The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e=0.85 and the initial velocity 6 m/s.neglect friction.(teta=70 degrees)
Make a list of threats which may be vulnerable to the company's information system.
The dye appears 14 days later in an observation well 75 ft away from the injection point. Compute the seepage velocity and estimate the hydraulic gradient in the aquifer if the porosity of the soil is 42%.
Determine the normal depth in a trapezoidal channel with a bottom width of 6.4 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 85 ft3/s. Manning's roughness factor is 0.025 and the channel bottom slope is 0.001
Emissions of heat-trapping carbon dioxide (CO2) reached an all-time high of 31.6 gigatons in 2011, a 3.2% increase over 2010. The International Energy Agency said this further reduces the chance that the world can avoid a dangerous rise
