palaphys reacted to kuruman's post in the thread Missile with Coriolis force, air resistance and variable gravity with
Like.
Why is gravity in the ##\mathbf{\hat k}## direction? Don't forget that the Earth is approximated as a perfect sphere and "up" is the... -
palaphys reacted to div_grad's post in the thread Electrostatics - given V, find rho and Q with Like.
@Rick16 The way you calculated divergence is correct when you assume that ##r \neq 0##, but this means that you have to exclude the...

palaphys reacted to kuruman's post in the thread Apparent contradiction in a simple circuit with Like.
Let's take a few more steps back and apply the two basic conventions about ideal DC circuits: Batteries maintain a constant potential...

palaphys reacted to berkeman's post in the thread Apparent contradiction in a simple circuit with Like.
Since the voltage across each resistor is 4V, what is the current in each of the outer branches? And those currents add to make the 2A...

palaphys replied to the thread Apparent contradiction in a simple circuit.so there was no contradiction, and I wasn't wrong with my diagrams, just a silly conclusion which I overlooked. Thanks, I got it

palaphys posted the thread Apparent contradiction in a simple circuit in Introductory Physics Homework Help.So I came across this simple looking circuit, and it seems to me that the uppermost branch and lowermost are parallel w.r.t AB. applying...
