A 5.00 kg rock whose density is 4300 kg/m3 is suspended by a string such that half of the rock's volume is under water. You may want to review (Pages 370 - 372) . For help with math skills, you may want to review: Conversion Factors Part A What is the tension in the string

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

their crystal patterns have been disrupted by stress
