When the initial speed given is 7.5m/s at an angle of 27° , ball will go
4.637 meters.
Assume no air opposition to the ball ;
Vertical component of ball is sin 27° = 0.453
0.453* 7.5 = 3.404 meters /sec
Time taken to reach ground is :
3.404 = -3.404+9.8*t
t= 6.808/9.8= 0.694 sec
Horizontal component is 7.5*cos27°= 6.682m/s
Distance = speed * time
=6.682 * 0.694
=4.637 meters
Horizontal distance it can cover in 0.694 sec is 4.637 meters
So range of ball is 4.637 meters.
Form of motion experienced by an object or particle that is projected near surface of the earth and moves along a curve is called Projectile motion. Three types of projectile motion are Horizontal projectile motion. Oblique projectile motion and Projectile motion on an inclined plane.

Answer: a. oxidation
Explanation:
The weathering is a process through which the large rocks are broken into small rocks or pieces. The weathering can be caused by the physical and chemical agents.
The chemical weathering is a process in which the rock is disintegrated or broken into sub-components by the action of the chemical agents present in the surrounding of rock for example, air, water, acid, and alkali.
The air will cause the oxidation of the rocks. This will cause weathering of rocks as the oxygen will react with the minerals present in rocks making their bonds weak and causes disintegration of rocks.
