Imagine that two balls, a basketball and a much larger exercise ball, are dropped from a parking garage. if both the mass and radius of the exercise ball are 3 times larger than the mass and radius of the basketball, which of the two balls do you think will reach the ground first?

Here if we assume that there is no air friction on both balls then we can say

now the acceleration is given as

so here both the balls will have same acceleration irrespective of size and mass

so we can say that to find out the time of fall of ball we can use

now from above equation we can say that time taken to hit the ground will be same for both balls and it is irrespective of its mass and size

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.​
