The specific heat of liquid water is 4.184 j/g-k. the latent heat of melting (ice to liquid is 6.0102 kj/mol. define q100-0= the amount of heat released by water when it is cooled from boiling to freezing. define freeze = the amount of heat released during the freezing of water. estimate q ratio ? q100-0/qfreeze

Two polarizers are oriented at 70∘∘ to one another. unpolarized light falls on them. what fraction of the light intensity is transmitted?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
