Examine the scenarios. Scenario W: A force of 75 N moves a box 15 m. Scenario X: A force of 100 N moves a box 12 m. Scenario Y: A force of 50 N moves a box 20 m. Scenario Z: A force of 25 N moves a box 45 m. In which scenarios is the same amount of work done on the box? W and X
W and Z
X and Y
Y and Z

B) W and Z

Explanation:

To calculate work use the formula: W = Fd (Work = Force x displacement)

Scenario W: A force of 75 N moves a box 15 m. --> 1125 J

Scenario X: A force of 100 N moves a box 12 m. --> 1200 J

Scenario Y: A force of 50 N moves a box 20 m. --> 1000 J

Scenario Z: A force of 25 N moves a box 45 m. --> 1125 J

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
