A 150g piece of ice falls off an icicle and falls into a lake. If the icicle has a volume of 163 cm3 will the icicle sink or float?

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

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.

What is the moment of inertia i of this assembly about the axis through which it is pivoted? express the moment of inertia in terms of mr
