they are NOT capacitors they are batteries, E1 and E2, and E3 are all batteries...

can anyone help with this problem please...

can anyone help me with this question please...

The questions says that it doesn't matter if the switch is open or closed. It asks, what is the emf E3 in terms of the other quantities shown. I have attached a diagram of the circuit. Thank you in advance.

I think open-closed (open being the ocean, closed being a rock shore barrier type of thing)

can anyone help me with this question?

Hard Wave Question (Really need help pleasez!) The Bay of Fundy, Nova Scotia, has the highest tides in the world. Assume that in midocean and at the mouth of the bay, the Moon’s gravity gradient and the Earth’s rotation make the water surface oscillate with an amplitude of a few entimeters and...

can anyone help me?

The graph shows the position x of an oscillating object as a function of time t. The equation of the graph is x(t)=Acos(wt + \phi) where A is the amplitude, w is the angular frequency, and \phi is a phase constant. The quantities M,N, and T are measurements to be used in your answers. See...

thanks you thank you thank you

So...final answer is F = \frac{-2msin\theta_{i}v_{i}}{(\Delta t)} ?

i don't know...i don't know how to set the three equations equals to one another...

so is the final answer just F = mv_{ix}/t

How come you need the three equations? why can't you just rearrange the Fx to get you F_{x}= \frac{mv_{xfinal} - mv_{xinitial}}{(\Delta t)} note: my mistake, the answer does depend on mv_{xi} but it does not depend on mv_{xf} so in light of this information, i guess i have to ask you...
