Given two displacement vectors a → = (3.00 i ^ − 4.00 j ^ + 4.00k ^ )m and b → = (2.00 i ^ + 3.00 j ^ − 7.00k ^ )m , find the displacements and their magnitudes for (a) c → = a → + b → and (b) d → = 2 a → − b → .

A2 µc charge q1 and a 2 µc charge q2 are 0.3 m from the x-axis. a 4 µc charge q3 is 0.4 m from the y-axis. the distances d13 and d23 are 0.5 m. find the magnitude and direction of the resulting vector r. round your answer to the nearest tenth.

Which feature indicates that mars resides in the inner region of the solar system

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.
