Answer:652.05 J
Explanation:
Given
Weight of lifter
vertical distance move
Work done in lifting the weight is equal change in Potential Energy of weight
Change in Potential Energy
therefore work done is equal to
Answer:
Explanation:
We have given number of turns N = 560
Inductance L = 8.9 mH
Current through the coil = 7 mA
Inductance of the coil is given as
Where N is number of turns I is current and is flux
So
