Explanation:
Mass of boy = 40 kg
Mass of box = 20 kg
Total mass = 60 kg
Initial potential energy = 0 (since height would be 0 initially)
Final potential energy = mgh
Taking g as 10 m/s²,
=> 60 × 10 × 15
= 9,000 J
So, work done = final potential energy - initial potential energy
= 9,000 J
Power = Work/Time
=> Power = 9000/25
=> Power = 360 J/s
or 360 watt.
Answer:
The equal number of books that is arranged on 16 empty shelves is 36 .
Step-by-step explanation:
Given as :
The total number of books Miguel need to arrange = 576
The total number of empty shelves = 16
Let The total number of books arrange on each shelves = x
So , According to question
The total number of books Miguel need to arrange = The total number of empty shelves × The total number of books arrange on each shelves
I.e 576 = 16 × x
Or, x = 
∴ x = 36
Hence The equal number of books that is arranged on 16 empty shelves is 36 . Answer
