In the arctic, caribou and musk ox eat different kinds of plants, but the plants they eat typically grow in the same area. therefore, these two species often require the same space in which to feed. in one part of the arctic, caribou numbers have decreased and musk ox numbers have increased. which best summarizes this scenario?

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
