Answer:
Workdone W = 1465.1 J
Explanation:
The weight of the water = density × volume
weight of the water = 1000 kg/m³ × 100 cm³
weight of the water = 1000 kg/m³ × 0.0001 m³
weight of the water = 0.1 kg
weight of the bucket = 5 kg
weight of the rope = 
= 
Leakage = 
= 
Total weight = 
= 
Force = wg
Force = ()g
Force = 9.8 ()
Finally; the amount of work spent in lifting the bucket, rope, and water is calculated as follows:
Voltage =Current * Resistance
= 9 * 43
Voltage = 387 V
Answer:
A 10 N force pointing up
Explanation:
If the net acceleration of the object is horizontal pointing to the right, that means that all vertical forces must have canceled out, and the only ones "unbalanced" are the horizontal ones (10 N to the right minus 5 N to the left giving a net force of 5 N to the right).
Since they mentioned only one vertical force pointing down (10 N), there must be another one of same magnitude but pointing in opposite direction (up).
Then there must also be a 10 N force pointing up acting on the object.
