A green plant has Chemical energy.
This chemical energy is stored as Chlorophyll which in turn reacts with sunlight and water, to form sugar through the process of Photosynthesis.
Power is the rate work done given by dividing work done by unit time. It is measured in watts equivalent to J/s.
In this case the force by the student is mg = 490 N (taking g as 9.8m/s²)
Work done is given by force × distance,
Therefore, Power =(force × distance)/ time, but velocity/speed =distance/time
Thus, Power = force × speed/velocity
= 490 N × 1.25
= 612.5 J/S (Watts)
Hence, power will be 612.5 Watts.
Answer:
The independent variable is plotted on the x-axis. This is the variable that is being manipulated or controlled.
