Arunner starts from a rest and speeds up with a constant acceleration . if she has gone a distance of 30 m at the point when she reaches a speed of 8 m/s what is her acceleration

Explanation:

As we know that the runner starts from rest position

So here we can say

now the distance moved by the runner is given as

also we know that final speed of the runner will be

now we know that

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.​
