La figura consiste de dos masas m1 y m2. Si el sistema se mueve libremente y la tensión de la cuerda es 40N y m2= 9kg. Calcular el l valor de la masa m1. Usar g= 9,8m/seg2 Esto es de leyes de Newton

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.​
