Answer:
The light rays falling on a rough surface does follow the laws of reflection. The light rays are incident parallel on the rough surface but due to uneven surface the light rays are not reflected parallel rather they are reflected in different direction. Hence, no image is formed.
Answer:
Although the core and mantle are about equal in thickness, the core actually forms only 15 percent of the Earth's volume, whereas the mantle occupies 84 percent. The crust makes up the remaining 1 percent.
Answer:
6.633s
Explanation:
For this equation we use the following kinematic equation:
^D = Vi(t)+(1/2)(a)(t)^2
88m-0m = 0m/s(t)+(0.5)(4m/s^2)(t)^2
88m = 2m/s^2(t^2)
t^2 = 44s
t = sqrt(44)
t = 6.633s
