Coagulation of Proteins -- please help
We have a report tomorrow about this and I am not so sure of my results: (coagulation by heat)
Milk - no cloudy appearance, soluble in water
Egg white - with cloudy appearance, insoluble in water
Flour - no cloudy appearance, slightly soluble
I...
I think Triboelectric series is the reference here. But I do not know what happens when both rubbers are rubbed. Is it possible that they both gain positive charges?
Identify which of the ff. object will be positive or negative charge
1) Hand and Hair
2) PVC and Tetlon
3) Glass and Poly ester
4) Rubber and rubber
5) Hand and wood
I did the equation you have posted and here is what I got:
ΣT = F1 x 0 - W x c + F2 x d = 0
I canceled out "F1 x 0" since it is equal to zero.
So, ΣT = - W x c + F2 x d = 0
My value for W=162.8 lbs, for d = 59 cm and for c = 29.5 cm (I divided the d to get this value). Substituting these:
ΣT...
I tried to figure this out and this is what I have come up with:
Since the R and the F of the pool rungs are unknown, I cannot solve for the first condition of equilibrium. So, I used torque to solve for the forces.
(assuming the values are correct)
ΣT = Fx1 + Fx2 + Fx3 ...
Ah, so R(resultant vector) - lbs(weight of my teammate) - F(Force of the pool ladders) = 0
Therefore, I have to solve for the F first which is
F = R-lbs?
Is this correct? I'm so confused.
I do not know how to make a diagram but here is the link of our taken photo for our assignment:

I hope this helps. Thanks! :)
We were assigned to do a planking and then prove why it is in equilibrium by computing its torque, etc. We selected the pool ladder rail to do the planking. Our team member who did the planking weighs 74 kilos and 5'1" tall. The pool ladder rails are 1 m above the ground. Torque=Force x momentum...
We have a short film project in Physics about the role of Physics in our course. I am a pharmacy student and me and my 3 teammates tried to write a plot summary but our storyline is not that good.
Can you provide me with any ideas we can do for our project? Thanks!
