Four masses a, b, c and d are attached to a shaft and revolve in the same plane. the masses are 12kg, 10 kg, 18 kg and 15 kg respectively and their radii of rotations are 40 mm, 50 mm, 60 mm and 30 mm. the angular position of the masses b, c and d are 60°, 135° and 270° from the mass a. find the magnitude and position of the balancing mass at a radius of 100 mm.

the results is a decrease in air temperature with an increase of altitude.

explanation:

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
