except they multiply not add

q is heat gained or lost; this is the equation they used in the solution so its got to be right...

Homework Statement A 42kg block of ice at 0°C is sliding on a horizontal surface. the initial speed of the ice is 7.3 m/s and the final speed is 3.5m/s. Assume that the part of the block that melts has a very small mass and that all the heat generated by kinetic friction goes into the block...

well look at that... it worked haha thanks guys :D

p1/ρg=h ? some one give me a solution for gods sake :p

its asking how high the faucet should be so that no water would reach it from the pressure gauge at the bottom of the house that much i understand. but I am still not getting how i would solve for that. i got the pressure of water coming out of the faucet at 6.5 but i don't see how that number...

gh=p1+pgh?

The main water enters a house on the first floor. the line has a gauge pressure of 1.9x10^5Pa a) A faucet on the second floor 6.50 meters above the first floor is turned off. what is the gauge pressure of this faucet? b)how high could a faucet be before no water would flow from it even if the...
