I'm sorry for not being very clear. Actually, it was stated in the question that Q is the centre of AB. So, is the friction acting ALONG the surface PA ( either upwards or downwards)?

Homework Statement The original question was to find the value of the angle between PA and AB. I have a certain idea regarding how to find it, but first I have to identify all forces acting on the system and their directions. So, I would be grateful if someone can explain how the frictional...

Can you please kindly explain further the above situation you are referring to? Thank you.

Then Vx:Vy should be 1:2

What you have said is correct but, here it is not the case. It is true that if a certain flow has enough kinetic energy to overcome the pressure gradient, it will move from lower pressure region to higher pressure region. Then its mechanical kinetic energy will be converting to potential energy...

If there's no pressure gradient across a tube, how will the flow inside be maintained?

2Vx=Vy. So , if the value of Vx is 1, value of Vy should be 2 right?

Indeed. Vy/2=Vx , so Vx: Vy should be 1:2 because then Vy÷2=1.

Nothing seems wrong with your calculation. Answer should be 2:1. But books sometimes give wrong answers.

As to your answer that displacement at X is zero, it is correct. But the displacements at Y and Z are also zero. How can this be? The reason is that both compressions and as well as rarefactions are corresponding to zero displacements. When you say the displacement is zero, the distance from...

You are correct when you say that the mechanism of blood flow in capillaries and arteries is similar to the above scenario. But Bernoulli's principle cannot be directly applied to this situation because in order to apply Bernoullis principle, volume flow rate should be constant throughout the...

I think you are confused about few things here. 1) The velocity increases in a funnel due to conservation of mass. Mass conservation means that the mass flow rate in the tube, should be constant at any point inside the tunnel. Mass flow rate can be given as the product of density and volume...

Yes, that seems wise.Thank you.

Yeah,I guess that's what I'll do. Anyway thanks for helping.

My physics lecturer gave the answer as 3 Celsius .
