Scientific knowledge is built as people come up with hypotheses and theories, repeatedly check them against observations of the natural world and continue to refine those explanations based on new ideas and observations.
Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??
2400/600 = 4hours.
Do this for all three and add up the hours.
Total time: 12 hours
Average speed is the total distance / total time.
So,
Add up all the distances and divide by 12.
(2400+1200+2500) / 12
Average speed: 508.33333333 km/h
Answer:
λ = 1.86 x 10⁻⁴ m = 186 μm
Explanation:
The relationship between the wavelength and the frequency of a wave is given by the following equation:
where,
λ = wavelength of infrared radiation = ?
c = speed of infrared radiation = speed of light = 3 x 10⁸ m/s
f = frequency of infrared radiation = 1.61 THz = 1.61 x 10¹² Hz
Therefore,
<u>λ = 1.86 x 10⁻⁴ m = 186 μm</u>
Force your doing it purposely and acceleration it’s just happening
The redshirting of the spectra of distant galaxies. They are moving away from us at a rate proportional to their distance
