Aforce of 13 n is applied to the handle of a screwdriver being used to pry off the lid of a
paint can. as the input force moves through a distance of 0.25 m, the screwdriver does 2
j of work on the lid. what is the efficiency of the screwdriver? show your work.

Efficiency = 61.54%

Efficiency is given by the Formula;

Efficiency = work output/work input × 100%

Work input = Input force × distance moved by the input force

                  = 13 N × 0,25

                  =  3.25 Joules

Work output or work done by the screwdriver is 2 Joules

Therefore;

Efficiency = 2/3.25 ×100%

                =  61.54%

the electromagnetic energy from the sun arrives in the form of visible and invisible light.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
