Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left.  If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar.  We want to find the sum of the forces acting on the object.  In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

What is one characteristic of a rain forest?
Svetradugi [14.3K]
Different layers makes the most sense due to the fact it can’t be a dry climate because of the vegetation, also there is a lot of plants so minimal plants isn’t an option, and the temperature in a rain forest is usually very humid so cold temperatures can’t be an answer.

Consider the reaction H2SO4 + 2 NaOH -> Na2SO4 + 2H2O as it represents an acid-base tritration. The equivalence point occurs
sdas [7]
We consider the given reaction H2SO4 + 2 NaOH -> Na2SO4 + 2H2O as applies to an acid-base titration.
            moles NaOH = c · V = 0.2767 mmol/mL · 25.34 mL = 7.011578 mmol
            moles H2SO4 = 7.011578 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH
                                      = 3.505789 mmol
Hence
            [H2SO4]= n/V = 3.505789 mmol / 39.54 mL = 0.08866 M
The answer to this question is  [H2SO4] = 0.08866 M
