Answer:

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density).
<h3><em>when </em><em>a </em><em>light </em><em>ray </em><em>goes </em><em>from </em><em>a </em><em>medium </em><em>with </em><em>higher </em><em>refractive </em><em>index </em><em>to </em><em>a </em><em>medium </em><em>with </em><em>lower </em><em>refractive </em><em>index.</em><em>.</em><em> </em><em>it </em><em>gets </em><em>deviated </em><em>from </em><em>the </em><em>normal.</em></h3>
<h2><em>hence.</em><em>.</em><em>.</em><em> </em><em>the </em><em>statement</em><em> </em><em>is </em><em>true.</em><em>.</em><em>.</em></h2>

When you kick a ball the when your foot hits the ball the force from your foot is now on the ball and if the ball bumps into somoene they might fall(if you kick hard)
Answer:
The particle comes to rest before reaching the position x=4m.
Explanation:
When the object is at x=0m, all of its energy is kinetic energy. Using the equation for kinetic energy yields KE=1/2mv^2=(12)(2)(3)^2=9J. Using the given equation for potential energy when the object is at x=4m yields U=4x^2=4(4)^2=64J. Since the system only has 9J of energy, the object comes to rest before reaching x=4m.
Answer:
The work done will be 
Explanation:
The work equation is given by:

Where:
F is the force due to gravity (weight = mg)
x is the length of the ramp (3 m)
Now, the force acting here is the component of weight in the ramp direction, so it will be:

Therefore, the work done will be:
