There is a diagram in my book for this problem... I'll try my best to describe it! There are two speakers (A & B) that form a right triangle (at B) with the listener (C). Suppose that the separation between speakers A and B is 5.00 m and the speakers are vibrating in phase. They are playing...
I'm stuck on a entropy problem and have no idea how to solve it!!
Heat Q flows spontaneously from a reservoir at 394 K into a reservoir that has a lower temerature T. Because of the spontaneous flow, thirty percent of Q is rendered unavailable for work when a Carnot engine operates between...
Thanks Andrew! When I used 3 significant figures, I calculated that the volume of the cavity is 4 x 10-6 m3, which is the correct answer. Thanks again!
I'm stuck on a practice problem for physics (and I have a test tomorrow afternoon!)
A small sculpture made of brass (ρ = 8470 kg/m3) is believed to have a secret central cavity. The weight of the sculpture in air is 15.76 N. When it is submerged in water, the weight is 13.86 N. What is...
I have two physics problems on fluids that I'm stuck on and would appreciate any help! This is an algebra based physics class... (no calculus).
1. A solid cylinder (radius = 0.150 m, height = 0.120 m) has a mass of 7.00 kg. This cylinder is floating in water. Then oil (rho = 725 kg/m^3)...
