A force is said to have done work, if it manages to cause a displacement in an object from its starting point. Power can be defined as the rate of doing work. The work can be calculated using the following formula:
Work done ⇒ Force × Displacement
The power can be calculated using the following formula:
Power ⇒ Work ÷ Time
In order to calculate the work and power, the force and distance should be known. The force and distance will help calculate the work, which will help in the calculation of the power of the object.
Hence, the answer is 'you must known force and distance to calculate both'.
Work and power, concepts from physics, are similar in that both require knowledge of force and distance for their calculation.
Work and power are both concepts dealing with energy in physics. The correct statement that describes how work and power are similar is 'You must know force and distance to calculate both.' To calculate work, the formula is work = force x distance. For power, which is the rate at which work is done, the formula is power = work/time. Although time is included in the calculation for power, it's not required in the calculation for work. Thus, force and distance are the key common components needed for both calculations.

False
b. Experimental group
c. Hypothesis
d. Variable
The factor of interest in an experiment is called the Variable.
In an experiment, the factor of interest is called the Variable. The variable is the specific aspect or condition that is being tested or manipulated in an experiment to determine its effect on the outcome.
For example, if you are experimenting to test how different amounts of fertilizer affect plant growth, the variable would be the amount of fertilizer applied. In this case, the amount of fertilizer is the factor of interest that is being studied.
Therefore, the correct answer is d. Variable.
