1. The problem statement, all variables and given/known data (k^(1/5))/k^4/5 * k^-1 2. Relevant equations 3. The attempt at a solution step 1(k^(1/5))/k^4/5 * k^-1 step 2: (k^1/5)/(k^4/5) * (k^5/5...
Kirchhoff's Law 27 Aug 2013 | 05:51 am
When you start going around a loop to try and determine whether to add or subtract each voltage in that loop, how do you decide which? For example see the diagram just above Q7. http://www.facstaff.b...
Can you Convert these units? 27 Aug 2013 | 05:50 am
Dear reader, I thought I was getting the hang of converting units but came across a thermal conductivity value and the unit was given in: [BTU/hr-ft-R] :eek: I assume the 'R' means 'Rankine'. I wan...
Best algorithm for an object that moves across an area 27 Aug 2013 | 05:48 am
Imagine a rectangular plane with dimensions X and Y. On that plane is a car. The car is about Z meters wide (the front bumper width, or up-down width in the image below). The car travels at a velocity...

Another trig expression 27 Aug 2013 | 05:01 am
1. The problem statement, all variables and given/known data Simplify: (sin t + cos t)2 / sin t cos t 2. Relevant equations tan t = sin t/cos t cot t = cos t/sin t cot t = 1/tan t 3. The atte...
binomial formula for spherical tensors 27 Aug 2013 | 04:51 am
We know that the Newton binomial formula is valid for numbers in elementary algebra. Is there an equivalent formula for spherical tensors? If so, how is it? To be specific let us suppose that A an...
"gravitational field strength" 27 Aug 2013 | 04:49 am
Hi all, I've been reading some lecture notes by G. t'Hooft, available from http://www.staff.science.uu.nl/~hoof...enrel_2010.pdf On page 12, t'Hooft is discussing the Rindler space of an observer u...
Is Time a Scalar or a Vector 27 Aug 2013 | 04:47 am
In the equation x = vt it is generally accepted that x and v are vectors and that they have a common eigenvector. Each vector is the product of a scalar and a unitary eigenvector. Dividing both sides ...
