List two reasons for why a non-physicist might be interested in electrostatic interactions.
-Dominant- [34]

Answer:

all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics

Explanation:

Electrostatic interactions, have many rare manifestations in nature, which causes many reasons to study them.

- Lightning is a very striking form of electricity

- The biological processes are governed by currents of inanes and potential differences

- The transfer of nutrients and fertilizers to plants is with ion exchange, electrostatic forces

- all modern electronics is based on electricity

- the electric charge in very dry places, creates high currents that can create fires or kill people

In summary all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics

The force of attraction that a -40.0 μC point charge exerts on a +108 μC point charge has magnitude 4.00 N. How far apart are th
Karolina [17]

Answer:

F = k q1 q2 / r^2

r^2 = k q1 q2 / F  = 9E9 * 4E-5 * 10.8E-5 / 4

r^2 = 9 * 4 * 10.8 / 4 * E-1 = 9.72 m^2

r = 3.12 m

Calculate the peak voltage of a mains supply of 240Vrms.​
pashok25 [27]
Answer:

So 240V RMS is equivalent to 339 V peak, or 679 V peak to peak and can be written as 240 Vrms. (the formula is Vrms = Vmax / √2). The waveform is a sinusoid varying about a neutral, which can also be drawn as a vector with a single arrow pointing away from neutral.

What is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?
goldenfox [79]

Well, "speed" normally = (total distance covered) / (time to cover the distance).

In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".

Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...

Speed of visits = (total houses visited) / (time to visit them).

Speed of visits = (800 million houses) / (48 hours)

Speed of visits = 16.67 million houses per hour.

That's 277.8 thousand houses per minute

That's <em>4,630 houses per second</em>
