<span>This is an agrarian society, taken to its extreme. These societies are largely dependent upon farming and related activities as a way of earning income, and also for using the farmed items as a way of supporting oneself as food and clothing.</span>
Answer:
It looks yellow because that is the only (major) color reflected.
Visible spectra is from about 4000-7000 Angstroms (10^-10 m).
Red are longer wavelengths and blue are the shorter wavelengths.
The Sodium doublet (yellow) occurs around 5900 Angstroms.
To solve this problem it is necessary to apply the concepts related to the kinematic equations of movement description, which determine the velocity, such as the displacement of a particle as a function of time, that is to say
![v = \frac{x}{t}\rightarrow x = v*t](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bx%7D%7Bt%7D%5Crightarrow%20x%20%3D%20v%2At)
Where,
x = Displacement
v = Velocity
t = Time
Our values are given as,
![v=3*10^8m/s](https://tex.z-dn.net/?f=v%3D3%2A10%5E8m%2Fs)
![t = 1.33 s](https://tex.z-dn.net/?f=t%20%3D%201.33%20s)
Replacing we have that,
![x=v*t](https://tex.z-dn.net/?f=x%3Dv%2At)
![x=(3*10^8)(1.33)](https://tex.z-dn.net/?f=x%3D%283%2A10%5E8%29%281.33%29)
![x = 399'000.000m](https://tex.z-dn.net/?f=x%20%3D%20399%27000.000m)
Therefore the distance from Earth to the Moon is 399.000 km
Answer:
Height of tree = 78.35 meters.
Explanation:
We have
1 meter = 3.28 feet
That is
![1 ft = \frac{1}{3.28}=0.3048m](https://tex.z-dn.net/?f=1%20ft%20%3D%20%5Cfrac%7B1%7D%7B3.28%7D%3D0.3048m)
Here height of tree = 257 ft
Height of tree = 257 x 0.3048 = 78.35 m
Height of tree = 78.35 meters.
Answer:
Potential Energy to Kenetic Energy
Explanation:
When holding a ball in the air, the ball has potential energy. Once you drop the ball, the ball gains Kenetic Energy
