Answer: 
Explanation:
The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is 
).
It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).
Now, if we were just in the North Pole, Polaris would by exactly over our heads (
over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of over the horizon.
Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is .
The apparent brightness is defined by how much light we get pretty much. The formula is:
This takes into account that the light is spreading out to a sphere that has the surface given by 4πd^2.
We have that d=20 ly and 1 ly is 9.46*10^12 km or 9.46*10^15m.
Hence, d=20*9.46*10^15=189.2 *10^15 m
Now, we can substitute the d value and calculate that L=<span>8.45184*
W/m^2</span>

I think if someone is wrong doing something innocent then you have to wrong do them to put an end to it. So when they say "forget their rights" you gotta say "forget their rights". It should be completely an eye for an eye in an incident such as this one. Fighting fire with fire will only burn everything down but thats exactly what you want to happen when it comes to a matter such as this one.</span>
Answer: to me personally I think They would become igneous rocks
Explanation:
If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.
- The temperature of the sun does not change the materials of the earth substantially.
- There is a very significant effect of the heat from the interior on rocks, especially sedimentary rocks.
- Heat can hit a whopping 6000 ° C from the inside, which is more than enough to cause a metamorphic shift in a rock in the body.
- Actually, the igneous rock will be formed from the sedimentary rock at this temperature.
The p<span>leistocene</span>is the most recent epoch of repeated glaciation on the earth.
-Hope this helps.
