Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

(a) A iron block with a mass of 6.9 kg initially slides over a rough horizontal surface with a speed of 9.0 m/s. Friction slows the block to rest. While slowing to rest, 85.0% of the kinetic energy of the block is absorbed by the block itself as internal energy. What is the temperature increase of the block? (Enter your answer in degrees Celsius.) ?°C (b) What happens to the remaining energy? It is absorbed by the horizontal surface on which the block slides. It vanishes from the universe. It becomes chemical energy. It is so minute that it doesn't factor into the equation.

Consider a disc of mass M with a radius of 0.5 m that is lying on a slope at a 45-degree angle to the horizontal. It grips the hill well and does not slide. The disc is designed in such a way that its mass per unit area, (r), equals r1/2 kg m2, where r is the disc's radial distance in metres from its axis. Calculate the disk's mass.
