The wavelength and frequencyincrease (decrease) in proportion to energy levels. Short wavelengths have a higher energy than long wavelengths because of the link between wavelength and frequency, which dictates that the higher the frequency, the shorter the wavelength.
Energy is defined as the capacity of a physical system to perform work.
Wavelength is related to energy and frequency by
E = hν = hc/λ,
where E = energy, h = Planck's constant, ν = frequency, c = the speed of light, and λ = wavelength
The number of waves that pass a specific place in a predetermined period of time is known as the wave frequency. The hertz is the wave frequency SI unit (Hz)
The distance between two successive crests or troughs of a wave is known as its wavelength. It is calculated using the wave's direction.

The positive and negative electrons split in the cloud
Positive going to the bottom of the cloud and negative to the top.
Since you are made of negative electrons, you attract the positive electrons to you causing you to get struck by lightning.
The ground has negative electrons too!
This will shock the ground and end up shocking you as well, since the ground and you are connected.
Lightning and thunder are connected! They do happen at the same time. The reason why the thunder travels later than the lightning is because you are away from the lightning and the sound waves are just getting near you
B.) How are thunderstorms dangerous?
Thunderstorms are dangerous because they give off positive energy. If you are standing outside while a thunderstorm is in session, you could get shocked since you are made of negative energy and attract positive energy.
If your hair is sticking straight up, you are about to be struck by lightning. Crouch down and cover your head next to your ears and prepare for impact.
You might ask, "Why can't I just run from the lightning?" That is true, but since you aren't faster than light itself, you will still wind up caught in the storm.
Avoid this by staying inside.

A) equal
B) half as much
C) twice as much
D) four times as much
Answer: C
Explanation:
Calculate EkA -kinetic energy of car A
m=1000kg
Va=16.66 m/s
EkA=m*Va²/2
Eka=(1000kg*277.556m²/s²)/2
Eka=138 777.8 J
Calculate kinetic energy of CarB:
m=2000 kg
Vb=8.33 m/s
Ekb=(m*Vb²)/2
Ekb=(2000kg*69.39m²/s²)/2
Ekb=69 388.9 J
compare Eka with EkB
Eka/Ekb=138 777.8 J/69 388.9
Eka/Ekb=2
The kinetic energy of car A is twice as much as that of car B. This is calculated using the formula for kinetic energy, which is 1/2 * mass * (velocity)^2.
To compare the kinetic energy of car A with that of car B, we first need to understand the mathematical formula for kinetic energy, which is 1/2 * mass * (velocity)^2.
Let's calculate for each car:
Therefore, car A has twice as much kinetic energy as car B.
