A hollow spherical iron shell floats when completely submerged in water. The outer diameter is 60.0 cm, and the density of iron is 7.87 g/cm3. Assuming the density of water to be 1 g/cm, find the inner diameter of the shell.

Compared to conventional offenders, relatively few white collar criminals have been sent to prison.         

A river 5 m deep and 10 m wide splits into two equal streams, each still with 5 m deep but now 3 m wide. If the velocity in the streams is 5 m/s, what was the velocity (in m/s) of the original river?

A certain wire of length 2.0 m and radius 0.5 mm compresses by 0.2 cm when outward forces with total magnitude F= 20 N are applied to the ends. What is the Young’s Modulus of the material of the wire? Report your answer in 1010 N/m2

A wood plank of length 8m leans against a frictionless wall. The bottom of the plank is placed 2 m from the base of the wall. If the magnitude of the force of static friction that keeps the plank from sliding down is 93 N, what is the weight of the plank?

   At a temperature of 1000K, when equilibrium is established in chamber 1 for this reaction:   2SO2(g) + O2(g)   ⬄  2SO3(g)  DH = -197.78 kJ/mol   The quantity of each gas in the system is SO3 = 1.00 x 102 mol, SO2 = 4.15 mol, and O2 = 2.07 mol and the volume of chamber 1 is 10.0L. The pressure on the contents is increased so that the volume in chamber 2 is 1/10 the volume in chamber 1.  The temperature is maintained at 1000 K. You must list any equations used, show your work, and all numbers must have units. Significant figure and rounding rules apply.    e. How do the Kc’s in chamber 1 and 2 relate? Explain and type your answer below.
