Abullet is dropped from the same height when another bullet is fired horizontally they will hit the ground

At the same time.

Explanation:

In the first case ,

intial velocity = 0

displacement = -h

acceleration = -g

Using second equation of motion,

s = ut + .5a

- h = - 0.5g

t =

In the second case, consider only motion along y axis,

intial velocity = 0 ( all the velocity is along x axis)

displacement = -h ( height is same in both cases)

acceleration = -g

Using second equation of motion,

s = ut + .5a

- h = - 0.5g

t =

In both cases time is same.

Hence, they will reach the ground simultaneously.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;
