1) A block of mass m is held stationary on a ramp by the frictional force on it from the ramp. A force F, directed up the ramp, is then applied to the block and gradually increased in magnitude from zero. Sketch the friction force as a function of time. Hint: be careful about the signs! 2) A

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
