Question 2 (5 points) Evidence gathered by studying the composition and movement of distant
galaxies indicates that the universe expanded rapidly from a single small
point. The universe has continued to expand for over 13 billion years.
Which statement is in agreement with the current understanding of the
expanding universe?

A) All matter and energy were contained inside the small point.

B) Matter and energy came from dark areas of the universe and were attracted to the small point.

C) Matter and energy fell into the small point the same way a black hole attracts matter and energy

D) Matter was condensed into a single point until energy was attracted to the matter from dark areas of the universe.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
