The input work = Force x distance
So I/P = 45 x 1.5 = 67.5 N.m
The output work = Force x distance
So, O/P = 87.6 x 0.4 = 35.04 N.m
Efficiency = (output work / Inputwork) x 100
= ( 35.04/67.5) x100
Efficiency = 51.91 %
Answer:
None.
Explanation:
The weight of the astronaut is equal to the force of gravity the astronaut feels that depends on the mass of the planet.
Because the mass of the Earth is different than that of Jupiter, Saturn and Mars, the astronaut's weight will change when he/she travels to either planets.

The correct answer is:
<span>C. as a p-type semiconductor with the pegs representing electrons and the holes representing positive charges
</span>
The pegs represent the electrons and the holes represent the positive charges: when a peg is moved, it can be seen as an electron moving, and this peg (the electron) occupies a new hole (so, it recombines with the hole) leaving behind a free hole.
Moreover, a<span> p-type semiconductor has a larger concentration of holes than electrons, and the same is true for the puzzle (we have in fact 18 pairs of pegs-holes (electrons-holes), and then we have 2 free holes, so the concentration of holes is larger). </span>
