You can calculate an average if you know both the total distance and the total time of the trip. *

speed

Explanation:

Given: an incomplete sentence

To fill: the blank

Solution:

Speed is not a vector quantity but a scalar quantity as it has magnitude but no direction.

Speed = Distance ÷ Time

You can calculate an average speed if you know both the total distance and the total time of the trip.

Average speed = Total distance ÷ Total time

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
