Acar traveling at 27.4 m/s hits a bridge abutment. a passenger in the car, who has a mass of 65.0 kg, moves forward a distance of 56.0 cm while being brought to rest by an inflated air bag. assuming that the force that stops the passenger is constant, what is the magnitude f of this force?

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.
