thanks for the reply. i will take another shot at working the problems when i get back from school. the TA thing is an honest to god true story. my partner went complain to the dean or department head. the guy in charge of the TA is the old department head who is the most pompous a hole you have...

i have to say physics kicks my butt. i never worked so hard in my life to earn a D in a class. now, i have to take the lab for that course and they are trying to kill us! the TA tore up my lab partners work because he didn't like the way she presented it in her lab book! ok, so that is what i am...

alright! you learn something new every day!:biggrin:

thanks for sticking it out with me. my textbook sucks. it had the two discussed side by side and never differentiated between the two. i just read another article where it explained this. it seems obvious now. final try: (a) would take a longer time to boil away (b) the cooling system...

(a) sorry, i misquoted the reference. it said "if latent heat of vaporization" cut to a 10th of its original value. not "boiling point". here is the full quote, "If the latent heat of vaporization Lv of H2O were one tenth of its actual value. Other things being equal, if the stove is supplying...

Borek, LOL i know you are trying to pull me through the tunnel but i am having a hard time fitting. (a) the higher you put a stove the faster the water boils and the more rapidly the water evaporates out. if you boil two pots of water at the same speed and one has twice the boiling point...

(a) water boils because it is experiencing rapid evaporation and turning to a gas state. the bubbles are the gas escaping. i realize that it would take twice the energy to boil the water but what does that have to do with the rate at which it evaporates? i am beginning to lean towards it...

Suppose the latent heat of vaporization of H2O were twice its actual value. (a) Other things being equal, would it take the same time, a shorter time, or a longer time for a pot of water on a stove to boil away? (b) Would the evaporative cooling mechanism of the human body be as...

thank you Hoot. i just wanted to make absolutely sure because this question is for some extra credit that i desperately need.

Question: Is more elastic potential energy stored in a spring when the spring is compressed by one centimeter than when it is stretched by the same amount? my conclusion: part of the definition in the book states that Elastic Potential Energy is the energy that a spring has by virtue...

thank you my friend.

A 88.0 kg person stands on a scale in an elevator. What is the apparent weight in each of the following situations? (a) when the elevator is accelerating upward with an acceleration of 1.40 m/s2 (b) when the elevator is moving upward at a constant speed (c) when the elevator is...

thanks doc

thanks for the quick reply. i am taking this class for the third time and i am finally reaching out for help. so sense the ship is traveling west i set the opposing forces as negative: net F = 3300N - 490N - 1200N = 1160N then F= ma so a= F/m = 1160/6800 = 0.171 m/s squared due...

In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 42 m/s (around 90 mi/h) in a time of 8.1 s. The mass of the car and riders is 4800 kg. Find the average net force exerted on the car and riders by the magnets. my...
