Question 2 1 pts Two identical objects Thing 1 and Thing 2 are dropped, starting from rest, from two different heights and fall to the ground. If it takes Thing 2 twice as long to hit the ground as is does Thing 1, what is the ratio of the heights from which Thing 1 and Thing 2 are dropped. Neglect air resistance and divine intervention. 1: $\sqrt{2}$ 1: 2 1: 8 1: 4

MCQ 8: A single-phase full-wave rectifier has an input voltage of 20 V (RMS). The frequency of the supply is 50Hz. A capacitor is used to smooth the output voltage of the rectifier. The rectifier now needs to supply a constant current of 5 mA to the load. The ripple has to be kept at 25 mV (peak). Calculate the value of the capacitor. (2) a) 4 mF b) 2 mF c) 1 mF d) 5 µF

A) Find the amount of heat by natural convection to the outside environment? Water flows at a flow rate of 10 lt/min through a pipe with a length of 5 meters and an inner diameter of 30 mm and kept at a constant temperature. Cold water enters the pipe at 15 $^\circ$C heats up and exits at 65 $^\circ$C. The outer diameter of the pipe is 34 mm and the radiation emission coefficient of the outer surface is 0.5 and the ambient air temperature in which the pipe is located is 30 $^\circ$C. Note: pipe material thermal resistance will be neglected. Get air fluid properties at ambient temperature, water fluid properties at inlet-outlet average.
