I've always been told that white, or light colors absorb less heat than black, or dark colors. Yet no one has told me why. Thus leading to my question, WHY?!!?

I have Japanese Hornets in my back yard and I live in Ohio, I know they are the Japanese Hornets because I looked on here and it looks exactly the same, 2 inches long and I remember seeing them a long time ago about two years ago but no where near where i lived this is the first time i've seen them where i live, usually they come out at night but i have seen them during the day, two of them got into the house which we did kill them but theres some still on the back porch where i'm guessing is close to the nest, does any one have any suggestions on what to do? these hornets are deadly there stinger contains eyzama or something like that which can dissolve human skin, if stung u have to recieve immediate medical treatment whether alergic or not

If Bob lived on planet earth and suddenly this universe was split into 1000 universes, each exactly identical at the first moment, then when we observe (supposing we can) all 1000 Bobs how similar will they all act? Will they act identical? Somewhat identical? Not at all identical? The main idea is, if there are some events that are truly random (which seems to be very true so far), then how much of an effect will it have on our Bobs. The main idea is are the parameters of possibilities on the macro scale so strict that we could not observe a difference, or are they loose enough eventually discourse after discourse will lead to our Bobs living quite different lives (IE: Eating ice cream instead of donuts 27 years after the universes split while watching TV).

each student is to pick a topic related to either cellular bio, molecular bio, or physiology. I picked muscle physiology..but is there a certain topic about that is easy to research. I would do muscle physiology as a whole..but i think that would be too broad because each thing would have only a limited amount of informaton. So is there a certain topic for muscle physiology?

I work at a nursing home and come in contact with few (not many, but there are once every while) people with HIV. When I do I come in contact with their blood (when they have bloody nose, or get cuts) and I am worried about becoming infected. I do wear gloves but I can't guarantee 100% that it doesn't smudge on my arm or hand. Is it possible to get HIV by touching someone's blood?

I was told that there is one day during the moon's cycle where the face of the moon appears upside down....The southern highlands are at the top of the moon...Is this true? and if it is...why? Or am I misunderstanding....

Half a bee, philosophically, must ipso facto half not be. But half a bee, has got to be, vis a vis its entity. Do you see? But can a bee be said to be or not to be an entire bee, Due to some ancient injury?

A ball is shot from the ground into the air. At a height of 9.1m, its velocity is (7.6i+6.1j)m/s. (i horizontal and j upward)
a) to what max. height does the ball rise?
b) what horizontal distance does the ball travel
(X-Xo=(Vo.COSangle)t right?)
c) what are the magitude and d) angle (below the horizontal) of the ball's velocity just before it hits the ground?


I did figure some parts out; since i is horiz. and j is upward the ball is still climbing. The magnitude of v is sq root of (7.6^2)+(6.1^2)=9.75 m/s and the angle at that moment is arctan(6.1/7.6) = 38.75degr.

I thought by calculating the horizontal range R I would get somewhere but I'm stuck again.
I think with the instantaneous velocity after 9.1m I must be able to calculate the t and the Vo and go from there but how?
Who can help me?
