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.

Answer:

4500

Explanation:

hey there!

first we convert the khz to hz=30000hz

we use the formula 2d=distance×time

2d=1500×6

d=9000/2=4500

i think this is the right answer....

hope this helps u :)

Which stament best describes resistance

yaroslaw [1]

Answer:

Resistance is a measure of the opposition to the flow of current in an electrical circuit.

Explanation:

It is symbolized by the Greek letter omega (Ω), resistance is measured in ohms.

If an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm
