Physics - November 2006

1. Before Galileo's time, what forces were people aware of? and during Galileo's time what forces did he discover relating to physics?


2. What physical quantity is a measure of the amount of inertia an object has?


3. You are having trouble starting your car. A friend offers to give you a push. A second friend comes along and also offers to help. How does the acceleration change when two people push compared to when only one person pushes?

also another Q:
a ball started from rest and rolled down a steep driveway. At the end of 4 seconds the speed was 12m/s. What was the acceleration?

Like how they function and how they are made and stuff.
ELF refers to Extr. low frequencyAnd i dont care about the medium. If there is a significant difference you could note them.
Thanks

There was a similar question and here is a part of one answer..but it doesn't make any sense to me...

"..external force which existed during the formation of earth. This force on earth imparted earth a velocity that was greater then critical velocity to revolve in a circular path around sun but less than the escape velocity. Any body imparted with such velocity will rotate in an elliptical orbit.."

I can't make sense out of this explanation, but is it similar to the following statement....This is what I have read from other sources..: If the balance between large body's gravitational pull and centrifugal force is not perfect, the orbit will be elliptical, but to me it would mean that either the Moon will fall into the Earth or it will leave Earth's orbit, depending which force will be stronger...I really don't understand!!! Is there a purely logical explanation without complicated mathematical formulas???

In an electrical circuit, there is a 12v battery and two resistors in parallel. One is 14 ohms, the other is 10 ohms. What is the potential difference across the 14 ohm resistor and why? Use small words when explaining!

Thanks

Ive figured out a way to look into the past... If you could make a camera travel faster then the speed of light... then take a picture... it would give you a picture of whatever happened X amount of time ago that you traveled faster then the speed of light...

RIGHT?

and! If you could reverse this process you would be able to look into the future right? But i think that is impossible...

A cyliderical metal shell with the inner radii of 0.200m and 0.300m, respectively, carries a net charge of 4.0 x 10 pow -8 C/m.Along its center there is a wire with a uniform charge of -12.0 x 10 pow -8 C/m. ( This System is smilar to an electrostatic air cleaner). (a) Find the Electric Potential caused by this system of electric charges, using the outer surface of shell as reference point for the potential. (b) An electron is formed by ionizing a gas molecule 0.00100 m from the wire. with what kinetic energy in (electron Volts) and with what speed will the electron hit the metal shell, assuming it does not suffer any collisions enroute.

All this talk of do you believe in other dimensions is silly, where do you think all the socks go, their shape is the most conjusive shape to interdimensional travel and so they travel a whole lot, not merely staying in another dimension but moving through lots in their lifetime, which is infinite.

I wonder if a sockwas big enough could it become pan dimensional like the mice in Hitch Hiker, ie if it filled one or more dimensions up could it live in more than one. If so maybe we already live in several dimensions, maybe every atom in our body is a seperate dimension and live entirely acording to its own path, and all our atoms are changing dimensions every moment, oops me legs gone again, no there it is, ho ho
