A pH scale goes from 0 - 14.
7 is in the middle so it is neutral
IT IS EASIER TO CLIMB A SLANTED SLOPE
Hold on and let's discuss this realistically.
Because of gravity, there are two forces between the Earth and me. One draws me toward the Earth. The strength of that force is what I call my "weight". The other force draws the Earth toward me, and has the same strength.
The strength of these forces depends on the masses of the Earth and me. If the strength just tripled, that means that at least one of us just picked up a lot more mass. If the Earth suddenly became three times as massive, then the weight of everything and everybody on it would suddenly triple, and I'm pretty sure it would be the end of all of us before too long.
If it was only MY mass that suddenly tripled, that would mean that I had gone tearing through my house and the neighbour's house, eating everything in sight including the 2 couches, 3 dogs, and 6 TVs. Naturally, just as you would expect, my weight changed from 207 to 621, and my skin is stretched really tight.
ooohhh
#1
As we know that
now plug in all data into this
now from the formula of strain
#2
As we know that
pressure * area = Force
here we know that
now force is given as
#3
As we know that density of water will vary with the height as given below
here we know that
now density is given as
#4
as we know that pressure changes with depth as per following equation
here we know that
now we will have
here we will have
so it is 20.1 m below the surface
#5
Here net buoyancy force due to water and oil will balance the weight of the block
so here we will have
so it is 3.48 cm below the interface
Hmm, I will come back to this one just to help. :)
