Miguel is skipping rocks across the surface of a lake. After he throws it, each stone goes through the following motions: the st
one moves toward the water the stone hits the surface of the water and bounces off gravity pulls the stone back toward the water the stone enters the water and slows down In which part of the stone's movement is the stone most like a beam of light that is being refracted?
- When light is refracted it speed is slowed down or increases depending on the medium it enters. This depends on the ratio of air-water refractive index ratio.
- The speed of an object in air is faster than speed of an object in water. Because the refractive index of air is less than that of water. In refraction, the light changes direction slightly because it slows down or speeds up, depending on what medium it is changing into.
- From this we could say as the rock enters the water and slows down it models as if the light has been refracted.
A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight.
b. Yes, the shape of the sheet will affect the Flux through it. This is because flux is dependent on area of the surface and the area is dependent on the shape of the surface.
Explanation: in order for something to accelerate it must speed up or slow down . When unequal forces react it casuse a change in motion which is also know as acceleration .
