- Assume that the solar wind causes the Sun to lose mass at a rate of 2 x 10’ kg/s. If you assume the wind is emitted a constant rate, estimate the time (in units of Gyr =Gigayears = 10° years) that it will take the entire Sun to evaporate via its solar wind emission. (Of course, the rate won't be constant throughout the lifetime of the Sun---this is just a rough estimate to understand the timescale associated with this process.) [Hint: you need to look up a number and do several unit conversions; this is a *rate* problem. Enter your answer as an integer or decimal, NOT in scientific notation.]Why are observers more likey to see aurorae in Canada than in Florida ?Use Stefan's law to calculate how much energy is emitted per unit area by the photosphere of sun 5800-K.
- The density and temperature in the solar corona are much higher than in the photosphere. (T/F)This picture shows a radio meter. It is designed to be placed in a sunny window. One side of each thin blade of the radio meter is painted black, and the other side is painted white. The suns rays strike the blades, in the device begins to spin. The device is powered by which kind of energy?(2009)
