Answer:
Blue light
Explanation:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves.
Answer:
* energy is proportional to masses. in a graph it would look like a line
* kinetic energy varies with the square of the velocity, In a graph it gives rise to a quadratic curve
Explanation:
Kinetic energy is defined by
K = ½ m v²
when analyzing this expression we can see:
* energy is proportional to masses. Therefore, doubling the mass doubles the kinetic energy and if the mass rises 4 times the energy rises 4 times, that is, they are directly proportional, in a graph it would look like a line
* kinetic energy varies with the square of the velocity. Therefore by doubling the speed the energy goes up 4 times. In a graph it gives rise to a quadratic curve
Answer: Worm
A virus spreads from one machine to another rapidly without human action. A virus is like a code that runes automatically without any knowledge or without taking permission of the user. It hampers the way a machine works. When a machine is attached to another machine directly or indirectly containing virus, it spreads itself. A worm is a kind of virus that can spread with zero human intervention. A virus still requires a human to download a contaminated file but worm does not. a worm can spread on its own
