I have a square room that is empty it measures 10 x 10. The height of the room is 10ft. I have an A/C unit that will cool 50 cubic feet in 8 minutes. How long will it take to cool all the air in the room. I am asking this because I suck at mathematics.

I cannot eat beef because we Hindus respect the cows because she provides us milk from childhood much like milk from our moms. That is why I cannot eat beef. Now does buffalo qualify as beef or cow family?

Last night I heard this horrible sound outside, I think it was an animal being attacked. Obviously it was not a monkey but it sounded like one when it was screaming. I could not see the animal but am curious on what it may have been. It ran away when I turned on the light outside. Anyone know of any wild animals that sound like monkey's?

I live near Chicago and it's been stormy all day and all through last night. Today when it was actually calm, it got cloudy and I automatically knew that there was something weird going on and then the tornado sirens went off and afterwards I still saw the funnel cloud.
So, how do I know that something similar is happening at night time, without looking online or turning on the weather channel?

Just in case it does happen.

Yes, we see colour because of surfaces absorbing and reflecting certain wavelengths of light.
What determines the specific colour a particular material, molecule, what have you, would reflect?

p.s. If you know, does it have anything to do with the Hamiltonian eigenvalue problem?

A speedboat begins at the rest and accelerates at +2.01 m/s2 for 6.55 s. At the end of this time, the boat continues for an additional 5.80 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at -1.49 m/s2 for 8.80 s.
(a) What is the velocity of the boat at t = 21.15 s?

(b) Find the total displacement of the boat.

Thank you so much!!!!!!!!!!!!!!!!!!

as long as you kinda show some work, you don't need to explain.

I have been looking into the history of genetic modification. I located a source that stated that the 1st fertile interspecific hybrid was created in the 1700s and moreso, that the 1st fertile intergeneric cross was created in the 1920s. I found that the first artifical interspecific hybrid was created by Thomas Fairchild in 1719 (carnation x sweet williams), but I can't find any info on whether it was fertile. I noticed also that the first cereal hybrid was bred between wheat and rye - triticale - in 1876 by Wilson. As well, I noticed that the first case of hybrid vigor was observed in tobacco by Joseph K lreuter in the 1760s. I was guessing orchids, but their first interspecific cross was done in the early 1900s. I also came across mention of an interspecific cross in Darwin's Origin of Species, where W. Herbert crossed Crinum capense with C. revolutum to produce fertile hybrids, but this must have been in the 1850s. As to the 1st fertile intergeneric hybrid, I have no leads.
