the intiial pressure of a mass of dry gas in a rigid vessel is 4.5*10^5Pa. The volume of the vessel is 0.1m^3. It is connected to a vacuum pump, whih consists of a cylinder fitted with a piston. The pump cylinder has a volume of 0.005m^3. i am supposed to determine the number of strokes...
Homework Statement
A solenoid of cross-sectional area 2*10^-4 m^2 and length 0.5m having 500 turns is to be used to produce a uniform magnetic field some distance close to the center of the solenoid. Find the current that must flow in the solenoid to produce a magnetic flux density of 3*10^-3...
Well, to start with, the university in my country does not offer Aerospace Engineering, that's why I plan to do it as a masters. And no, I'm not 100% sure, i might end up doing nanoelectronics engineering instead. I just wish to know whether a bsc math and physics or a bsc in...
Hi,
As from next year, I will be attending university. At this point in time I am studying Pure Mathematics and Physics at A-level. The way I see it right now is that once I get a degree I wish to do a Masters in Aerospace engineering. My question is, what would be the best degree to get so...
Homework Statement
A curve has equation (x^2 - 2x + 2)/(x^2 + 3x + 9). I need to prove that the range of values of y for this curv eis 2/27 =< y =< 2
I know how it should be worked but I can't understand why it's done that way.
My teacher simply arranged the equation in the form (x^2 +...
I'm currently studying pure maths at advanced level and I can honestly say that I understand everything that the teacher says and I manage to do all the homework he gives us and so on. Given the correct amount of time, I could probably work any problem concerning topics that we have already...
I think I wasn't 100% clear earlier. I am willing to go further than just a bachelors degree. In fact I would love to do a masters, or maybe even more since i love studying. To be completely honest, I love math even more than physics. That's one of the main reasons that i had a bsc in math and...
Hi guys,
Well I'm 17 and in a bit less than a year I'll be doing my A-levels and I'll have to choose what to study at university. I am really in love with math and physics (which are the subjects I am studying @ A-level) but I really don't know what I should choose. On one hand I know I would...
Homework Statement
Two wires each of 2.50m long, one of steel of diameter 1.0mm and the other of copper of diameter 0.56mm are suspended from two points in the same horizontal plane 200mm apart. The lower ends of the wires are fixed to the two ends of a uniform bar 200mm long and of weight...
Homework Statement
I have this problem which is confusing me ALOT! my lecturer isn't very good and I really need to understand this by tomorrow because I got a test.
Let's say there is an object of mass 50kg in an elevator. So, from my knowledge, when this lift is at rest or moving with...
muppet, that sounds very similar to what I had in mind. But after completing your undergrad program, can you enter a mechanical engineering graduate program for example? or?
Maths _OR_ Physics? My university says that the candidate can choose any 2 subjects to major in (from the sciences group) and math and physics are in the same group. so I guess you get a degree in Math and Physics not in one of them.. or maybe I'm mistaken
Hi,
Lately I've been having second thoughts about whether I want to pursue a career in engineering or a career in math and physics and end up doing research. So here are three questions which i'd like being answered :)
1. Let's say I get a B.Sc in Mathematics and Physics, will I then be...
Hi guys. I have just started 6th form, meaning that in 1.5 years I'll be starting university and will have to choose a major. At 6th form, I choose Pure Math and Computing at Advanced Level and I choose Physics at intermediate level. However after a couple of weeks at school I'm realising that I...
