Can You Explain This To Me About Blacks

Explain to me about Sihr (Black Magic)?

[2:102] They pursued what the devils taught concerning Solomon's kingdom. Solomon, however, was not a disbeliever, but the devils were disbelievers. They taught the people sorcery, and that which was sent down through the two angels of Babel, Haroot and Maroot. These two did not divulge such knowledge without pointing out: "This is a test. You shall not abuse such knowledge." But the people used it in such evil schemes as the breaking up of marriages. They can never harm anyone against the will of GOD. They thus learn what hurts them, not what benefits them, and they know full well that whoever practices witchcraft will have no share in the Hereafter. Miserable indeed is what they sell their souls for, if they only knew.

Can You Explain To Me What The BLACK HAWK WAR Was?

Black Hawk War 1832

May 1832 - Sac and Fox Native Americans led by Black Hawk left the Iowa territory to return to their homes across the Mississippi in northern Illinois; they had lost their land here under a disputed 1804 treaty.
The Illinois governor called up the militia in response.

July 1832 - Brigadier Henry Atkinson sent 400 regulars and 900 militia to pursue Black Hawk, the chase covering northern Illinois and southwest Wisconsin.

21 July - Battle of Wisconsin Heights.750 militia cornered 80 of Black Hawk's warriors, killing the majority of them.

1-2 August - Battle of the Bad Axe - continuing the pursuit, the US forces concerned Black Hawk at Bad Axe. About 500 Native Americans (which included women and children) were easily defeated by the 1300 Americans, who killed 175 of their enemy (including some women and children) for the loss of only 5 of their own number.

27 August - Black Hawk (who fled Bad Axe after the first day) surrenders.

Can you explain simply what is a 'black body'?

Black bodies are objects that absorb and and emit all electromagnetic radiation. The black body heats up when exposed to electromagnetic radiation and as it heats up it emits radiation.

As the black body becomes hotter, the wavelength of light that it gives off the most of become higher in frequency and increases in intensity. You can see this as a black body radiation curve.

This is why cooler stars and maybe heaters and stoves you see as red, as you heat something more the colour becomes whiter and whiter and eventually blue and then beyond what we can see, into ultra violet and so on.

The thing with black body radiation was, it couldn't be explained by classical physics. To fix this up, this german dude named max planck hypothesised that light comes in packets which have discrete amounts of energy (multiples of a number we know as Planck's constant). With this hypothesis of his, he was able to predict black body curves that have a higher frequency and get correct results!

By suggesting that light comes in packets, he sort of said photons exist, these photons are particles of light. The more photons there are, the higher the light intensity is and the higher the frequency of light is, the more energy these photons have.

Now to relate this to the photoelectric effect. The photoelectric effect is the phenomena where light (and other electromagnetic radiation) can knock electrons off a metal surface.

The problem with this photoelectric effect was that classical physics couldn't explain it either! there was a minimum frequency of light required to knock electrons off an atom and no matter what the intensity of light was shone on it, if the frequency wasn't high enough the electrons wouldn't get knocked off.

To explain this, einstein used Planck's hypothesis which took light as packets.
Einstein said that a minimum energy was required by a photon to knock electrons off. He also said the intensity of light can only affect the number of electrons that are emitted as there are more photons to cause the photoelectric emission.

I hope i have explained this properly, if you have any questions just message me.
Maybe visit these websites for more info:

Also, I highly recommend reading the first few sections on the link that maussy sent, its very intresting!

Can someone please explain the end of "Meet Joe Black" to me?

Ahh yea the best part of the movie.Joe sits atop the stairway (and we are unsure if to heaven or hell) waiting for William. He shed tears as he gazes at the liveliness of the firework. William Parrish walks to him, accepting his fate—and Joe (Death personified) dries his tears and realizes his role as well in this universe. He cannot stay, and neither can William—even though they both admit “it’s hard to let go.”Joe Black takes William over a symbolic stairway/bridge. On the “life” side is where the party’s at, and the other “darker” side is the afterlife. Joe had fallen in love with Susan and towards the end, he realized that Susan is actually in love with the guy she met. Death promised her that she’ll always have the young man in the coffee shop. After taking William with him over the bridge, Death returned Joe—alive.Presumably, they’ll probably find William’s body on the other side of the bridge. They are not walking through a portal of some sort. The bridge part was creative storytelling.

Could someone explain the ending of "Joe Black" to me?

Death (Brad Pitt) gives the man Susan met in the coffee shop his body back.(which death had rather roughly taken when the guy was hit by a car in the beginning of the movie)...so she has this guy back that she had such an amazing coversation with, and Death leaves with her father.
