I am doing a science project one how much a persons pules goes up after.......?

It depends on the conditioning of the individual. I did a similiar experiment with a class of 7th grade students, about 140 of them.  The marched in place for three minutes to burn up energy reserves and then continued for two more minutes.  Pulses and respiration were recorded at rest and each minute and for 5 minutes afterwards.  Results were interesting and revealing as to the physical condition of each student.

Up or away from the center of gravity.

Check the Michaelis-Menten equation.It's too long to write it all down for you ;)

almost exactly, assuming someone on earth is doing the measurement. someone moving very fast would get a different result.

The experiment which you have suggested (although incompletely) is a classic method of verifying Bernoulli's equation, and it consists of hanging two balls in the air by strings, reasonably close to each other and blowing air through the gap between them. \n\nSound as the logic behind the experiment may be, it is in fact quite simple to perform the experiment incorrectly. One way in which this can be done is by blowing directly at the balls, which has the undesirable effect of pushing them in a haphazard direction. Hence, while blowing, keep in mind that you do not let your blows land on the surfaces of the balls. The air should strictly pass through the gap. \n \nThe other reason could be heavy balls. \n\nYou are best off using pingpong balls, with their surfaces spaced about 5-7 centimeters ( 2-3 inches) apart.

This would be an awesome inexpensive experiment. as I believe that it does with respect to the diameter of the bubble gravity attraction should be increased with respect to surface area, however this experiment should be conducted in an environment free from draft and circulating air flow.

I dont think its that high, I think its probably less than 50. You probably wont find a very accurate figure out there for something like that.

air resistance.\n\n Do the experiment yourself- if at school- get a teacher to make up a sealed tube, suck out the air (less difficult than it sounds- i remember doing something like this) and then invert it. its very strange.

I agree with the first answer:  Here is something that might help you with maths:  When you have a problem such as this make a 'rough estimate' of the answer.  In your problem almost all the tomatoes were water, nearly 100kg, the water was reduced by 1% - that's very little, it being 1/100 th. So you nearly have the same weight as you started with.  It cannot be 50kg as that would have meant that half the water 50% would have evaporated.  I hope you follow. Go back to my first point, the rough estimate should have been 'nearly 100kg but a little less'.  I hope I have made sense and that this gives you a good idea as to how you should proceed in the future.  Always work out a 'nearly right' answer first.....

100-500 depending on how close you are to the person

Read Newton's 3rd law of motion.\nAlso, use F=ma to figure out your acceleration.

ummmm, maybe increase by a factor of 5 or so. Its an exothermic reaction to begin with and you're not limited by the amount of water( i think, if not not all your drano will dissolve) so it should be about five times the energy released compared to just two grams.
