The superheroine Xanaxa, with a mass of 67.9 kg, is in a hair–raising chase after the 71.7 kg archvillain Lexlax. She leaps from the ground to the top of a 163 m high building, then dives off and comes to rest at the bottom of a 15.9 m deep excavation, where she finds Lexlax and neutralizes him. Does all this bring about a net gain or a net loss of gravitational potential energy? loss gain What is the value of the net gain or net loss? Answer with a positive number. Assume g = 9.8 m/s 2 . net change in potential energy: J

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
