Answer: 0.17hp
Explanation:
Power output = power input × 85%
Power output = power input × 0.85
Power input = IV/0.85
Power input = 9×12/0.85
Power input = 108/0.85
= 127.058 watts
Converting to horse power = 127.058W × 1horse power/745.7W
= 127.058 × 0.001341
= 0.17hp
Answer:
The wavelength of the water is 
Explanation:
From the question awe are told that
The distance between the two boats are 46 m
Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as
Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)
= 4.5
Now the wavelength of the water is 

Answer:
i DONT KNOW

why? because i dont knowXD
<span>When picking up a load, the correct fork spacing must be spaced in an evenly manner in which the centre stringer of the pallet and the balance of the load should be spaced evenly in which makes the picking up the load to be correct and well-balanced.</span>
The correct answer is A. Holding a heavy book.
In this case, there is not a displacement of the system and you must remember that work is force times displacement.
