnitude of the weight along the incline is 
.

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?
