Displacement and Measurement
Question 1 (i). A car travels between city A and city B, a distance of 45miles at an average speed of 50 mph. on the return journey the average speed is 40 mph. Calculate the average speed for the total journey of city A to city B to city A.
(b). A chemical power plant is rectangular and has a length of 100 m and a width of 60,000mm. A safety zone of uniform width surrounds the plant. (i). If the area of the safety zone equals the area of the plant, calculate the width of the safety zone

While waiting to catch a commuter train, I was standing just inside the yellow safety line, about 1 meter from the platform edge. Little did I know that an Acela train was coming through without stopping. That train was moving at about 60 miles per hour (about 28 meters per second). Estimate the velocity in miles per hour that the wind from the train hit me, 10 seconds after the first car has passed. Suppose that I had stood back...

A) A new power plant is proposed for the Great Plains, the details are very sketchy, but the press release says it will heat water to 480 degrees Centigrade, then convert it to electric power, then the left over water will return it to the heating plant at 220 degrees Centigrade. What is the thermal efficiency of the plant, not even knowing HOW they are heating /cooling or converting the energy. B)One big historical use for wind power was water...

battle has erupted over a local power plant owner's decision to raise the power delivered by the plant from 242 MW to 689 MW (The delivered power accounts for energy losses). The local population is increasing, so the area needs more power. However, the plant expends its heated waste water* into the Frustration River, local citizens are concerned that the heated water will raise water temperatures to the point where the endangered river smelt will die from oxygen depletion. Local...
