The key thing we look for is <u>WATER.</u> We need to analyze whether a world is a possible home to life if it has the past, present, and future existence of liquid water.
Even if the planet has evidence of atmospheric oxygen, it is still insufficient for humans to live in it if it lacks H2O.
Some may argue that the presence of organic molecules such as amino acids should also be taken into account. Even if they have a valid point, it is not the most significant factor that we consider when deciding if the world is a possible home for life.
Aside from water, the world's surface color changes that indicate vegetative growth can be critical in ensuring that the world is habitable. However, vegetative growth is insufficient to be significant if the planet lacks a consistent source of water.
The first confirmed Earth-size planet where liquid water might accumulate on the surface is Kepler-186f. The discovery of another world provides evidence that there are planets in other stars' habitable zones.

Answer:
The speed and direction of the two players immediately after the tackle are 3.3 m/s and 53.4° South of West
Explanation:
given information:
mass of fullback,
= 92 kg
speed of full back,
= 5.8 to south
mass of lineman,
=110 kg
speed of lineman,
= 3.6
according to conservation energy,
assume that the collision is perfectly inelastic, thus
initial momentum = final momentum
=
'
m₁v₁ = (m₁+m₂)
'
' = m₁v₁/(m₁+m₂)
= (92) (5.8)/(92+110)
= 2.64 m/s
=
'
m₂v₂ = (m₁+m₂)
'
' = m₁v₁/(m₁+m₂)
= (110) (3.6)/(92+110)
= 1.96 m/s
thus,
' = √
'²+
'²
= 3.3 m/s
then, the direction of the two players is
θ = 90 - tan⁻¹(
'/
')
= 90 - tan⁻¹(1.96/2.64)
= 53.4° South of West
1. Frequency: ![7.06\cdot 10^{14} Hz](https://tex.z-dn.net/?f=7.06%5Ccdot%2010%5E%7B14%7D%20Hz)
The frequency of a light wave is given by:
![f=\frac{c}{\lambda}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bc%7D%7B%5Clambda%7D)
where
is the speed of light
is the wavelength of the wave
In this problem, we have light with wavelength
![\lambda=425 nm=425\cdot 10^{-9} m](https://tex.z-dn.net/?f=%5Clambda%3D425%20nm%3D425%5Ccdot%2010%5E%7B-9%7D%20m)
Substituting into the equation, we find the frequency:
![f=\frac{c}{\lambda}=\frac{3\cdot 10^{-8} m/s}{425\cdot 10^{-9} m}=7.06\cdot 10^{14} Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bc%7D%7B%5Clambda%7D%3D%5Cfrac%7B3%5Ccdot%2010%5E%7B-8%7D%20m%2Fs%7D%7B425%5Ccdot%2010%5E%7B-9%7D%20m%7D%3D7.06%5Ccdot%2010%5E%7B14%7D%20Hz)
2. Period: ![1.42 \cdot 10^{-15}s](https://tex.z-dn.net/?f=1.42%20%5Ccdot%2010%5E%7B-15%7Ds)
The period of a wave is equal to the reciprocal of the frequency:
![T=\frac{1}{f}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf%7D)
The frequency of this light wave is
(found in the previous exercise), so the period is:
![T=\frac{1}{f}=\frac{1}{7.06\cdot 10^{14} Hz}=1.42\cdot 10^{-15} s](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7B7.06%5Ccdot%2010%5E%7B14%7D%20Hz%7D%3D1.42%5Ccdot%2010%5E%7B-15%7D%20s)
