Blocks with masses of 3.0 kg, 4.0 kg, and 5.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 13 N force applied to the 3.0 kg block. How much force does the 4.0 kg block exert on the 5.0 kg block?

How are mass and weight related? a) Mass is weight multiplied by gravity b) Weight is an intrinsic property, mass is not c) Weight is mass multiplied by gravity d) Weight and mass are not related

10. Explain the difference between the short-term effects of concussions and some of the long-term effects that scientists are recently discovering.

Like the polar bear, the walrus is a strong swimmer, although it does not have the same endurance. For short periods of time, a walrus can swim at an average speed of 9.7 m/s. How far would a walrus swim at this speed in 3.4 minutes?

How did Einstein's and Newton's theories differ in terms of explaining the cause of gravity?
