Bryce is trying to conduct a chemistry experiment. he needs his water to be exactly  65 ℃. right now in his beaker he has  187.5 g  of water at  15.5 ℃. bryce also has a pot of boiling water which is at  96 ℃.

how many grams of water should he pour from his pot of  boiling water  to get his water to exactly  65 ℃.

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
