A police car’s radar gun emits microwaves with a frequency of f1 = 8.20 GHz. The beam reflects from a speeding car, which is moving toward the police car at 46.4 m/s with respect to the police car. The speeder’s radar detector detects the microwave at a frequency f2. A) How can you compare the two frequencies f1 and f2? B) Find the frequency difference f2 − f1 in kilohertz.
2. A satellite orbiting the Earth is powered by photovoltaic ("solar") panels that convert light energy to electricity with a conversion rate of 15.0%. Telemetry from the satellite indicates that the panels are supplying a peak power output of 3.60 kW, and the specifications of the panels state that they have 16 m² of light-collecting surface area. The radius of the Sun and its distance from Earth have long been known to be 6.96 × 108 m and 1.50 × 10¹¹ m, respectively. Assume the Sun radiates approximately as a blackbody and calculate the surface temperature of the Sun.
