Q2. A piece of concrete measures 4 ft by 4 ft by 1.25 ft. (a) What is its weight? (b) Find the buoyant force that acts on it when it is submerged in water. (c) What is the net force on the concrete piece when it is under water?

Q3. There are 6.3 multiplied by 10^28 mobile electrons per cubic meter in tungsten. The cross-sectional area of the tungsten filament in bulb B1 is 0.01 mm2 (1 mm2 = 1 multiplied by 10^-6 m2). The electron mobility in hot tungsten is 1.7 multiplied by 10^-4 (m/s)/ (N/C). Estimate the magnitude of electric field inside the tungsten filament in bulb B1.
