What is the true option
Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…
Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…

SHOW YOUR SOLUTIONS PLS, THANKS show me how you did it so I can understand, thank you. Pls answer both, this is my last tutor question, pls. thank you. (Porosity). A dry rock weighs 240 grams and has a bulk density of 2.4 grams per cubic centimeter. When saturated with pure water at room temperature (T=25°C), it weighs 250 grams. At room temperature, the specific volume of water is 1.00295 x10-3m3/kg. Calculate the porosity of the sample. (Permeability). A cylindrical core sample of 1 cm length and 1 cm2cross-section has upstream and downstream pressures of 2 atm and 1 atm, respectively, during steady state flow of water at 0.997 g/s at room temperature. Calculate the permeability of the core. Note: Water @ 25°C, viscosity = 1 cp, density of water = 0.997 g/cm3.
