A nail rusting is an example of chemical change as the iron is oxidized to become rust. This is not a physical change.
Answer:
The wavelength is
Explanation:
Given that,
Speed
Mass of proton
We need to calculate the wavelength
Using formula of de Broglie wavelength
Put the value into the formula
Hence, The wavelength is
Streams of glowing gas that shoot out from the sun is called Prominence. It is a loop of incandescent, cool gas that extends way above the sun's edge can be viewed from Earth. These streams usually follow the magnetic field lines that are curved from an area of on magnetic polarity to an area of the opposite magnetic polarity. These streams can last for hour or even weeks.
Answer:
139.11 m/s
0.000194287 Hz
5147.00596 s
Explanation:
= Wavelength = 716 km
s = Distance = 3130 km
t = Time = 6.25 h
Speed is given by
Speed of the wave is 139.11 m/s
Frequency is given by
The frequency is 0.000194287 Hz
Period is given by
The period is 5147.00596 s
