Suppose you place a coin on a book; the book’s cover acts as a ramp. You open the cover slowly until static friction is overcome. The coin begins to slide. What happens to the forces on the coin as the angle of the cover changes?

Ann walks 80 meters on a straight line 33 ∘ north of east starting at point 1. draw ann's path. represent ann's walk with a vector of length 80 meters. draw the vector starting at point 1. the length given in the display is in meters.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

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).
