Answer:
sunburn is caused by too much exposure to ultraviolet rays.
Explanation:
Melanin is the dark pigment in the skin's outer layer that gives skin its normal color. When your skin face too much exposure to sun. UV rays in sun destroys the melanin due too which sunburn is caused
Answer:
For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.
Explanation:
- Light is the moving energy form that is made up of tiny particles known as photons.
- The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
- The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
- Similar to sound waves, light wave can interfere with each other.
The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.
The missing graphs are attached as image.
The average kinetic energy of gas molecules is

K∝T
So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.
Thus, option B is correct.
