Astone is dropped from the top of kutub minar .it takes 3.84 seconds to reach the ground. calculate the height of kutub minar.( take g = 9.8m/s2)

Explanation:

By equation of motion

Here;

S = Kutub Minar's height which is unknown

u = initial velocity = 0

a= g= 9.8   m/s2

t = time=3.84sec

By substituting the values and since u=0 then

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
