I guess I got so used to the fact that dogs are colorblind, I started thinking EVERY animal is colorblind. I'm hoping that isn't true. Specifically I was wondering if Sugar Gliders could see color or not.

Would this give conspiracy theorists the fuel they need to convince the public that the first moon landings newer took place.

Factor the polynomial completely. If the polynomial cannot be factored, write prime.
24k3m - 81m4

(6km - 9m2)(4k2 + 9m2)
3m(2k - 3m)(4k2 + 6km + 9m2)
3m(8k - 3m)(k2 + 6km + 9m2)
3m(2k + 3m2)(4k2 - 6km + 9km2)

I know that one Telsa is 10,000 Gauss but I want to know how that cant be interpreted into lbf between two metals...i.e.

if two bars of iron have 1 Telsa of magnetic force between them then how much lbf does that feel like.....with varying distances. between 1-5cm

Hi all, this probably sounds mad, but when I am working out the sum of n terms in a geometric series, when the common ratio is negative I am getting the answers wrong every time and cannot see where i am going wrong.

The book I have has proven the formula

Sn = [a(1-r^n)]/[1-r]

where Sn = sum of n terms
a = first term and r = common ratio

Now take the question when the first term = 5 and common ratio = -2 find the sum of 10 terms

s I put in

{S10} = 5(1 - (-2^10)) / 1 - - 2
= 5(1 - (-1024) / 3
= 5(1025) / 3
= 5125/3

Now the answer is wrong, because it should be -5115/3 which would then give the correct answer to me. The only place I can see how they get this is to have 5(1 - 1024) but I cannot see how this can be....please help its driving me mad!!!!

I've invented a simple way of converting with no tools, any upright vacuum cleaner that takes bags (working on bagless design) to a dust-free, bag-free, and FILTER-free! system.
Without giving up the ghost, it has one thing that needs to be done at each use which requires a simple 'less than a minute' procedure. This is it's only negative, but in my observation it is actually a positive because it 'makes the vac owner take care of the vac. As opposed to neglecting it. After all it is the neglect that ultimately ruines a vacuum cleaner.

If you say ..as the speed of an object reaches the speed of light.... its mass increases infinitely... I will say ...we have been told that the mass of an object is constant wherever you take it? so what is the problem here? why sudden increase in mass...infinitely? doesnt this ideas contradict...or enlighten me with something...because I am curious.

As far as I know, when the light is too intense, the eye pupil contracts to reduce the ammount of light that enters the eye.

So, when this happens, does the eye iris become WIDER?
