Answer 1

Explanation:

It depends on weight of object

It this condition you may observe

Firstly=>iron then wood and then wax

It happens due to buoyant force by air

But if there is no aur that is vacuum they will teach earth surface at same time

.....

Answer 2

ANSWER :-

CASE 1 :-

(considering air resistance)

Since , objects will in free fall so vertical resistance will occur as well as horizontal resistance (bcoz of flow in air) which does not affect the time of flight of objects. Since air resistance is inversely proportional to mass therefore , firstly iron will hit the ground then wood then wax.

CASE 2 :-

(without considering air resistance)

If air resistance is not considered, then all the masses in free fall falls with a acceleration of 10 m/s^2 , so, all three objects will fall on the ground at same time , no matter what is height and mass of the given objects.
