You can use your leisure for more useful things.

I think..... a=F/m=kx/m

Lightning occurs first. It's an electric spark across a very high potential difference.

You know A5(=A1+A2+A3) and V=12V , so find equivalent resistance. Then find the value of each resistance R.

To learn science you need to learn scientific terms too.

You need to determine R1, R2 and R3 by Ohm's Law. Then find current magnitude in ammeters A4 and A5.

After some thoughts, I get that there will be no jerk or change in acceleration ( which I presumed). Relating the dV/dt=r with the Noyes-Whitney equation, we get a good thing. Now we define terminal velocity and then use it to equation. That reduces it to one unknown, other than the coefficients which are experimentally determined. So we get a single equation with dR as the unknown. Solving for this R by transposition and integration.

thanks for the info imatfaal

Energy does not have polarity (I don't know what you mean by polarity---I know polarity of magnets, but not this).

Capiert you must first understand what's scalar and what's vector. Force and momentum are vectors because they involve scalar multiplication of vectors ( in force we have the multiplication of scalar mass and vector acceleration, and in momentum we have multiplication of scalar mass and vector velocity). But energy is not a vector. Also you are not clear about squaring and rooting. Any integer squared gives a positive integer. But, on extracting the square root we put a plus-minus sign before the number whose square we have rooted. And if we extract the square root of a negative integer we call that an imaginary number. [math]\sqrt{-1}=i[/math]

All these things are based on Archimedes' Principle, which states that when a solid body is immersed in a fluid, then it experiences an upward thrust which is equal to the weight of the volume of the fluid displaced by the immersed part of the solid body. The depth upto which a ship can be sinked is determined by some small calculations based on the above principle.

Hey zztop, you forget the limit. ;-)

By defining f(x)=x^2+3x or anything else, you can put its value in the equation and get the desired results.

I'm going through all the things........Just need some time.

[math]r=4\pi R^2[/math] ? But this rate must be time derivative.....here it is not so.

Yes. Energy in the form of photons.

There is nothing called indestructible.

r is constant but R is not. How do you relate r to surface area??

Electron transition releases energy. [math] E_2 - E_1 = hf [/math]

HAPPY NEW YEAR TO ALL MEMBERS OF SFN Hope there will be many more interesting discussions in this new year........ - Sriman :-)

So no energy is recorded.

Hi everyone, Suppose that there's an electron at rest removed from all gravitational sources and any other fundamental particles. There's an observer who is revolving around the electron at a distance of [math]d[/math]. But, due to lack of reference points, the observer cannot say with certainty that he is revolving or the electron is. He assumes that the electron is revolving. According to the Larmor's Formula, the observer will find energy being radiated out by the electron since he observes it revolving. But, how can the electron radiate out energy if it's not revolving? So, will the observer record no energy?

Ok thanks.
