Answer:
The feeling of weight is one of compression.
Explanation:
All your body is being pulled down by gravity yet your feet ( if standing) or your back or something is holding you up.
Your body is compressed by the PAIR of forces and it is that compression that you feel.
So when you remove the supporting force then all the body is free to move together and there is no compression within you.
Hence you perceive no weight.
Because ice is less dense than liquid water,
its melting point is lowered under high pressures.
A long standing theory says that this is what causes ice to be slippery:
As you step on it, the pressure of your weight causes the top layer to my into water.
Answer:
<u>6.87 ft/s</u> is the rate at which the top of ladder slides down.
Explanation:
Given:
Length of the ladder is, 
Let the top of ladder be at height of 'h' and the bottom of the ladder be at a distance of 'b' from the wall.
Now, from triangle ABC,
AB² + BC² = AC²
Differentiating the above equation with respect to time, 't'. This gives,
In the above equation the term 
is the rate at which top of ladder slides down and 
is the rate at which bottom of ladder slides away.
Now, as per question, 
Plug in 
in equation (1) and solve for 
. This gives,
Now, plug in all the given values in equation (2) and solve for
Therefore, the rate at which the top of ladder slide down is 6.87 ft/s. The negative sign implies that the height is reducing with time which is true because it is sliding down.
