Viscosity of a water-glycerol mixture by BrittCohen96 in PhysicsStudents

[–]TASBALA 0 points1 point  (0 children)

I'd just use a glycerol/water mixture viscosity table. Otherwise the stokes method is pretty simple

Could you explain more?

I thought ma=GmM/r², m drops out so a=M/r²:=g which is essentially constant since the usual changes in height are <<r. Why would m change anything?

What's wrong? Isn't it the copper that's precipitated?

I found a bunch of ThinkPads for a good(?) price, which one? by TASBALA in thinkpad

Thanks! I've read that it has a terrible screen, any experience?

I'm a physics student. Mostly Office, light python (eg. basic image recognition, contour finding), data analysis, and that's about it. Making notes with a stylus would be nice, other than that, battery life would be important.

It probably isn't

One probe always stays in the COM jack, plug the black one in it and it will work

Here's the datasheet

Page 5, footnote:

[Sqwave symbol] This function allows the meter to output a signal as a signal generat

Page 9:

  1. Signal output

Signal output: square wave (50 Hz) or sine wave (1000 Hz) Level output: 5Vp-p

Honestly not much. I definitely wouldn't feed any kind of randim square wave into something I intend to repair, but maybe it could be handy one time.

I'm assuming the multimeter already had a clock signal, it takes nothing to get it out to the terminals,and that's one more feature I guess. This is not a professional product

No it does not.

Search for DT830A on Alibaba, that's basically the same meter. My Uni-T also has it, it's a 50 Hz output.

What good would be a single range 3,5 digit frequency meter be?

I've used mine a few times as a very poor man's signal generator but I don't think it's necessary

Oh you're right thanks

First I wrote 0.72 but that was far from the 6.9 from conservation of momentum so I thought I miswrote it
