Physics - August 2006

Indeed. A black hole is just a collapsed star, compressed to the point that it's gravitational pull is astronomically more powerful that the gravitational pull of a regular star (Keep in mind that a regular star's gravitational pull is strong enough to hold planits in orbit of it for billions if not trillions of years.... AND strong enough to pull comets from the middle of nowhere into it's orbit) which is no small amoung of force.

Why do so many people let others fill their head with drivel. How can anyone even be sure of the existence of black holes? Did they see one from a telescope? Oh, please. I once saw an equasion that illegedly explained how powerful a Black Hole's gravitational pull was. I sure would like to know how they came up with this wonderful theory, since they've never even seen a damned black hole.

Whenever anyone asks me where I think people go if they enter a black hole, I always say, "Well, I guess that all depends on what kind of life they led beforehand!!"

My friends new girl friend said she has a major in physics. She only bartends, and when asked why she doesnt do something with her college degree, she says she makes more money bartending. Ive seen where she bartends, it is not a richy place by any means, its more a gothic bar. I think she is full of ****......whats your opinion??

The boiling point of water is 100*C. Had it been so, the water evaporated from the sea water would also have had the temperature of 100*C during day time (as it continuously evaporates during day time). But I can very easily play and swim in sea water which is not posibble to do at a temperature of 100*C. Explain this phenomena.

I thought that the same amount of energy was needed to move a something no matter how you move it, the energy just gets displaced. Where does it get displaced when you ride a bike?
Sorry, my headphones died on my morning walk so I had time to think about this.

On a hot hot summer day I like to go to local supper market to buy a tub of my favourite ice cream that bring home in shopping bag. It is hot hot outside the bag, and it is frozen cold ice cream inside the bag.

Now, according to the first law of thermodynamics, heat always flows from a reservoir (an object at high temperature) to a sink (a object at low temperature) when both are placed in contact with each other. The mode of heat transfer this way is called conduction of heat energy.

The question is - if heat flows from hot outside the bag – the big giant reservoir at about 35 degrees – to the cold ice cream inside the bag - a sink for heat below zero degree. Then why the bag, in the path of the heat flow, should get cold?

A basketball player is fouled and knocked to the floor during a lay-up attempt. The player is awarded two free throws. The center of the basket is a horizontal distance of 4.21 meters (13.8 ft.) from the foul line and is a height of 3.05 meters (10 ft.) above the floor. On the first free-throw attempt, he shoots the ball at an angle of 35 degrees above the horizontal and with a speed of 4.88 m/s OR (16 ft./s) (initial velocity). The ball is released 1.83 meters (6 ft.) above the floor. This shot misses badly. Ignore air resistance.
a.) What is the maximum height reached by the ball?
b.) At what distance along the floor from the free-throw line does the ball land?
c.) For the second throw, the ball goes through the center of the basket. For this second free-throw, the player again shoots the ball at 35 degrees above the horizontal and releases it 1.83 meters above the floor.
What initial speed does the player give the ball on this second attempt?
