Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and flies 680 m due east, then flies 430 m west, then 620 m east.

Susan's monthly energy usage is shown in the table. If it costs $0.20 per kWh, what will Susan's monthly bill cost? Round your answer to the nearest cent.

An engineer uses aluminum to build an airplane rather than composite materials that are lighter and stronger. He does this because he is concerned about the composite materials and how suddenly they can fail. This is an example of:

What does it mean to say that a material has a high specific heat?

How do mountins building and volcanos relate to plate motion at convergent boundaries

A 20kg box is dropped 13m. how much work is done

Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. Find the magnitude of the frictional force between the person and the wall

A ball is being rolled by a normal push of 1000N. it is opposed by friction which has a force of 0.3kN and air resistance which has a force of 23N. Calculate the resultant force.
