Question 14 of 20 A crate falling from a plane is part of a closed system that has 24,450 J of
mechanical energy. If the kinetic energy of the crate increases from 10,000 J
to 15,000 J, what happens to the gravitational potential energy of the system?
A. It decreases from 15,000 J to
10,000 J.
B. It increases from 10,000 J to
15,000 J.
C. It decreases from 14,450 J to
9,450 J.
D. It increases from 9,450 J to
14,450 J.

Select all the correct answers. which statements fail to meet the requirements of a scientific claim? a) in the final 100 meters of a 10,000-meter race, an athlete's speed is more strongly related to anaerobic efficiency than to aerobic efficiency. b) flowers that reflect the most ultraviolet light are more likely to attract bees and other pollinators than flowers that reflect less ultraviolet light. c) even though evidence indicates that the solar system's planets follow elliptical paths, copernicus's model involving circular orbits is true. d) the evidence supporting newton's laws of motion was accurate in newton's time, but the universe operates differently today.
