Two ice skaters are at rest and facing each other. In order to move, they push off each other. What is known about their final total momentum? A. Nothing is known about the final total momentum.
B. One skater must remain at rest.
C. The final total momentum must equal zero.
D. Since they are on ice, this will not work. Neither can move.

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

The energy produced as a result of this flow of electrons from atom to atom is called

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
