Answer:
Neither end of Earth’s axis is tilted toward or away from the sun.
Answer:
The efficiency is just 0.016
Explanation:
The efficiency is given by the useful energy ÷ by the total energy.
1 W is the same that 1 joule per second
If you do the math:
1.6/100=0.016
Answer:
<em>Velocity</em><em> </em><em>-</em><em>time</em><em> </em><em>graph</em><em> </em>
Explanation:

1) Resultant force:
The two forces have same magnitude (4 N) but opposite verse, so their resultant is zero:
2) Couple
The two forces have opposite direction and they are applied at a distance d=0.2 m from the center of the square, so they generate a couple equal to the sum of the torques generated by each force:
Answer:
Fn = 246.2 N
Explanation:
I assume you meant meters per second squared for acceleration of the elevator. All you have to after your picture/free-body diagram is made is add the forces together. You could do this by finding them separately like I did or use Fn = m(Fg + Fe). I just calculated magnitude and didn't worry about signs.
