Good morning.
We calculate the acceleration with the <em>Torricelli equation</em>:

We see that:

Now:

Now we can calculate the
resultant force that makes that acceleration of
0.3 m/s² with the 2nd Law of Newton:

We have a force of
26 N → and a friction force
F ←. Adding those vectors, he have a force
6 N →. Therefore:
26 - F = 6
F = 20 NWe have a friction force of 20 N. We calculate the kinect coefficient with the formula:

Since we are in a horizontal plane, we hava that
N = P = mg = 200 NTherefore:
Answer:
B
Explanation
Has the greatest deflection of the light ray from the initial ray direction.
C= 5/9*(F - 32) so F=C*9/5 + 32
F= 25*9/5 +32 = 77 Fahrenheit
-It takes air from it's surroundings.
-Compresses the air
-Removes Nitrogen
-Delivers an electric Interface
-Then it delivers the purified oxygen
