Aperson listening to a siren from a stationary police car observes the frequency and wavelength of that sound. the car now drives rapidly away from the person.
o the wavelength of the sound the person observes will be shorter than it was, but the frequency will not be changed.
o the frequency of the sound the person observes will be higher than it was, but the wavelength will not be changed.
o the wavelength of the sound the person observes will be longer than it was, and the frequency will also be lower than it was.
o the wavelength of the sound the person observes will be shorter than it was, and the frequency will also be higher than it was.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
