An object with a mass of 30 KS (300N) is suspended from the two ropes. Each rope makes an angle of 30 degrees from the vertical. The angle between each rope is 60 degrees. What is the
tension in each rope? Scale 10cm=300N (F.:=mg g=10m/s)
60°

he kicked it 10 feet straight up into the air? i think this works.

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
