The world’s fastest elevator, in Taiwan’s Taipei 101 skyscraper, ascends at the rate of 1010 m/min. Counterweights balance the
weight of the elevator’s car, so the motor doesn’t have to lift the car’s
weight. If the motor produces 330 kW of power, what’s the
maximum number of 67-kg people the elevator can accommodate?
(Your answer somewhat overestimates the actual rated load of 24
people.)

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
