"I want to run, to skip, and to jump" is an example of _____.
NNADVOKAT [17]
<span>The question is asking us to define the sentence ""I want to run, to skip, and to jump". This is a parallel construction, which means that the three parts ("to run", "to skip" and "to jump" are in the same kind of construction - to <verb>. It could be considered comma splice, but a comma splice would rather be the case if there were different subjects : for example in "I want to run, she wants to skip". </span>

"• Diffusion - coffee and bacon particles are floating around
• They do not interact/blend with each other
• Because of fluidity, the particles are gliding past each other and filling the open space within the nose."

Rank the vector combinations on the basis of their magnitude.
melomori [17]

I think this is about the 5th or 6th time I've seen this question
submitted to Brainly.  So far, nobody has yet given us any of
the rest of the question ... the part that tells us something about
the vectors, so that we have some way to know their magnitudes.
So far, nada.

the impact time for a particular collision is 3.0 × 10-3 seconds and the impulse in the collision is 0.30 newton seconds. what i
Zanzabum
There are several information's already given in the question. The answer can be easily deduced using those information's. 

Time = 3.0 * 10-3 seconds
Impulse = 0.30 newton
Then
Force = Impulse/Time
          = 0.30/3.0 * 10-3
          = 1 * 10^3 newtons.
I hope the above procedure is clear for you to understand and it has actually come to your great help.

gregori [183]

Answer:

I would need more electrons    1.3125 10¹⁰ electrons

Explanation:

Static electricity is formed by induced charges in each part of the system, so the net charge does not change.

 

Let us analyze the situation presented, if the carpet acquires a positive charge, so that it does not alter the total charge in man, it should acquire a negative charge, to have a net negative charge I would need more electrons that have a negative charge.

We can know the number of electrons by a rule of proportions, if an electron has a charge of 1.6 10-19 C for a charge of 2.15 10-9 C how many electrons are needed

      # = 2.15 10⁻⁹ /1.6 10⁻¹⁹

      # = 1.3125 10¹⁰ electrons

The number is very high for which we will not worry about rounding since the number of electrons must be an integer
