A proton (m = 1.67 x 10^-27 kg) is suspended at rest in a uniform electric field E. Take into account gravity at the Earth's surface, and determine E.
I did this problem already but I'm not sure if it's correct...
I used the equation: E = F / q = ma/e to get an answer of 1.02 x 10 ^-7...
A huge 4.0-F capacitor has enough stored energy to heat 2.5 kg of water from 21 degree Celsius to 95 degree Celsius. What is the potential difference across the plates?
What equation am I supposed to use for potential difference?
Is it V = Change in PE / q
V= - W / q...
I'm kinda stuck with these problems... can somebody please help?
1) What is the average distance between nitrogen molecules at STP?
I know that at STP: T=273K, P=1atm=1.013 x 10^5 N/m^2. How would I start solving this proble?
2) The lowest pressure attainable using the best available vacuum...
Hi I have this problem and I don't fully understand how to get started, so please help. Thanks
A bucket of water is accelerated upward at 2.4g. What is the buoyant force on a 3.0-kg granite rock (SG=2.7) submerged in the water? Will the rock float? Why or why not?
I know that it would...
