Thanks for your reply and tidying up my equation! 4λr should equal 0.0093 mm. I tried plugging it in as follows and still get the same answer.. 0.0093 mm = 4(0.0005893mm)r r= 3.95 mm These measurements were obtained using a Vernier scale, thus they are to three decimal places. The final...

Homework Statement These are problems from a Newton rings experiment where a lens was placed on a flat surface and the interference patterns created Newton rings. I measured the diameter of the first five rings and then plotted a graph of d^2 against N (number of the individual ring). These...

I did Pythragoras to find the missing vector. (8000)^2 + (6000)^2 = c^2 c=100 m/s tan\theta = 6000/8000 \theta = 37 I got 100 m/s for my velocity and 37 degrees N of W. Is this right?

This is what I have so far. Am I on the right track? Will the resultant be the hypotenuse? http://img408.imageshack.us/my.php?image=physicsay5.jpg

Homework Statement a 600 kg canon, initially at rest, exploded upon firing and broke into three fragments. One fragment of mass of 200 kg traveled east at 40m/s and a second fragment of mass 300 kg traveled due south at 20 m/s. What was the velocity of the third fragment? Homework...

It can be any time where you uncover something new about yourself as an individual. It's an on going process throughout life - not just at infancy.

Can anyone please help me out? I've been stuck on this question for over half an hour. :(

What impact(s) has self discovery had on you? Were the effects adverse or otherwise?

Homework Statement A 3000kg space capsule is traveling with a velocity of 200m/s. In an effort to alter its course, it fires a 25.0 kg projecticle perpendicular to its original direction of motion at a speed of 2000 m/s. What is the speed of the capsule and by what angle has its direction...

I'll try that - thanks!

Here's what I have done u = x^2 v = 3x^2 e^(x^3) du = 2x dx dv = e^(x^3)2x dx I = x^2 3x^2 e^(x^3) - integral of 3x^2 e^(x^3) I'm not sure how to integrate the 3x^2 e^(x^3).

That's how it is in my textbook though.

I'm not sure how to use the tags here so I'll just post a picture. http://img231.imageshack.us/img231/1954/52551832cl9.png

Sorry about that. I'll try again.

Homework Statement Integrate x^2 e^x^3 dx Homework Equations I = uv - integral of u'v The Attempt at a Solution I don't know where to begin this question at all and have been stuck on it for the past half hour. Any help would be really appreciated. :(
