I've become a bit stuck on a question involving the charge transferred to a soap bubble as it's momentarilly connected to a potential V. I calculated the pressure difference between the atmosphere ...
There is an experiment we learned from high school that demonstrated how atmosphere pressure worked. Fill a cup of water and put a cardboard on top of it, then turn it upside-down, the water will not ...
Can water pressure ever become high enough to trap gas bubbles and/or keep them from surfacing?
The phenomenon where water flows on the outside side of a teapot spout is named "The teapot effect", and occurs due to a difference in pressure between water and the atmosphere. Consider the image of ...
I read the answer for the question Why is a hot air balloon “stiff”? and thought something sounded ridiculous. My engineering requirement is that the walls be strong enough. Here $T$ will be the ...
