The answer to this question is true
Answer:
The Electron
Explanation:
Electrons are how some atoms let electricity flow easily. If have closely bound electrons, then they are a bad conductor, or insulator. Atoms with loosely bound electrons allow electricity to easily flow, making these types of atoms great conductors. This is the case with most metals, where their electrons are very loose, making metals, like copper, great at transmitting electricity.
All we really need to know to answer this one is the speed of sound, and that's not easy. Sound has different speeds in wet air, dry air, warm air, cool air, and air at high or low pressure ... and ALL of these are present on the way from the thunderstorm to you !
So let's just use the number for the speed of sound in dry air at sea level and comfortable temperature: 343 meters/sec.
time = (distance) / (speed)
Time = (1485 meters) / (343 m/s)
Time = (1485/343) second
Time = 4.3 seconds roughly approximately around about
The period T of a pendulum is given by:
where L is the length of the pendulum while
is the gravitational acceleration.
In the pendulum of the problem, one complete vibration takes exactly 0.200 s, this means its period is
. Using this data, we can solve the previous formula to find L:
The answer is water because since water is used to make the rainbow so they are simillar hope this was helpful!!
