Im standing in the middle of the U.S. I have a harness around my waist with a featherlight pipe with a ball on the end which extends to New York City. I spin around in a circle which takes 2 seconds........this means, the ball on the end flew over Canada, whizzed over California, blazed over Mexico, and returned to New York City in 2 seconds. Can you explain this?

I would like to know best way to get exact temperature within +- 5 degrees, I thought of putting in boiling water ( 212 degrees ) but not sure if water stays at 212 or gets hotter. This is for a smoker which needs to be at 200 to 225 degrees.tnx

I think that capacitor decay is a random process since it is very similar to radioactive decay but one person is trying to prove me that it is not I can’t find an answer in search engine may be you know it?

I have two scenarios. The first is a 60 W bulb and a 100 W bulb that are both separately connected to a 120 V outlet. Which one is brighter using math/physics?

The second scenario is both bulbs are connected in series starting with 120 V then the 60 W then the 100 W then back to the 120 V source. Which one is brighter on this using physics and math?

Given that V = 10.00 V and R = 5.000 ohms, can you determine the size of current through the resistor 2R. You may use whichever method you like but I want to see how many people can do it with kircchoff's rules.

Given that
V: = 16.00 V
R2 = R3 = R5 = 4.000 ohms
R6 = 6.000 ohms

find the currents through the four resistors and ammeter in the following circuit:

When white light passes through a glass slab then no spectrum is seen after the light comes out of the slab although it refreacts different colors of light to different extends but in the case of a prism this happens........we r able to see a spectrum of 7 colors.........Why is it so???????

Theoritically it has been assumed that If a PERSON on earth sees the space-ship which is travelling at near-to-light speed relative to earth, then the space-ship wpuld be seen in a SLOW MOTION(TIME SLOWED DOWN) . Wheareas if the person on the SHUTTLE sees the person on earth then, to him it appears that the fellow on earth is in a fast-forwarded motion......So what is the reason behind this?????!!!!!!!!!

Which is not correct when describing the formation of rainbows?
A rainbow is really spherical in nature.
Sunlight is spread into a spectrum when it enters a spherical raindrop.
Sunlight is internally reflected on the back side of a raindrop.
All wavelengths refract at the same angle.

=> When I connect one side of a lamp to the positive terminal of a battery (or one pin of an electricity outlet in my house), and I connect the other side of the lamp to a grounded rod, will the lamp light up? Why (not)?

I know that one of electricity's basic rules is:
In order for current to flow, you need a closed circuit (so electrons can flow from one side to the other).
So my gut feeling says no, but then again I made this reflection that bothers me:

they say earth attracts electrons. For example: when I touch a static charged object (or an AC live wire, 1 phase), current will flow through my body to earth, right?
In this case there's isn't really a closed circuit, is there? (I'm only toughing 1 phase).
So why shouldn't the lamp light up??

Thanks for sharing your reflections

If I travel in a vehicle at lightspeed, I can walk to the front of my vehicle. That means I move faster then the speed of light, or not?? Then: if I can, I can overtake the light and look in the past or not?
