Physics
A dog, with a mass of 8.0 kg, is standing on a flatboat so that he is 26.8 m from the shore. He walks 8.6 m on the boat toward the shore and then stops. The boat has a mass of 36.0 kg. Assuming there is no friction between the boat and the water, how far is the dog from the sh...

Three identical uniform meter sticks are placed on the floor. The first stick lies along the y axis from y = 0.470 m to y = 1.47 m. The second stick lies along the x axis from x = 0.320 m to x = 1.32 m. The third stick is positioned so that one end is on the x axis at x = 0.69...

Physics
If the scuba diver is looking from the water n=1.33 and the other man is above water so n=1, use the equation n1sin(theta)=n2sin(theta). 1.33sin(20)=1sin(theta) 27.06 degrees is the answer, but since it says from the horizontal do 90-27.06

Science
PLEASE HELP ME!!!!! Which requires more energy? Heating up a 350 mL cup of coffee from 25C to 65C? or Warming the surface of a Lake (2,000,000,000 mL) from 28C to 29C. and Prove your answer.
