A 350 N uniform 1.50 m bar is suspended horizontally by two vertical cables at each end. Cable A can support a max tension of 500 N without breaking and cable B can support 400 N. You want to place a small weight on this bar. What is the heaviest weight you can put on without breaking either cable?
A) 450 N
B) 500 N
C) 550 N
D) 300 N
E) 350 N
Where should you put this weight from the left end of the bar?
A) 0.40 m
B) 0.61 m
C) 0.75 m
D) 0.84 m
E) 1.0 m

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.​

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

wavelength divides in half and speed stays the same.
