Answer:
Tech A
Explanation:
The amount of energy required to apply the same force with a 1:1 ratio is divided into 4, so you can apply 4 times as much force than a 1:1 ratio. efficiency and speed come into play here, but assuming the machine powering the gear can run at a unlimited RPM, 4:1 will have more force and a slower output speed than a 2:1 ratio.
Answer:
80grit
Explanation:
80 grit is coarsest grit that may be used on aluminum
The lowest grit sizes range from 40 to 60. From the given options 80 grit is practically available grit.
What is a sandpaper used for?
They are essentially used for surface preparation. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, either to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).
The number of tubs that each of them sold is; 24 tubs each
The number of days it will take for both of them to sell same amount of tubs is; 4 days
Number of cookies that Nicole had already sold = 4 tubs
Number of cookies sold by Josie before counting = 0 cookies
Nicole now sells 5 tubs per day and
Josie now sells 6 tubs per day.
Let the number of days it will take for them to have sold the same amount of cookies be d.
Thus;
5d + 4 = 6d + 0
6d - 5d = 4
d = 4 days
Thus, total number of cookies for both are;
Total for Nicole = 4 + 5(4) = 24 cookies
Total for Josie = 6(4) = 24 cookies
