SSteve4Physics replied to the thread Phase relation between two waves.Say we have a transverse wave, moving in the +x direction, along a string. There are 2 very different types of graph and it’s easy to...

SSteve4Physics reacted to haruspex's post in the thread Struggling to understand the concept of this question (ice cube in water optics question) with
Agree.
Wouldn’t that make the height seem greater? -
SSteve4Physics reacted to berkeman's post in the thread Egg Drop Challenge! Need ideas for winning designs with
Haha.
My wife's work had a team building exercise one year where they were supposed to build miniature soap box derby style gravity cars and... -
SSteve4Physics reacted to jbriggs444's post in the thread I've come across another fluid pressure problem I don't understand with Agree.
I do not disagree with this at all. If we are working with absolute pressures and ignoring surface tension then water pressure is always...

SSteve4Physics replied to the thread I've come across another fluid pressure problem I don't understand.Yes. Post #26 was intended for the OP - in case they didn't understand the underlying physics. My school physics teacher (from many...

SSteve4Physics replied to the thread I've come across another fluid pressure problem I don't understand.You may have some misundestandings - even about the forces in Fig. 1. Try working through this: Consider the simple Fig. 1 setup...

SSteve4Physics reacted to jbriggs444's post in the thread I've come across another fluid pressure problem I don't understand with Agree.
For a massless piston assembly subject to no external forces other than water pressure, the calculation for ##F_3## is immediate and...

SSteve4Physics replied to the thread I've come across another fluid pressure problem I don't understand.Some general comments... Units for ρ and g are essential. If the correct units aren’t clear, sometimes terrible things happen! E.g. see...
