1.000. An ellipse with an eccentricity of 0 is a circle.
<u>Answer:
</u>
C option is correct
20 movable and 20 fixed pulleys required
<u>Explanation:
</u>
To lift a 27,800 N elephant with a 700 N drive,
27800/700=39.7
the individual requires a mechanical favorable position of 39.7 which is equivalent to 40. A solitary movable pulley gives a mechanical favorable position of 2, two portable pulleys yield a mechanical preferred standpoint of 4, and a framework with three movable pulleys results in a mechanical favorable position of 6. In light of this example, 20 movable pulleys and 20 fixed are required to give a mechanical preferred standpoint of 40
