Answer:

F=7.96*10^{-11}N

Explanation:

According to Coulomb's law, the magnitude of the electric force between two equals charges (q) is given by:

F=\frac{kq^2}{d^2}

Here k is the coulomb constant and d is the distance between the charges. For two electrons we have:

F=\frac{ke^2}{d^2}\\F=\frac{8.99*10^{9}\frac{N\cdot m^2}{C^2}(-1.6*10^{-19}C)^2}{(1.7*10^{-9}m)^2}\\F=7.96*10^{-11}N

select the correct scientific notation form of this numeral 541 5 * 10^2 5.4 * 10^2 5.4 * 10^2 5.0 * 10^2
USPshnik [31]
To find the scientific notation, you need to divide at the decimal by the power of 10. So since there are 2 powers of 10, what you want to do is move the decimal 2 places to the left which will give you: .054

Which of the following materials offer the least electrical resistance? Pure water, wood, salt water, glass
Vanyuwa [196]

Salt water offers the least electrical resistance.

<u>Explanation:</u>

Least electrical resistance indicates that any material which readily allows the electric current through itself, and shows more conductivity.

Here pure water doesn't contain any ions, so it is a bad conductor.

Wood and glass are also bad conductors of electricity.

Salt water contains ions, which conducts electricity which means it shows least electrical resistance.

What are the 3 laws of Newton
daser333 [38]

Answer:

What are Newton's 1st 2nd and 3rd laws of motion?

They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist.
