Density is a physical property which plays a veryimportant role in our daily life. It is very widely used in allfield of engineering. Density is widely used for choosing thesuitability of a material for a specific purpose.
a) Discuss how density is finding its application inMarine engineering field in not more than 100 to  150words.
      b) Describe the way in whichyou can determine the density of given substances. Also explain thetools which are used for finding the density. Explain indetail.
      c)  You are given acylindrical shaped silver having diameter X cm and height Ycm.
             [ You can take X – the first two digits of your student ID and Y –the last two digits of your student ID. For e.g., If the student’sID is 1875-18, The X = 18 and Y = 75]. The density of silver is10.5 g/cm3. Calculate the mass of the silver shape given to you inkg/m3.
             [ for conversion you can use - 1 m = 100 cm and 1 kg = 1000 g]
