I'm very happy for Vector AB !
Lake Ontario is FRESH water and is LESS dense than the SALT water of the Atlantic.....
does that help you ?
Check out peole swimming in the VERY salty Dead Sea !
Conservation of momentum
.5(1.5) + .3(0) = (.5+ .3) vf
vf = .9375 m/s
A time = B time
1/a + 1/a + 1/c = 1/3 1/c = 1/12
2/a + 1/12 = 1/3
2/a = 1/3 - 1/12
2/a = 4/12 - 1/2
2/a = 3/12
1/a = 3/24
a = 24/3 = 8 hr
A high cohesion means the intermolecular forces are high.....the particles stick together
high adhesion means they also stick to other substances....
a very sticky slow moving viscous blob is what you wind up with ~!
One way is via displacement....
say you have a stone.....weight it
then place it in a graduated cylinder partially full with water and not the change in volume on the cylinder ....that is the volume of the stone
then density = weight/ volume
Missing some important info in your question.......
