A Rod of length has a total charge uniformly distributed along its length. The rod lies along the axis with its center at the origin.

a. Find an expression for the electric potential as a function of position along the axis.
b. Show that the result obtained in Part (a) reduces to for Explain why this result is expected

Describe cytokinesis in plants and animals. in animals: in plants.

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.
