Question

Because Venus has a very feeble magnetic field, the solar wind collides with its atmosphere, instead of being deflected by magnetic forces. Suppose that if a solar wind particle strikes the atmosphere of Venus, all its kinetic energy will be absorbed.

(a) What is the rate, in watts, at which Venus absorbs energy from the solar
wind? Assume that the energy density of the solar wind is
1
= 2 x 10 ºJm ³,

If a nonhuman civilization were to develop on Saturn's largest moon, Titan, its scientists might well devise a temperature scale based on the properties of methane, which is much more abundant on the surface than water is. Methane freezes at -182.6 °C on Titan, and boils at -155.2 °C. Taking the boiling point of methane as 100.0 °M (degrees Methane) and its freezing point as 0 °M, what temperature on the Methane scale corresponds to the boiling point of water on the Celsius scale, 100 °C? You must show all of the conversion steps.
