I have seen footage of the shockwaves that nuclear bombs produce as i am sure you will have. I often wonder how the footage was shot as everything seems to get practically wiped-out eg. small buildings, trucks

A structural I steal beam has a density of 7.56 x 10^3 kg/m^3.

What is the mass of a section 1.50 m long?

And it shows a figure of an I beam, the top is 15 cm long, the side is 36 cm long, the widths of the 3 parts of the I are 1.cm wide.

so m=pV, I know the density, but how do I figure out the volume?

Somethin to do with Area times height, but I'm not gettin it right....

I got .54m^3 as the volume and that's wrong.....

If it takes 8 minutes for the sunlight to reach earth, then we're seeing the radiance of the sun which was reflected 8 minutes ago, or in short we are seeing the sun how it was 8 minutes ago in the sky. Does that mean that we are seeing and living in the past?

i lately found some good description about how to imagine dimensions .. checkout this

http://www.tenthdimension.com/flash2.php

now it came to my mind.. could momentum be the result of a kind of restriction to move freely in a higher dimension ?

Any input on this welcome..
as usual i think about this question as a testbed to get alternate ideas on things .. hopefully its not too esoteric ;)
thank you

Can science explain 'free will' - or is it just an illusion?
Could it be that everything that's ever happened was decided at the 'big bang'? like one big science experiment full of pre-determined chain reactions?

I want to express x as a function of t given the following:

dx/dt = sqrt(c - [3 k x^2]/4)

Can I integrate it w.r.t. t and if so how? And if not, how do I go about solving it?
