Hi everyone! Not sure if this is the right place, but here we go: I am layman when it comes to physics, so I might be overthinking this completely, but I need to make sure that the physics stack up before I do the actual pipes etc. I have a 1000-litre water tank and below it I have a smaller...

I've been considering some questions related to the properties of silicon carbide used in stealth fighter jets, which is known for its ability to absorb electromagnetic waves. Firstly, I would like to know if it is possible to have a sealed iPhone inside a 60cm water tank (using a Ziplock bag...

A typical UK domestic hot water tank holds c. 200 litres of water. Hitherto the common method of heating it to say 60C has been by means of an internal coil of copper pipe through which is pumped hot water from a gas boiler at ~ 70C. Heat transfer on the outside of the coil is by natural...

I draw this diagram: The formula for hydrostatic pressure is: ##P=\rho g h## so I just plug everything $$P=1000 \times 9.8 \times 0.1=980 Pa$$ Will the acceleration of the cart affect the hydrostatic pressure? Another thing that came to my mind was there would be extra force coming from...
