When light waves interfere the result is often a pattern of light and dark areas, like those shown above. The dark areas are caused by interference and the light areas are caused by interference.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
