Assume that the car at point a and the one at point e are traveling along circular paths that have the same radius. if the car at point a now moves twice as fast as the car at point e, how is the magnitude of its acceleration related to that of car e.

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
