UN FLUIDO DENTRO DE UN RECIPIENTE, EJERCE FUERZAS SOBRE LAS PAREDES DE ESTE, POR LO TANTO SE NECESITAN CONOCER DOS MAGNITUDES QUE SON LA PRESIÓN Y LA DENSIDAD. EXPLICA CADA UNA DE ESTAS MAGNITUDES Y ESCRIBE CÓMO SE EXPRESAN MATEMATICAMENTE.

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.​

c

explanation:

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
