Answer:

<h2>This represent a chemical reaction.</h2>

Explanation:

What Theresa saw is a chemical reactions due to the interaction between the two colors. There are several actions that constitutes evidence of chemical reactions: change in color, formation of bubbles, formation of smoke, the formation of a precipitate and a clear liquid becoming cloudy, all these effects are signs of a chemical reaction.

In this case, Theresa created an experiment where two substances are changing color from red to blue, this is a sing of a chemical reaction, that's the answer.

It takes 20s for 3x10^6 electrons to flow through a wire ,what is the current?

Elina [12.6K]

Answer:

Explanation:

The variables we know and are given are:

time, t = 20s

Charge, Q = 3x1-^-6 electrons, which is just 3x10^-6C (C stands for Coulombs, which is the unit for Charge)

We need to find the current, I, and since we know Q and t we can substitute these values into the given equation:

I=Q/t (which if you look at what the RHS is saying, its Charge over time, or more literally means the amount of charge passing a point over a period of time)

If we substitute these values, we will get I as:

I = Q / t

I = 3x10^-6 / 20

I = 1.5x10^-7 A

Hope this helps!

When driving at night, only use your high-beam headlights___

zzz [600]

Answer:

Explanation:

While answer C may sound correct, Answer B is makes more sense. We know you cant use High-beam lights when u cant see ongoing traffic because it could affect the other driver coming across from you. Its good to use it when legal and safe, but in that term I still don't believe there's no reason for HIGH-beamed. That's this leaves B, when you are on u lighted streets.
