Answer:
72 km
Explanation:
We are given that
John marker reads=239 km
John travels and reaches the marker=149 km
John retraces his path and reaches the marker=167 km
We have to find the John's resultant displacement from 239 km.
Displacement:The displacement is the distance between two positions.
By definition of displacement
John's resultant displacement from 239 km=239-167
John's resultant displacement from 239 km=72 km
Hence, John's resultant displacement from 239 km=72 km
Work formula is Work=N∙M or Joule (J)
So you have the following given:
50 000 is the output work
.8 is the efficiency
if you input the given = 50000 = .8*J
To get the answer just divide 50000 by .8 to get the answer.
62,500 J is the amount of work to be done.
Answer:

Answer/ Explanation
the loop has no force and the wires cancel each other but the wire on the loop has a force
The segment a get the same force for both but in the loop segment b get an opposite force so the net force on the loop is smaller
The loop wire has forces that all cancel out while the other straight wire doesn't.
