Answer:
Explanation:
Option C is the correct answer
Answer:
f = 5.63 x 10¹⁴ Hz
Explanation:
Given,
speed of light, c = 3 x 10⁸ m/s
wavelength,λ = 533 n m = 5.33 x 10⁻⁷ m
frequency, f = ?
using formula of frequency
c is the speed of light
f = 5.63 x 10¹⁴ Hz
hence, the frequency of the light is equal to f = 5.63 x 10¹⁴ Hz

depends on its mass and speed.</span>
When 'The big bang' happened lots of large pieces of molten rock was flying around the solar system. As the rocks crashed together they got bigger and as the got bigger they attracted more rocks. Some scientists think that a large piece of molten rock hit the still developing Earth and created the Moon. This impact also caused the Earths angled spin. The Moon got trapped in Earth's orbit and has stayed ever since. Small astroids have hit the Moon causing craters. The Earth doesn't get hit as much because of our thicker atmosphere. Hope this helps!
Should be -9.8m/s^2!!! The force of gravity is the only thing pushing it down!!
Hope I helped you out!!
