Which is a difference between the trade winds and the polar easterlies? The trade winds tend toward the right, and the polar easterlies tend toward the left.

The trade winds blow in the Northern Hemisphere, and the polar easterlies blow in the Southern Hemisphere.

The trade winds blow near the equator, and the polar easterlies blow near the poles.

The trade winds blow from west to east, and the polar easterlies blow from east to west.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
