The piece of evidence that suggests that the inner planets were formed from the same rotating cloud of gas and dust is that the planets orbit the sun in the same direction and in the same plane
Smaller planets like Mercury, Venus, Earth, and Mars are considered inner planets. Mercury is thought to be the smallest inner planet, with Earth being the largest. The vastly larger outer planets, such as Jupiter, Saturn, Uranus, and Neptune, are the opposite.
A route that an object or planet in space follows around another body is referred to as an orbit. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.

In order to answer this, you can use this formula :
F = m.a
which means
a = F/m
a = 18N / 2kg
a = 9 N/kg or 9m/s2

Photon has no rest mass but when photon travels at the speed of light, it gains momentum.
The energy of the photon is E= pc, c = speed of the photon and p= its momentum.
∴ E = pc
but p = h/λ (This comes from De-broglie's theory)
∴ E = hc/λ
frequency = ν = c/λ
∴E = hν
