We know, 1 m/s = 3.6 Km/h
So, 45 Km/h = 45/3.6 = 12.5 m/s
In short, It would be equal to 12.5 m/s
Hope this helps!
Answer:
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Explanation:
Given;
wavelength = 6.33 x 10^-7 m
Speed of light v = 3.0 x 10^8 m/s.
Frequency of the laser light f
= speed of light/wavelength
Substituting the given values;
f = 3.0 x 10^8 m/s ÷ 6.33 x 10^-7 m
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Rutherford's nuclear model stated that a cloud of negative electrons surround the nucleus however scientists realized that electrons in a cloud around the nucleus of an atom would be attracted to the nucleus, causing the atom to collapse. Thus Bohr's model proposed that electrons were contained in shells and they orbit the nucleus at fixed distances.
