Copper has a density of 9g/cm3. If a piece of copper has a volume of 10cm3, what is its mass? Equation is density = mass divided by volume

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
