Does it come down eventually? Is it possible that if he stands there long enough the one that fired it could get killed, or does it move with the curving of the Earth etc. I've only done GCSE physics so simple answers needed please!

My question is that during lightning there is a heavy discharge of electric current on the bus and due to electrostatice shielding the bus protects us but due to the heavy discharge of current the bus will get charged heavily, now where would this charges go? How would the charges flow to the earth as RUBBER tyre's are insulators

how do you figure out how much heat you release when you exercise? how long would you need in order to heat up the room?

In conjuction with my last question" A man dropped into a whole that runs through the Earth and out the other side" which i have some excellent answers to. I will choose one soon but i have another poser?? If, like the majority have said that the man who falls through would end up in the centre of the tunnel (centre of the earth), Would he be suspended in animation, floating, or crushed by gravity?

Hi. I'm trying to deconvolve two functions (form: ax^b exp(-x/c) ) with each other. I'm using the discrete fourier method and MATLAB. Sometimes I get a peak, and with other curves I get a peak followed by a small valley. Where does this valley come from? How can I reliably deconvolve these curves? thanks.

If you could drill a whole right through the earth and it's core, from the north pole to the south. The whole would be 100 metres in diameter and would be made of an alloy which did no melt or get react with the magma core. It's a hyperthetical question but:: What would happen if a man jumped onto the whole that went straight through the earth and out the other side. Would gravity eventually stop him at the centre or would he come flying out the other side??????

Q. A cylindrical bar of length ‘L₀’ and diameter ‘d₀’ is deformed using a force ‘F’. It should NEITHER experience a Plastic deformation NOR a reduction of diameter ‘Δd’ more than 7.5x10^(-3)mm. Which of the following material is suitable? Give a solution and reason to justify your answer.

length, L₀ =100 mm
diameter, d₀ = 10mm
change in diameter, Δd = 7.5x10-3 mm
Force, F= 27500 N

Material - Elasticity Modulus -- Yield strength --- Poisson Ratio
alloys - Giga Pascal -- Mega Pascal --- ratio
1. Alumin - 70 -- 200 --- 0.33
2. Brass -101 -- 300 --- 0.35
3. Steel - 207 -- 400 --- 0.27
4. Titanium - 107 -- 650 --- 0.36

How would I get the log (lg) to the other side of this equation?

lg (d/10) = - 0.46

I want d/10 to be on one side, with the log and -0.46 on the other... How can I do this using my calculator?

Any help would be appreciated.

I think I know the basics of the electroscope, but I am still not confident. What is the difference when a negatively charged rod is held close to versus actually touching the metal head of the electrscope? In general, the positive charges would be attracted to the negative rod, while the negative charges on the electroscope would repel, thus making the gold leaf rise, right? And oppositely, if a positively charged rod is placed close to the metal head of an electroscope, then the electrons would be attracted, while the positive charge would make the leaf rise? Is this correct? Any advice would be appreciated... Thanks
