2. A cell has a terminal voltage of 50.0 V for a current of 10.0 A, and 54 V for a current of 6.0 A. Find the electromotive force and internal resistance of the cell. 3. A compact fluorescent lamp (CFL) uses less energy than its equivalent incandescent bulb. How much will a person save if he/she uses a 20 W CFL instead of a 100 W incandescent lamp for 6 hours in 30 days? Electricity is prized at Php 8.17/ kWh?

You are the mechanical engineer supervising the layout of a piping system. In a certain portion of the pipe, the specifications are as follows: length of pipe is 10m, inside diameter of 30cm, outside diameter of 30.5cm, maximum allowable speed of 15m/s and a coefficient of 0.003456. If the uncertainties are 0.02mm for length, 0.8mm for the diameters and 0.1mm/s for the velocity, what loss of head will be imminent in this pipe? In the piping system above, what is the uncertainty in computed head loss contributed by the velocity of the pipe?

Problem: Insufferable Enlightenment era scientists are a lot like insufferable frat boys/sorority girls - they just cannot get enough of themselves. One of the most well-known "big brain" contests in their history was a Europe-wide challenge presented by a certain Swiss scientist called Johann Bernoulli (who already had his own solution so that he could pompously show off once the submissions came in). He asked the "leading minds of the world" the following: What is the curve along which a particle, under constant gravitational acceleration g, would descend from one arbitrary point to another within the fastest duration of time? Fancily called the brachistochrone problem (derived from the Greek word for just "shortest time"), Bernoulli's initial solution used the law of refraction as the result of applying the principle of least time to a light particle. Let's give this solution a shot ourselves. (a) Consider an initial point of (xo, 0), both parameterised by time t. Our goal is to…
