the unit talks about various astronomical tools, but satellites don't make the list-why? explain how satellites help us learn more about earth from space and analyze whether they can also help us learn more about space.

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

Most short-period comets do not have randomly oriented orbits because
