pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition problem. A figure is drawn with the vectors indicated. Here vb is the boat’s velocity (still water)‚ vr is the river’s velocity‚ and vnet is the resultant

Twain uses the Mississippi River in this story to place Huck on a figurative island separated from the influences of society. Twain uses this separation to allow Huck to develop his own opinions according to his own moral values. The river is used as a method of illustrating specific themes such as desire for security‚ freedom‚ and equal human rights.

If you were to take a random inhabitant of Los Angeles and ask them about the Los Angeles River‚ they would give you a confused look saying “what river?” Meanwhile‚ others will say “Oh‚ you mean the place with the shopping carts.” This is because most of the river has been blocked off over the centuries as more projects cover the river and more recently has become a haven for the homeless. The river has played a large role in the shaping and the history of Los Angeles‚ as the water that flowed from

State‚ for each of the following physical quantities‚ if it is a scalar or a vector: volume‚ mass‚ speed‚ acceleration‚ density‚ number of moles‚ velocity‚ angular frequency‚ displacement‚ angular velocity. Answer: Scalar: Volume‚ mass‚ speed‚ density‚ number of moles‚ angular frequency Vector: Acceleration‚ velocity‚ displacement‚ angular velocity A scalar quantity is specified by its magnitude only. It does not have any direction associated with it. Volume‚ mass‚ speed‚ density‚ number of

Finn‚ Huck lives in two different settings. One of the settings is on land with the widow and with his father and the other is on the river with Jim. There are many differences of living on land as opposed to living on the Mississippi River. On land‚ Huck has more rules to live by and he has to watch himself so as not to upset the widow or his father. On the river‚ Huck didn ’t have to worry about anything except people finding Jim. He also had to worry about the king and the duke for a while.

Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers
