A proton (mass m = 1.67 × 10-27 kg) is being accelerated along a straight line at 2.90 × 1013 m/s2 in a machine. If the proton has an initial speed of 2.00 × 105 m/s and travels 1.80 cm, what then is (a) its speed and (b) the increase in its kinetic energy?

True or false graphs must include scales that increase by the same amount

Which additional product balances the reaction h2so4 + 2naoh → na2so4 + 2h2o 2oh h2o2 h3o

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.
