A tube driven by a speaker displays resonances at 450 Hz and 600 Hz with no resonances in between. The fundamental frequency was found to be 150 Hz. What are the boundary conditions on the tube

i wanna say it’s between b and d, leaning more towards b.

part 1: which substance has a higher solubility?

a

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

pythagoras' theorem

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

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
