Answer:
more than 90%
Explanation:
In the unknown liquid the buoyant force and weight relation is

It can be seen that if the density decreases the buoyant force decreases.
If the object is already 90% submerged in water then, if the other liquid has density less than that of water the object will be submerged more than 90%.
Answer:
The nuclei are moving fast with respect to one another
Explanation:
Protons are found in the nucleus together with the neutrons while the electrons normally revolve round it.
However the protons appears fused in a way when electromagnetic force is applied by the nuclei moving at a very fast speed. This fast speed helps to keep the supposed neutrons fused together.
