A well designed product will increase in sells and in stock.
It may be an engine cooler, or it may be for the boats speed
But I think it is for cooling the engine down
Answer:
B. 26 rpm
Explanation:
The sprocket has a diameter of 10 in
The back wheel has a diameter of 6.5 in
One complete revolution formula is : 2πr -------where r is radius
For the sprocket , one revolution = π * D where D=2r
π * 10 = 31.4 in
For the back wheel, one revolution = π* 6.5 = 20.42 in
The pedaling rate is : 40 rpm
Finding the ratio of revolutions between the sprocket and the back tire.
In one revolution; the sprocket covers 31.4 in while the back tire covers 20.42 in so the ratio is;
20.42/ 31.4 = 0.65
So if the speed in the sprocket is 40 rpm then that in the back tire will be;
40 * 0.65 = 26 rpm
Answer: C. There is no relationship
Explanation:
At the various temperatures, the flow rates do not seem to show any relation as similar temperatures can yield different flow rates.
The flow rates neither appear to generally increase nor decrease as a result of a decrease or an increase in temperature which means that there is a lack of a positive, negative and curvilinear relationship.
There is simply no relationship.
