Heya!!
For calculate frequency, lets applicate formula:
<u>Δ Being Δ</u>
f = Frequency = ?
v = Velocity = 144 m/s
= Wavelenght = 0,5 m
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The frequency of that wave is <u>288 Hertz</u>
Good Luck!!
It would be air friction, which is what’s holding the aeroplane back, and engine thrust, which is powering the aeroplane forward. Hope this helps!
I would say unlimited polarity because the compass’s needle is always attracted to Earth’s north pole.
Good luck to you!
Yes, a shape of a molecule does matter.
The shape of a molecule helps to determine its properties.
For example, water molecules have a bent structure. This is one reason why water molecules are polar and have properties such as cohesion, surface tension and hydrogen bonding.
I hope this helps!
