What is buoyant force?
-
this video got me so confused
-
this is the famous q asked in jee in 90s
-
Sorry Guys. Only if the rock were pumice and therefore would float, would your understanding be correct. As the rock might be far more dense than water, lets say twice, the boat might displace twice the volume of the rock but as the rock sinks.

lower
-
what are the answers of those problems which were at the end of this video?
-
Another problem solved only by extremes, if's and maybe's.

Wow, Meg Chetwood is so beautiful! :)
-
what is the answers to the problems in end
-
Problem 1: if the two blocks show the same weight in the dome, the wooden one consequently has to sink when the a vacuum is created, because the amount of displaced air is bigger, thus if the supportive buoyancy is lost, the wooden block goes down . ?

2*10*2*pi longer

+Physics Girl - For problem 1 is the mass the same or the balance perfectly balanced - it cant be both and you say it is at ~ 3:30
-
But you haven't pointed out that the rock's density is higher than the boat XD
-
what about case if boat is really really big, and you are as small as rock would be to small boat, so you are just like human shaped rock..wouldn't it be same case as first one ??
-
the last questions answer should 2×pi×(r+10) where r is the radius of the planet
-
Someone please explain the last puzzle!!
-
So we should drown sailors to counteract rising sea levels (and appease Poseidon, obvs)

beautiful girl and physics....... rare combination.....you are gorgeous....

You throw a rock in water from your boat. Can you figure out what happens to the water level? physicsgirl.org instagram.com/thephysicsgirl facebook.com/thephysicsgirl twitter.com/thephysicsgirl Help us translate our videos! http://www.youtube.com/timedtext_cs_panel?c=UC7DdEm33SyaTDtWYGO2CwdA&tab=2 Host/Writer/Editor: Dianna Cowern With help from: Jimmy Wong https://www.youtube.com/user/jimmy Jake Roper https://www.youtube.com/user/Vsauce3 Meg Chetwood https://instagram.com/megatronvolley/ More information: http://people.umass.edu/~clement/pdf/NARST09ExtCasePaperLS.pdf
