A car is driving with a constant velocity at 35 m/s. How long, in seconds, must it drive to travel 630 meters?

The best answer i can think of is b

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Answer a descending mass of air will have its temperature increase because of the pressure exerted on it, because its temperature increases it will also be able to hold more water and feel drier;
