In the last question, you thought about what it would be like to live on Mercury, and to observe Earth in an attempt to decide between the heliocentric and Mercury-centric models of the solar system. Now let's imagine the same scenario, if you lived on Jupiter. (Technically, you can't live on Jupiter, since it's made of gas and liquid, but let's pretend it had a solid surface you could stand on.) Someone suggests looking at Earth, to see how lit-up it can appear. Let's assume you have a telescope that can magnify Earth well enough to see any phases it might have. Would this work well, for trying to tell the difference between the heliocentric and Jupiter-centric models

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
