Homework Statement Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. The frequency of the waves emitted by each speaker is 172 Hz. You are 8.00 m from speaker A. Take the speed of sound in air to be 344 m/s. What is the closest you can be to...

I'm not actually sure. I just know that in a situation like this you can describe the pressure of a place in water as atmospheric pressure + the density*gravity*deepness of the point. I'm not sure what it would be for multiple layers

Okay I think I screwed up a little. The placement is till going to be at the top of the juice but this is the formula The formula for Bernoulli's when applied to this problem becomes this p1 + \frac{1}{2}\rho v_1^2 - \rho g d = p2 + \frac{1}{2}\rho v_2^2 - \rho g h_0 p_a +\rho gd - \rho...

h_0, where the juice is falling out

The top of the cranberry juice would make it easier I think.

What would those be? I know that you could make y1=0 ,but I'm not sure what else you could do.

Homework Statement Jane goes to a juice bar with her friend Neil. She is thinking of ordering her favorite drink, 7/8 orange juice and 1/8 cranberry juice, but the drink is not on the menu, so she decides to order a glass of orange juice and a glass of cranberry juice and do the mixing...

Homework Statement A small sphere with mass m is attached to a massless rod of length L that is pivoted at the top, forming a simple pendulum. The pendulum is pulled to one side so that the rod is at an angle θ from the vertical, and released from rest. When the pendulum rod is...

Ohhh, yes you're absolutely right. What was the point in throwing in the weight of the pulley then, extraneous information?

I don't think it should, I divided through by r to arrive at T=\frac{Ia}{rR} the division takes place in the line above the one you are citing

Homework Statement A block with mass m = 5.00kg slides down a surface inclined 36.9 ∘ to the horizontal (the figure (Figure 1) ). The coefficient of kinetic friction is 0.27. A string attached to the block is wrapped around a flywheel on a fixed axis at O. The flywheel has mass 23.0kg and...

Sorry that should be \frac{GMm}{R^2}=g_{europa} Which "technically" is still acceleration but that wasn't clear

Homework Statement There is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the...

Homework Statement A solid wood door 1.00 m wide and 2.00 m high is hinged along one side and has a total mass of 42.0kg . Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.400kg , traveling perpendicular to the door at 11.0m/s just before...

Oh! Yes, you are absolutely right that's a typo, F1 should have a negative value and F2 should be positive
