Read the excerpt from A Black Hole is NOT a Hole.
According to context clues, which is the best definition of
event horizon?
Remember that super-pulling space around a black hole
the one with the strongest pull in the universe? That super
pull is the close-up gravitational power of a black hole. Here
in this zone, the gravity is so intense that nothing can move
fast enough to fly, launch, jump, or zoom away.
Around this extreme zone is a boundary called the event
horizon. This boundary acts like a point of no return. Once
past it, there's no going back. Only black holes have such
extreme gravity zones, and only black holes have event
horizons. This is what makes a black hole different from
everything else.
an area with not many events occurring near the horizon
an area with many events occurring near the horizon
a border surrounding very weak gravity found around a
black hole
a border surrounding the zone of strong gravity near a
black hole

Suppose an economist believes that the price level in the economy is directly related to the money supply, or the amount of money circulating in the economy. the economist proposes the following relationship: p=a x m - p=price level - m=money supply - a=a composite of other factors, including real gdp, that change very slowly over time. how might an economist gather empirical data to test the proposed relationship between money and the price level? an economist would persuade the federal reserve to change the money supply to various levels, and observe the resulting changes in the price level. unlike researchers in the hard sciences, economists cannot study complex relationships using data. economists do not usually develop theoretical models of the economy but only analyze summary statistics about the current state of the economy. an economist would look for data on past changes in the money supply, and note the resulting changes in the price level

Witch is an example of a non durable good?

The green fiddle has declared a $5 per share dividend. suppose capital gains are not taxed, but dividends are taxed at 15 percent. new irs regulations require that taxes be withheld at the time the dividend is paid. green fiddle stock sells for $71.50 per share, and the stock is about to go ex-dividend. what will the ex-dividend price be?
