find the apparent weight of a 54-kg person in the roller coaster as it passes over the top of the hill. The apparent weight is how heavy the person feels, which is determined in this case by the normal force.
A 10 cubic foot tank is initially evacuated and is then filled from a supply line which contains R-22 at 100 psi, 100 F. Assuming no significant heat transfer.
The atmospheric sulfur dioxide (SO2) concentration over a certain region is 0.12 ppm by volume. Calculate the pH of the rainwater due to this pollutant. Assume that the dissolution of SO2 does not affect its pressure.
R-22, flowing steadily at 70 lbm/hr, enters the expansion valve of a refrigeration system as a saturated liquid at 183.09 psia. At the exit of the valve, the pressure is 31.162 psia.
The coefficient of kinetic friction between the two blocks is 0.300, and the surface on which the 8.00 kg block rests is frictionless. A constant horizontal force of magnitude F=10.0 N is applied to the 2.00 kg block, setting it in motion.
If you were given a large data set such as the sales over the last year of our top 1,000 customers, what might you be able to do with this data? What might be the benefits of describing the data?
Give an example of a research/statistic study that you encountered this week in your life (outside of this course). This could be something your saw on the news, read about in another course, read in a magazine, or even online. Label the variables
For steady state conduction with no heat generation drive the radial temperature characteristics as a function of the radial distance from the center of the cylinder. Plot this characteristics as a function of the radial distance r.
