I am currently a Junior at the University of Illinois at Urbana-Champaign and a participant in the dual degree program. In a total of four years, I intend to receive a B.S. in Mechanical Engineering, a degree complemented by a B.A. in Mathematics, and still maintaining Honors status. Ideally, after graduation, I would like to work on an international scale; not simply from a desk in Chicago or New York or wherever in communication with the global population, but abroad--in Hong Kong, Singapore, London, Sao Paulo, etc. I believe the most practical way of be able to do this would be in engineering consulting. Does anyone know of large companies that desire (mechanical) engineers for international work? Or career paths aside from consulting which would provide me with such international opportunity? I'm rather lost with what I want to do, so any advice would be much appreciated. Thank you.

Large cockroaches can attain a speed of 1.70 m/s in short bursts. Suppose you turn on the light in a cheap motel and see one scurrying directly away from you at a constant speed 1.70 m/s as you move toward it at a speed of 0.730 m/s .

If you start a distance 0.990 behind it, what minimum constant acceleration would you need to catch up with it when it has traveled a distance 2.00 , just short of safety under a counter?

Thanks in advance guys :D

The general (nonzero) solution of the homogeneous differential
equation
(x2+y2)dx+2xydy = 0
can be written as f (x;y)+x3 =C
f (x;y) = (Note: the notation for absolute value of a number y is abs(y)

Please explain it as easy as you can and please try using the terms "adhesion" and "gravity".

Need this as soon as possible. Before tomorrow.

Or the latest sunrise fall on a day weeks after the winter solstice? The winter solstice may be the shortest day of the year, but it's not the day of either earliest sunset nor latest sunrise. For the southern hemisphere, the situation is shifted to the summer solstice.

Why not? Rain and snow storms are both precipitation. Why does do you never see thunder and lighting during snow storms?

People say it corrects a chemical imbalance as if depression were an illness. There is a chemical imbalance because you are unhappy not because you have caught some contagious disease. Alot of people tell me I should get medication because I am depressed and never really happy with anything anymore. And I say things like life is just an endless circle of stress and doing the same old **** until you die. Anyone with a brain notices these things though. Why am I somehow crazy for being honest to myself? The real question here is even if it's a chemical imbalance. That is caused by unhappiness correct? Why is it that people view depression as a disease that can be cured through medication?

A glass ornament of mass 575g sitting on a table is subjected to a resonant frequency of 440hz. The ornament breaks into three pieces that travel horizontally across the frictionless tabletop. Fragment A has a mass of 168g and fragment B has a mass of 212g. What is the magnitude of the momentum of the third piece of glass fragment c?

Here's the entire question:
A +5.2 µC charge is placed at the origin and a -2.7 µC charge is placed at x = 25 cm. At what coordinates can a third charge be placed so that it experiences no net force?

Here's the hint my teacher gave us:
The point HAS to be along a line connecting the two charges. But it doesn't have to be BETWEEN them. Do this one like we did the force = zero on a third mass. But instead of x and r-x for distances, you use x and r+x if it is OUTSIDE.

I have been trying to do this problem for ages, but still can't get the right answer. Can someone help please? Thank you for your time.
