Numerical Response 1 A space probe was launched to perform a surface study of Venus. The probe's average distance from the centre of Venus was 6.79 x 109m. The mass of Venus is 4.88 x 1024 kg. The average gravitational field strength of Venus at the probe's location is N/kg.

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.
