A dog walks 12 meters to the east and then 16 meters back to the west. For this motion, what is the distance the dog moved? m (answers should be rounded to the nearest tenth - Example: 0.1, 1.5, or 5.0) What is the magnitude and direction of the displacement? Magnitude: m (round answer to the nearest tenth) Direction (N, S, E, W, NE, NW, SE, SW):

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
