B) made of lighter colored, younger rocks than the mare.
C) formed by plate tectonics, like the Earth's Himalayas.
D) formed by volcanic eruptions, much like our Andes.
E) brighter than the mare, since they are covered with reflective glass from the rays.

A 20.0 kg box slides down a 12.0 m long incline at an angle of 30.0 degrees with the horizontal. A force of 50.0 N is applied to the box to try to pull it up the incline. The applied force makes an angle of 10.00 degrees to the incline and above the incline. If the incline has a coefficient of kinetic friction of 0.100, then the increase in the kinetic energy of the box is
A. 203 J. B. 275 J. C. 300 J. D. 392 J. E. 425 J.
