Herman Trivilino replied to the thread Magnitude of buoyant force in fluids of different densities.Okay. The instructions in 1 prompt us to rank the cars, not the relevant property (time) of the car's journeys. Prompting us for a... -
Herman Trivilino replied to the thread Magnitude of buoyant force in fluids of different densities.If the authors meant rank the fluids that's what they should have written. Not "rank the densities". Density is a property of a fluid...

Herman Trivilino replied to the thread Magnitude of buoyant force in fluids of different densities.That's the version that appears in the textbooks. I also assume it's true. You mean that water would be in a state of neutral buoyancy.

Herman Trivilino replied to the thread Magnitude of buoyant force in fluids of different densities.That's not worded correctly. It should be asking you to rank the magnitudes of the buoyant forces. Clearly, the densities are not all equal.

Herman Trivilino replied to the thread High School Why is the constant speed of light so unique?.You could, for example, have a way of measuring the pressure such that you can identify the location of a high pressure region (a wave...

Herman Trivilino replied to the thread High School Why is the constant speed of light so unique?.Yup, I agree. I bungled it up. I was trying to make the statements of the speed of light to that of sound as comparable as possible, but...

Herman Trivilino reacted to A.T.'s post in the thread High School Why is the constant speed of light so unique? with
Like.
I find this comparison confusing: - For sound you talk about "moving relative to the wave". (Whatever that means) - For light you talk... -
Herman Trivilino replied to the thread High School Why is the constant speed of light so unique?.Oh, yeah. What a flub. I fixed it.

Herman Trivilino replied to the thread High School Why is the constant speed of light so unique?.I don't know. But here is the full quote ... Sorry if it's repititious. Okay, thanks for letting me know. I made an edit.

Herman Trivilino replied to the thread High School Why is the constant speed of light so unique?.I should have described your motion as being relative to the medium rather than relative to the source. What's the source? If you're...

Herman Trivilino replied to the thread Correct statement about size of wire to produce larger extension.No. It was my misunderstanding.

Herman Trivilino reacted to Steve4Physics's post in the thread Correct statement about size of wire to produce larger extension with Like.
No. The shape of a stress-strain graph doesn't depnd on the wire's diameter. So the breaking stress and strain are 'constants' for the...

Herman Trivilino replied to the thread Correct statement about size of wire to produce larger extension.But ##\epsilon_{max}## depends on the wire's diameter, no?

The given answer does not require exact linearity.

Herman Trivilino replied to the thread Correct statement about size of wire to produce larger extension.No, I don't think so. Glass has some elasticity. You could witness this, for example, by reflecting a beam of light off the surface of a...
