Answer:
The tension on the string is
Explanation:
From the question we are told that
The mass of the rock is
The density of the rock is
Generally the volume of the rock is mathematically evaluated as
substituting values
The volume of the rock immersed in water is
substituting values
mass of water been displaced by the this volume is
According to Archimedes principle
=>
The weight of the water displace is
The actual weight of the rock is
The tension on the string is
substituting values
In the first case, the force acting on the spring is the weight of the mass:
This force causes a stretching of
on the spring, so we can use these data to find the spring constant:
In the second case, the first mass is replaced with a second mass, whose weight is
And since we know the spring constant, we can calculate the new elongation of the spring:
