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.

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
