- Hi! I didn't really understand the first answer I got for this... Hoping someone else can help? Thank you so much!The earth spins on its axis once a day and orbits the sun once a year. Determine the average angular velocity of the earth as it spins on its axis and orbits the sun. In each case take the positive direction for the angular displacement to be the direction of the earths motionMars is about twice as far from the sun as Venus. A Martian year, which is the time it takes Mars to go around the sun, is about 3 times as long as a Venusian year. a) Draw a sketch of the scenario, including the given information. b) Use your sketch to determine which of these two planets has the greater rotational speed in its orbit? and b) Which planet has the greater linear speed?

How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°, 30 rad, and 30 rev, respectively? 30° m 30 rad m 30 rev mSuppose that Earth's polar ice caps melted and the water returned to the oceans, so that the oceans were deeper by about 15.1 m. What effect would this have on Earth's rotation? Make an estimate of the resulting change in the length of the day. (Concern has been expressed that warming of the atmosphere resulting from industrial pollution could cause the ice caps to melt.)
