The equation relating velocity and wavelength is written below:
v = λf
where λ is the wavelength in m while f is frequency in 1/s.
Let's determine first the frequency from the speed of light:
c = distance/time, where c is the speed of light equal to 3×10⁸ m/s
3×10⁸ m/s = (300 mm)(1 m/1000 mm)/ time
time = 1×10⁻⁹ seconds
Since f = 1/t,
f = 1/1×10⁻⁹ seconds = 10⁹ s⁻¹
Thus,
v = (795×10⁻⁹ m)(10⁹ s⁻¹)
v = 795 m/s
Liquids flow because its particles can move over each other. The particles have freedom to move and they will keep moving until it takes the shape of its container.
Solid particles are rigid and tightly packed, they cannot move, so it does not flow.
Answer:
false
Explanation:
The atom model has changed over time because of the discovery of subatomic particles
CO2 will be the first to boil because it will be the first to warm up because it is the closest temperature to 0
Answer:
Large-scale nuclear is fission a rare phenomenon on Earth because
atoms that undergo fission aren't concentrated enough to sustain a chain reaction.
