In a sine curve, like a water wave, the high points are the crests and the low points are the (blank)

this is poiselle's equation from fluid mechanic in physics. mech eng

+15-35=-20

going in opposite directions

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.
