Complete each statement about the sign of the work done on a baseball. Carlton catches a baseball and his hand moves backward as

dezoksy [38]

Answer and Explanation:

The work done is negative as the force is applied in the forward direction and the displacement of the hand is in the backward direction.
The work done is positive as the work is done on the baseball by Carlton. Moreover, both the force applied and the displacement of Carlton are in a straight line in the forward direction.
The work done in this case is zero as Carlton rides with constant speed, the Kinetic energy too remains constant and hence net work done is zero.
The work done in this case is positive as the work is done on the baseball by Carlton and as the velocity changes its Kinetic energy also varies wit it.
Also the force applied and the displacement of Carlton in this case are in the directed to the same path.

Imagine that you're standing in a large room when a loud noise is made. You begin hearing a series of echoes. Which characterist

german

The characteristic of sound that would best explain the series of echoes you are hearing would be reverberation. It is created when a sound wave is being reflected to the surfaces causing it to have a many reflection building up and decaying as these waves are being absorbed bu the surfaces in the area which could be tables, chairs, people or the air. Reverberation is the group of the reflected sounds in an enclosed area.

The current in the company's lightbulbs was too high. Why were the tests you ran relevant to the problem?

Katena32 [7]

The correct option is C.
In an electric circuit, resistance is defined as the friction in an electrical circuit which controls the flow of current. In an electric circuit, the resistance involved determined the amount of voltage that will be released; the higher the resistance the lower the voltage that will be released and the lower the resistance the higher the voltage that will be released. Thus, in a situation where the current released is too high, then the resistance has to be increased to lower the current.
