Answer:
Where is question 12, we need it to answer this question
Explanation:
Answer:
The correct option is option (B)
Explanation:
Given that,
The equation below show the total amount of water in gallons, y that has flowed through two different types of showers heads after x minute.
Type A: y =1.25 x
Type B: y= 2.50 x
So,
The amount of water per minute is 
For type A
y =1.25 x

For type B
y =2.50 x


The amount of water flowed through Type B is twice that flowed trough type A per minute.
1). Work = (force) x (distance)
Work = (3,000 newtons) x (35 meters) = 105,000 newton-meters = <em>105,000 joules</em>
2). Power = (work) / (time)
Power = (105,000 joules) / (90 seconds)
= 1,166-2/3 joules per second =<em> 1,166 and 2/3 watts</em> .
<em>Note:</em>
That's no ordinary man.
1,166 watts is the same as roughly 1.6 horsepower.
Not too many people can sustain 1 horsepower or more for 90 seconds.
