Answer:
option 1 and option 2
Explanation:
option 1 and option 2
1)Take up the box: force is upwards, displacement is upwards as well, so good work as force & displacement are in the same direction
2) Accelerating:: because the individual is moving, force is positive, displacement is also in the same direction, so the work is positive.
3) carrying box at fixed speed :: as speed remain constant , force = 0 , therefore work =0
4) Decelerating to stop :: force is -ve because it is moving to finally stop, thus negative work
5) Lowering of the box :: force acts up direction , displacement is down , hence -ve work

Answer:
67%
Explanation:
Money supply = Money multiplier * Deposit worth
3 = Money multiplier * 2
Money multiplier = 3/2
Money multiplier = 1.5
Now, Money multiplier = 1 / Reserve ratio
1.5 = 1 / Reserve ratio
Reserve ratio = 1/1.5
Reserve ratio = 0.6667
Reserve ratio = 67%
So, the percent of deposits the banks hold as reserves is 67%
