A large ship can float but a steel needle sinks because of:
A
viscosity
B
surface tension
C
density
D
none of these
Answer
none of these
Explanation
Solution
A large ship can float but a steel needle sinks, this concept is explained by Archimedes Principle which states that when a body is fully or part all submerged in a fluid, a buoyant force from the surrounding fluid acts on the body. The force is directed upward and has a magnitude equal to the weight of the fluid that has been displaced by the body.
