Answer:
Lightning
Explanation:
Air is a non-conductor of electricity because it does not have free electrons to carry the current. But when there is a high voltage, as in the case of lightning, the molecules of air get ionized and electrons are available to flow to make the current and conduct electricity through the air.
Answer: The wave is traveling in the - x direction.
Explanation: The parameter in a wave function determines the direction of the wave is "ωt"
Where ω = angular frequency(in hertz ) and t = time taken (in seconds)
The product of ωt = 2π which is angular displacement in radian.
A negative value of the of ωt means the wave is traveling in the negative direction.
Also a positive value of sin ωt means the wave is traveling in the positive direction
Solid and liquids are much more denser than gas because their molecules are close to each other and with that the molecules of them can't move that freely unlike the gas molecules. Also, because of being near to each other the molecules of solid and liquids became heavy making them dense.
