Caplets are used to support a sand core inside a sand mold cavity. The design of the caplets and the manner in which they are placed in the mold cavity surface allows each caplet to sustain a force of 45 N. Several caplets are located beneath the core to support it before pouring; and several other caplets are placed above the core to resist the buoyancy force during pouring. If the volume of the core = 5450 cm3, and the metal poured is steel, determine the minimum number of caplets that should be placed (a) beneath the core, and (b) above the core (Sand density = 1.6 g/cm3, steel density = 7.82 g/cm3).

In his experiment to test whether the crown of the King of Syracuse was made of pure gold or not, Archimedes immersed the crown into a container filled with water. He noted that the crown displaced 150 mL of water. If the mass of the crown is 2675 g, is it made of pure gold? A storage tank that is 15 m high is open at the top and initially filled with water. It developed a hole 12 m below the surface of water along its side. (a) What is the initial speed of water through the hole? (b) How far from the base of the tank will the water stream strike the ground?

(About measuring specific heat capacity) Since metal sample can be heated to any desired temperature value, say, 65°C or 156°C. Why is it practical to set the initial temperature of the metal sample near the boiling point of water? In connection to this, why should the dipper be partly submerged in the water while heating the metal sample?
