100% of this force does work on the object. which one? a.) arrow bb.) arrow c c.) arrow a

Arrow C

Step-by-step explanation:

As we can see that when we apply at arrow A the force is downward while the force acting by the board is upward which cancels the effect so no work will be done

Now about the Arrow B when we apply a force on it then a force will act and body will move so work will be done

we knot that

Work done = Force . Displacement

Work = Fd cos Ф

Here in B it will not be maximum because there will be an angle acting on it which is greater then 0 so it will not maximum

while in case of arrow C the angle between force and displacement is 0

as cos(0)=1

so work done = Fd which is the maximum value

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
