Science & Mathematics - 25 October 2006

I am in a very competitive class in med-school and we have a 'pseudo' exam (a tough CA) coming up next week. Note, I am yet to start preparing for it.

It just doesn't make any sense to me. It helps people who are in desperate need of help what are we going to do? Throw away the stem cells and tell people "sorry we'd like to help you but they won't let us so you're going to die"?

So, they mapped all the genes in humans. What do you think will come of it? How long do you think it will take?

One day, Jackie was having a really hard time thinking of a cute outfit to wear. She kept coming across the same thought, "if you have 4 pairs of jeans, 3 shirts, and 2 pairs of running shoes, how many different outfits can you make?" Each outfit contains one pair of running shoes bought from the FootLocker.

I made a scan of the problems

I'm supposed to show the logical proof for each of these, but I don't know how to start!!!

If you could do just one of these, I WILL BE VERY GRATEFUL.

Thanks!

See http://news.bbc.co.uk/1/hi/sci/tech/1883348.stm

It was a collosal failure Their N1 rocket had 30 engines The American Saturn V produced the same power with only 5 engines.

The need for all those engines was the Russians undoing as there was no way they could balance the power output with all those engines firing.

There was a catastrophic explosion that destroyed the whole of the launch complex, and that was the end of the Russian effort to put a man on the moon.

All those who disbelieve the American effort, for whatever ridiculous reason, go read the history.

Since Apollo was scrapped nobody has been beyond Earth’s orbit. It requires an extra large booster to get that final drive to achieve escape velocity. To get that power, the thing needs to carry thousands of tonnes of extra fuel.

The only rocket big enough to achieve this was the Saturn V, which was scrapped. That is why we have not been back to the moon.

A sprinter who weighs 670 N runs the first 7.0 m of a race in 1.6 s, starting from rest and accelerating uniformly. What are the sprinter’s (a) speed and (b) kinetic energy at the end of the 1.6 s? (c) What average power does the sprinter generate during the 1.6 s interval?

I recently asked a question asking "how old was Isaac Newton when he discovered calculus" and people tried to correct me and said that he invented it.

I believe that math is discovered, not invented. Pythagorean Theorm was not some idea invented to say that a^2 + b^2 = c^2, but was a recognition that, if given a right-triangle, this is how all sides behave.
All mathematical formulas are used to explain events that happen in nature. These events were always happening, and it just took someone to come along and discover how it was happening. Thats why i think math is discovered. What do you think?

What do you think?

At a distance of 45ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 49ft/sec when it is at an altitude of 112 ft, how fast is the distance between the helicopter and the man changing at that instant?
