1) Using the distance from the Sun to the Earth in meters, calculate its brightness on the
Earth in W/m^2. Use the formula Brightness= Luminosity/(Area of the Sphere)
2) Using the same method as in step 1, calculate the brightness of the Sun in Mercury.
3) Using the formula for the magnitude difference − = . (), what is the
difference of magnitudes of the Sun between the Earth and Mercury? (use the log function of your calculator).
4) Does the sun have a higher or lower apparent magnitude on the Earth than in Mercury? Explain your answer.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
