Cho biết Mặt trăng quay một vòng xung quanh Trái đất mất 27 ngày đêm. Tính vận tốc góc của Mặt trăng.
A. 8,5.106 rad/ s B. 4,2.106 rad/ s C. 2,7.106 rad/ s D. 6,3.106 rad/ s

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
