Answer:
5.099*10^14 m^2
Step-by-step explanation:
Earth is in thermal equilibrium. This means that our planet is radiating away exactly as much energy as it is receiving from the Sun. This "re-radiation" from the Earth is not visible because it its peak wavelength is in the infrared part of the spectrum. Even the coldest parts of the Earth are way above absolute zero, so every square meter of Earth’s surface is radiating this energy out to space. Using the same radius given in step 2 above, and the formula for the area of a sphere, calculate the surface area of the Earth.
(The radius of the Earth is 6,370,000 meters.)
The earth is spherical in shape , so we use the formula for finding the surface area of a sphere
Surface Area=
S.A=4*3.14*6,370,000^2
S.A=4*pi*40576900000000
S.A=5.099*10^14m^2
Man occupies about one-eighth of the earth.
There are 87600 hours in a decade
I'm not sure your question has enough information to be answered properly, but I'll try to help:
Assuming each of them are sweeping 1/2 of the garge, we're gonna cut each of their times in half.
Now the girl needs 10 minutes for half the garage and her brother needs 15 minutes.
So, if they work together, the first ten minutes will overlap each other while the girls brother gets left behind to finish up for an extra five minutes.
So, when working together, the boy and the girl need 15 minutes to sweep the garage.
Answer:
Plane MNO
Plane PST
Step-by-step explanation:
The plane L can be given another name using uppercase letters only. The plane will require three letters name so that it represents a complete angle. The names can be assigned using the point to point method or randomly. There are two choices available to name the current plane. Plane MNO and Plane PST are the names that can be given to plane L.
