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:
at the Equator
Explanation:
The four seasons are determined by four main positions in the Earth's orbit in its turn around the Sun (ecliptic plane), which are called solstices and equinoxes: winter solstice (Capricorn point, December 22), spring equinox (Aries point, around March 21-22), summer solstice (Cancer point, June 21) and autumn equinox (Libra point, around September 22-23).
In the equinoxes, the axis of rotation of the Earth is perpendicular to the sun's rays, which fall vertically over the equator. In solstices, the axis is inclined 23.5º, so that the sun's rays fall vertically on the Tropic of Cancer (summer in the northern hemisphere) or Capricorn (summer in the southern hemisphere).
When falling vertically on Ecuador, it generates a greater impact on the surface of the Tierre reaching a greater amount of energy and therefore UV rays.

Hello some parts of your question is missing below is missing part
In order to satisfy as many wants as possible, it is necessary to achieve productive efficiency
(multiple choice)
because otherwise resources are idle.
because producing more of one thing also leads to producing more of another.
because otherwise output may go to where it is less valued.
answer : because otherwise resources are idle.
Explanation:
In order to satisfy as many wants as possible it is necessary to achieve productive efficiency and productive efficiency is when resources are used to its full potential to manufacture a product or service and during this process very few resources will be left idle. also when productive efficiency is achieved ; marginal cost = average cost of the manufacturing
