A turntable with a moment of inertia of 7.2 Γ β β rotates freely with an angular speed of 6.5 β . Riding on the rim of the turntable, 2 from the center, is a hamster. When the hamster walks to the center of the turntable, the angular speed of the turntable becomes β. What is the mass of hamster?

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.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earthβs geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earthβs field would have little effect on the bacteria. take the earthβs field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
