Answer:
D
Explanation:
D) The overall work done by gravity is zero
This statement is correct .
If m be the mass of each of the children and h be the height of tower
work done by gravity on the boys in going up = - mgh
it is so because force applied by gravity = mg downwards and displacement
is upwards
work done will be negative = - mgh
Work done by gravity on boys when they come down = + mgh because both force and displacement are downwards .
Hence total work done = - mgh + mgh = 0.
The children will have same kinetic energy as the inclined surface is friction-less so no energy will be dissipated hence addition of energy to boys in both the cases will be same.
Answer:
The types of reflection are; specular and diffuse. This depends on the fine or smooth nature of the surface where reflection occurs.
A mirror has a smoother surface than that of a yellow vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes the solid yellow vase.
Explanation:
Reflection is one of the properties of light waves which can be observed when light strikes a smooth plane surface. It is the throwing of light back through its initial path. In reflection, the angle of incidence is equal to the angle of reflection.
There are two types of reflection; specular and diffuse. Specular reflection occurs when light rays are reflected from a fine smooth surface, while diffuse reflection is observed when light rays are reflected in all directions due to the rough nature of the surface. Comparing the surfaces of a mirror and vase, that of a mirror is smoother than that of a vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes a solid yellow vase.
Answer:
D.) Blue
Explanation:
because Blue is a higher frequency and therefore corresponds to a higher energy level transition.
