Question:
A cork floats on the surface of an incompressible liquid in a container exposed to atmospheric pressure. The container is then sealed and the air above the liquid is evacuated. The cork:
A. sinks slightly
B. rises slightly
C. floats at the same height
D. bobs up and down about its old position
Answer:
The correct answer is C) floats at the same height
Explanation:
The liquid is incompressible because its density very high and leaves no room for further compaction whether or not there is atmospheric pressure. So when you put a cork on the liquid, pressure or no pressure, there is no displacement hence it floats on the same height regardless of the absence of air.

Answer:
Distance, r = 3721.04 meters
Explanation:
It is given that,
Charges on both humans, 
Electric force of attraction between them, F = 650 N
We need to find the separation between two humans. It can be solved using the following formula as :
r = 3721.04 meters
So, the distance between the humans is 3721.04 meters. Hence, this is the required solution.
Floating. When you have no gravity you have nothing to be pushing you down to the floor so that would be an example of no gravity pushing on you.
