That's the <em><u>speed</u></em> of the wave.
("Velocity" is not a good way to say it, because 'velocity' always needs a direction,
and neither frequency nor wavelength tells anything about direction.)
Answer:
1. Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.
2. Well, Pluto was most likely difficult to find, because of its small size and great distance from Earth.
Answer: Longitudinal waves are the type of waves that cause sound.
Explanation:
There are two types of waves: Longitudinal waves and Transverse waves. Longitudinal Waves: A wave in which the particles of the medium vibrate back and forth in the 'same direction' in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal waves.
Given :
A map shows that a star is 25 light years away.
To Find :
If you get in a ship and travel to this star at 0.95c, How far will the ship need to travel to reach this star.
Solution :
We know, 1 light year in km is given by :
So, 25 light years is given by :
Hence, this is the required solution.
Answer:
D: The distance between the particles decreases
Explanation:
Taking away energy slows down molecules, like how you slow down when you are cold (I think)
