Two apartment buildings are built 50 metres apart. The angle of elevation and depression from the smaller building to the taller building are shown. Determine the height of each building.     

If the atmospheric pressure is [Psurface] kPa, what is the pressure in the ocean [d1][d2] m below the surface? Answer in the unit of kPa. Use 1027 kg/m3 for the density of the ocean water and g = 9.8 m/s2 for the acceleration due to gravity. Be careful with units.

Suppose the top of a dangling chain of length 5 meters is half way down the side of a 30 meter building and has a mass density of 20 kg/m. Find the amount of work (in Joules) it will take to haul the chain up the side of the building to the roof.  Assume the acceleration due to gravity is .

The graph of which of the following polar equations is shown below?  

Consider the convergent series

Suppose the top of a dangling chain of length 10 meters is half way down the side of a 40 meter building and has a mass density of 6 kg/m. Find the amount of work (in Joules) it will take to haul the chain up the side of the building to the roof.  Assume the acceleration due to gravity is .

Piper has sued Debbie, alleging that she was run over by a speeding car driven by Debbie. Piper was unconscious after her injury. Accompanied by Hunter, her husband, Piper was brought to the hospital in an ambulance. At trial, Piper calls an emergency room physician to testify that when the physician asked Hunter if he knew what had happened, Hunter, who was upset, replied, “I saw Piper get run over two hours ago by a driver who went right through the intersection without looking.”Is the physician’s testimony about Hunter’s statement admissible?
