[@JRockTT]

I really appreciate the content! I just have a couple of comments: For the Pgas equation, maybe start with: Pgas = Patm + Pgauge => h < 0 Pgas = Patm - Pgauge For the Archimede's Principle at equilibrium: EF = B - Fg = ma = 0 => B = Fg pgV = Fgobj => V = Fgobj/pg Since we already know the weight of the object, we can just solve for Vdisplaced straight away! Also, at the Hooke's Law question, Hooke's Law describes the restoring force, which is pointing upward in this problem, in the opposite direction of Fg of the 60kg block.

[@jessicauseful]

Negative. He has plenty of videos on single topics, each with tons of practice problems. This particular chapter in the book has topics that all relate to one another. Doing a ton of problems where one builds upon the other is helpful. However, time stamps for certain problems would be helpful. I have a hydraulic lift problem for HW, so it would be helpful to be able to find that one quickly.

[@gaeylyisevictor7626]

pls create video for each sub topics...couldnt watch the video for 4 hours..

[@aryandasgupta3385]

Well you can watch it faster and I swear you will not see a difference plus it takes half the time

[@krish3919]

I am appreciative of the time and effort put into these videos. I have learned so much about multiple scientific disciplines. Thank you. I do want to pose a question to make sure I don't have a blind spot. At 3:46:05, the radii are considered in cm^2, yet the speed in the equation is m/s. If anyone understands, can they clarify? Because I am not sure whether velocity 2 should be greater or less than velocity 1 and it seems important since we are both losing height and losing volume. If I convert the radii to meters, I get .167 m/s, which is a big difference...and it's a lower velocity than velocity 1.

ok but at 45:10 to 45:20 shouldn't you have converted your area to m^2 instead of cm^2 , because remember the equivalence of the units of force N is kg.m.s^2 not kg.cm.s^2 ,so that 10 cm and 60 cm should they have been 0.1 and 0.6 instead , just asking ? will be glad if anyone clarifies my confusion

[@madou1666]

Hey I just noticed this as well. Normally you should, yes. However in this case it does give the same outcomes whether you'd calculate it back to msquare or keep it at cm square, because it is an devisional number and would be the same anyways.
