The energy of a photon is given by:
where h is the Planck constant and f is the photon frequency.
We know the energy of the photon,
, so we can rearrange the equation to calculate the frequency of the photon:
And now we can use the following relationship between frequency f, wavelength
and speed of light c to find the wavelength of the photon:
The cells in your body help get oxygen to cellular respiration.
The third one sliding friction
Explanation:
Answer:
Abiotic - sun Biotic- Plants
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Abiotic means non living so the sun is non living. The sun gives us warmth and the ability to survive
Biotic means alive or living- plants are living and give off oxygen and take in carbon to help us live umm ok
The gravitational forces between the Earth and Moon are greatest when the two bodies are closest together. That happens every 27.32 days, when the Moon is at the perigee of its orbit.
Even if this happened at the same time in every orbit, the date would change, because there are not 27.32 days in a month.
But it doesn't happen at the same time in every orbit ... the Moon's perigee precesses around its orbit, on account of the gravitational forces toward the Earth, the Sun, Venus, Mars, and the other planets.
