Satellites are objects which orbit the planet. The natural satellite of Earth, in this case, is moon
Answer: 15.6 metres
Explanation:
Given that:
length of wave (λ)= ?
Frequency of wave F = 28 Hertz
Speed of wave (V) = 437 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply V = F λ
Make λ the subject formula
λ = V / F
λ = 437 m/s / 28 Hertz
λ = 15.6 m
Thus, the length of the wave is 15.6 metres

Answer:
Explained
Explanation:
Planets orbits around in an elliptical shape. In that shape sometimes they are closer to the star and sometimes far away from it.
When the planet is closer to the star it experiences a greater gravitational pull, hence greater velocity, and when it is far from star it experiences a lesser pull, hence slower speed. So, the area that the planet sweeps is equal in both cases. because when it speeds up the length covered along the orbital path is greater, but it is also closer to the star, and that dimension is decreased.
The triangle mention in the question is of variable size, its height increases when the planet is far and its base in increases when the planet is near the star. Hence, the area remains constant throughout.
