HELP PLEASE!*******Physics project for kids!!*********?

We Answered:

you can try to make the contraption that shoots a ball out horizantally and drops one vertically at the same time from a certain height, but both hit the ground at the same time because gravity is always pushing down on objects all objects with the same force whether they are moving or not

How to fight a bogus personal injury suit?

We Answered:

I would take the advice of the school's lawyers, and let them represent you, because a) the school is the entity that will end up getting all the liability, if there is any; and b) they're the ones with the money. You'll more than likely get dropped as a defendant, if this case actually makes it anywhere (because it seems pretty bogus to me, based on the info here).

There is a lot of precedent in similar cases that if there IS any fault, it's the fault of the school and not of other students. I don't think you really have anything to worry about, this kid probably just attached the names of everyone who was in the room at the time to his lawsuit. I would let the school and its lawyers handle it and let them represent you in this -- they are used to handling cases like this and are much better equipped.

My Physics Lab?

We Answered:

Well the problem is the experimental setup!

Here it goes......
You'll will need a box/container wuth ahole at the bottom big enough to accomodate the wires, to keep the incandescent bulb.

Keep the bulb in the lower portion. Divide the box into 2 compartment by a metal plate (it would be excellent if its copper)

Fix the plate touching the bulb from above and seal it so that water poured from above wont leak.

Also seal the bottomside of the box by cotton, felt etc.

The box acts as an insulated chamber.
Take a measured quantity of water at room temperature and pour it in the top chamber.

Put the bulb on. Wait for some time to let the system reach a steady state, keeping the voltage constant.

Since you know the initial temperature, quantity of water , you'll find the temperature of the water now and calculate the heat gaind by water (Q) as:
Q = m*s*dT
m=mass
s = specific heat capacity of water
dT = temperature change.

Keep on varying voltage, and calculate Q every time.

You will get the answers required!
