<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

Answer:
20
27
Explanation:
Given parameters:
Atomic mass = 47
Atomic number = 20
Unknown:
Number of protons = ?
Number of neutrons = ?
Solution:
To solve this problem,
Atomic mass = number of protons + number of neutrons
Atomic number = number of protons
So;
Number of protons = 20
Now;
Number of neutrons = Atomic mass - number of protons
Number of neutrons = 47 - 20 = 27
