Answer:
C. 8.0
Step-by-step explanation:
The mechanical advantage is got from dividing the circumference of the shaft by the pitch of the screw.
Therefore, the circumference= 2πr
=2×π×2.3mm
=14.45mm
Mechanical advantage=14.45mm/1.8mm
=8.03
Answer:
162
Step-by-step explanation:
20736 x 729 x 4/216 x 64 x27
Now go ahead and do the cancellations
20736/216 =96
729/27 =27
64/4 =16
so you end up getting 96 x 27 x1 /26
96/16 =6
so you get 27 x 6 =162
Answer:
Feather, fork, baseball, desk, cow, tow truck, house, Earth, Sun
Step-by-step explanation:
The bigger the object, the more inertia it has, since it's harder to move a bigger object. So, since a feather is the smallest thing with the least amount mass, it should be the easiest to move, giving it the least amount of inertia. It's the opposite for the Sun, since it's the biggest object on the list.
I believe its the secound to last one
