they expand 10,300 joules of energy to lift some bricks with the lever . if 6,283 joules of energy are applied to bricks what is the lever effiency and why please show steps
0.61 %
61%
164%
I know that it is 61 % percent but why

The lever efficiency is calculated by dividing the amount of energy applied to the bricks (6,283 joules) by the total amount of energy expended (10,300 joules). This gives us a result of 61%. This means that 61% of the energy expended was used to lift the bricks, while the remaining 39% was lost to friction and other factors.
