BUOYANCY

Buoyancy is the ability of an object to float. Archimede's Principle states that the buoyant force is equal to the weight of the fluid that is displaced by the submerged object. The buoyant force can be computed by:

buoyant force = (object volume) times (specific gravity of the fluid)

If the buoyant force is greater than or equal to the weight of the object then it will float, otherwise it will sink.

Write a program that inputs the weight (in pounds) and radius (in feet) of a sphere and outputs whether the sphere will sink or float in water. Use 62.4 lb/cubic foot as the specific weight of water. The volume of a sphere is computed by (4/3)π times the radius cubed.

INPUT and PROMPTS. The program uses this prompt ""Input weight of the sphere in pounds." for the first number it reads in, the weight of the sphere. The program uses this prompt "Input radius of the sphere in feet." for the second number it reads in, the radius of the sphere. Do not print out these numbers as they are read in

OUTPUT. The program either prints out "The sphere will float in water." or "The sphere will sink in water.".

Bourgeois states that it might be true that an artist has “something in them that either refuses or is unable to grow up.” What do you think she means by this?

What are the sorts of ideas she is dealing with here: politically, morally, poetically and/or psychologically? What is her message? Is she successful in getting her ideas across?

Create a graph and then set initial and goal states such that the number of nodes visited for BFS is smaller than that in DFS. Now modify the initial and goal state such that the number of nodes visited for BFS is larger than that in DFS.

Bonds issued by United Aerospace Corp. are publicly-traded. The bonds will mature in 15 years and have a coupon rate of 8 percent. If the market rate of interest increases, then the:

Multiple Choice

• current yield will decrease.

• coupon rate will also increase.

• yield to maturity will be less than the coupon rate.

• coupon payment will increase.

• market price of the bond will decrease.

According to Max Weber's definition of a state/sovereign i.e. "Something is a state/sovereignty if and insofar as its administrative staff successfully upholds a claim on the monopoly of the legitimate use of violence in the enforcement of its order" Would you argue that the United Nations is considered a state? what aspects of the UN would you argue don't fit Weber's framework and which do?

Why has the United Nations been unable to become a world government? What aspects of its organization and form make it impossible/difficult? What aspects of it seem like a world government? What would have to change in its organization or the way the world likes at it to make it a world government? What stops it, if anything, from making those changes?  

Goal 3 of the United Nations Sustainable Development Goals (SDGs) is to “ensure healthy lives and promote wellbeing for all at all ages”.
