I am planning on studying in the US. It appears that the nuclear industry in the US is in fact not good at the moment. Btw I am fluent in spanish and english.

Hi, I am currently trying to decide between a master in nuclear or mechanical engineering. I did my BS in mechanical engineering. If I dicide in a MS in nuclear engineering I am planning in focusing in the development of better and safer fission reactors and later on doing a PhD in fussion. I...

bcrowell: You are right! What i meant to say is that time goes slower in a "strong" gravity field and faster in a weaker one. The argument that I don't understand is why does this effect happen? I am reading the links, let's see if they help.

Im having trouble understanding the gravitational dilation of time concept. I know its states that time go slower on higher gravitational potentials and i know it has to do with light loosing energy (decrease in frequency) as stated in Stephen Hawking's Book "A brief History of Time". How does...

Hi, I am currently an mechanical engineering student. When i finish my BS in engineering i want to a BS in physics. Will i have to take a lot of additional courses in the physics BS?

but isn't cosine adjacent/Hypotenuse?

Im having trouble understating this: The last part: DEz=8333N(5/15) where does this come from? 15m is the hight and 5m is the base of the triangle.

thank you very much :)

Im doing a balloon problem. The problem states that the volume increases linearly with pressure in the solution manual they that P2/P1=V2/V1 i think that is related linearly but i can't figure how. Can some explain?

Just to be sure @ rcgldr we are talking about forward speed (velocity that the airplane is going to be traveling without any load and discarding the weight of the plane)?

Im trying to get the Hp or W for the O.S 61FX RC airplane motor that has a propeller size 13x6 that give 10400rpm. The reason for this is to know the max speed that it can obtain discarding the weight and everything.

You can go and read about The laws of universal gravitation, bernoulli's principle, laws of thermodynamic, Coulomb's law, Ohms law. You can start.

Can someone explain it please?

If they go in the same direction the add up. 5Tesla up + 10 Tesla up = 15 Tesla. 10 Tesla up + 5 Tesla down= 5 Tesla. Its all vectors.

The pressure in a pressurized water tank is measured by a multi-fluid manometer. The gage pressure of air in the tank is to be determined. Assumptions: The air pressure in the tank is uniform (i.e., its variation with elevation is negligible due to its low density), and thus we can determine...
