The image above shows a block pulled across a table. The spring scale which measures in Newtons, reads the force resisting the motion known as friction force. In the image above, what would be a reasonable measurement of normal force if friction force
measured 80 Newtons?
A)
40 Newtons
B)
60 Newtons
70 Newtons
D)
140 Newtons

The momentum of an isolated system is conserved a) only in inelastic collisions. b) only in elastic collisions. c) in both elastic and inelastic collisions

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).

When using the scientist method, which step comes last?
