Course help! Could PLZ on help on one thing. I don't know wot the following are and how they incorperate into my work course which is about meauring the depth of water in a tank using sound waves and messuring the time delay ogf the reflected wave. Resolution response time systematic bias or...

I'd be very grateful to someone who could help me out here. I just started Biology and I'm having a hard time knowing how to calculate micrometres. It wasn't really explained well. Anyway I've started out by estimating the width of a human muscle tissue cell in Centimetres. I got about 50...

Here's the problem: To measure the heat capacity of an object, all you usually have to do is put it in thermal contact wit another object whose heat capacity you know. As an example, suppose that a chuck of metais immersed in boiling water (100 degrees), then is quickly transferred into a...

Can beauty be measured? in any way shape or form? even if its subjective to one person's ideas... can it still be measured? Or is beauty an abstract sort of thing that one cannot put a value on?

Can anybody tell me why it is better to use a burette rather than a measuring cylinder.

This is a repost from the general physics forum, as I didn't see the homework help forum before I posted in the other place. Anyway, I did an experiment last week in my college physics class where we measured the wavelength of a laser light using single, double, and multiple slit...

I did an experiment last week in my college physics class where we measured the wavelength of light using single, double, and multiple slit diffraction and diffraction grating. Using the measurements and Young's equation, we calculated the wavelength of the light. My teacher said that as we...

the self-capacitance and self-inductance of a coil? Are there equations for these where I won't need to know the number of turns? Since I think #2 is no, are there meters I can buy to measure this, or can I use the measurements from a volt/resistence meter I already have?

For a particle with S = 1 in a state of Sz = 1, what are the probabilities to obtain the various values of the spin component if measured along a direction which makes an angle Q relative to the z-axis? Is there a general method for an arbitrary value of S?

What is the official count of one second? What I mean by this is: how would one go about measuring one second exactly? Basically, at the creation of a second, how was it measured? Also, if a day is 23 hours and 56 minutes, wouldn't our clocks be off 4 minutes after each day? I understand the...

How many points are there on the Beaufort scale for measuring wind force?

If a ray of light was capable of grabbing the end of our tape measure as it passed us, it could prove to the world once and for all that the speed of light is not the same for observers at different velocities. Consider the following: Imagine we are observing a ray of light that has a...
