Suppose one Ewok is standing on Earth and another is on the Moon. The Moon is in the first quarter phase (as seen from the Earth). The Sun is directly overhead as seen by both Ewoks. If the Ewoks both have fantastic telescopes, can they see each other wave at the other? T/F?

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
