Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

To demonstrate thermal expansion/contraction we saw a video clip with a sphere and ring (like the ones pictured here). The ring was dipped in liquid nitrogen, and then the sphere would no longer fit through it. What could now be done to the sphere so that it would fit through the ring again? O Dip the sphere in liquid nitrogen. O Use a blowtorch to heat the sphere up. O Nothing can be done to the sphere, only the the ring can be altered. O Put oil on the sphere to make it slippery.
1. Suppose identical solid spheres are distributed through space in such a way that their centers are lie on the points of a lattice, and spheres on neighboring points just touch without overlapping. (Such an arrangement of spheres is called a close-packing arrangement.) Assuming that the spheres have unit density, show that the density of a set of close-packed spheres on each of the four structures (the "packing fraction") is: fcc: bcc: √√2/6=0.74 √√3/8=0.68 SC: π/6=0.52 √√3/16=0.34 diamond:
