A1.80m long uniform bar that weighs 608 n is suspended in a horizontal position by two vertical wires that are attached to the ceiling. one wire is aluminum and the other is copper. the aluminum wire is attached to the left-hand end of the bar, and the copper wire is attached 0.400m to the left of the right-hand end. each wire has length 0.600m and a circular cross section with radius 0.250mm.

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.​
