How does the theory of plate tectonics help explain the location and size of the Himalayan mountains?
O A. They formed along a boundary where two continental plates collide and push the land upwards.
OB. They formed along a ridge where tectonic activity produces volcanoes which erupt and grow taller.
OC. They formed where two plates pull apart and produce new crust which increases the elevation of the old crust.
O D. They formed where one plate is moving under another plate and sea level drops which makes the mountains taller.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
