A 10.0 m wire is hung from a high ceiling and held tightly below
by a large mass. Standing waves are created in the wire by air currents
that pass over the wire, setting it in motion. If the speed of the
standing wave is 335 m/s and its frequency is 67 Hz, what is its
wavelength?

b) 10 minutes

girls stopped for 10 minutes.

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
