A Carnot engine operates between a high$-$temperature reservoir at $500$ K and a low$-$temperature reservoir at $300$ K$.$ If the engine absorbs $600$ J of heat from the high$-$temperature reservoir, calculate the efficiency of the engine, the work done by the engine, and the heat rejected to the low$-$temperature reservoir.Water flows through a pipe with a diameter of $0\mathrm{.}1$ m at a velocity of $2$ m$/$s$.$ The pipe then narrows to a diameter of $0\mathrm{.}05$ m$.$ Using the principle of continuity, calculate the velocity of water in the narrower section of the pipe and the mass flow rate of water through the pipe.A steel rod with a length of $2$ meters and a cross$-$sectional area of $0\mathrm{.}01$ m$^2$ is subjected to a tensile force of $50,000$ N$.$ Calculate the stress in the rod, the strain in the rod if the Young$$s modulus for steel is $200$ GPa, and the elongation of the rod.A block of mass $10$ kg is sliding down an inclined plane with an angle of $30$ to the horizontal. The coefficient of friction between the block and the plane is $0\mathrm{.}3.$ Calculate the acceleration of the block, the net force acting on the block, and the distance traveled by the block in $5$ seconds.A flat plate of area $2$ m$^2$ is exposed to solar radiation. The solar irradiance is $800$ W$/$m$^2.$ If the plate is made of a material with an absorptivity of $0\mathrm{.}6,$ calculate the total solar energy absorbed by the plate per second and the temperature rise of the plate after $10$ minutes if the specific heat capacity of the material is $900$ J$/$kg$$K and the mass of the plate is $5$ kg$.$
