Answer: OLEDs

Explanation:

The nanotechnology uses the surface of the carbon materials to generate the electricity. The evaporation of water on the surface of carbon materials helps in generation of electrical energy due to generation of thermal energy.

OLEDs can be defined as solid-state devices that comprises of organic molecules like carbon that will create electricity by exposing a surface for generation of thermal energy.

An attractive force of |1N| exists between two charged particles. The magnitude of both charges is the same. If the particles ar

Sever21 [200]

Answer:

A: -2.6 × 10^(-6) C and 2.6 × 10^(-6) C

Explanation:

According to coulombs law, the formula for the force between 2 charged particles is;

F = kq1•q2/r²

Where;

F is Force = |1N|

q1 and q2 are the charges of both particles

k is coulombs constant = 9 × 10^(9) N.m²/C²

r is distance between particles = 0.25

Now, the force |1N| means -1 or +1

Thus;

-1 = 9 × 10^(9) × q1•q2/(0.25)²

1 = 9 × 10^(9) × q1•q2/(0.25)²

Thus;

q1•q2 = -6.94 × 10^(-12)

Or q1•q2 = 6.94 × 10^(-12)

Now, we are told that the magnitude of both charges are the same.

Thus;

q² = 6.94 × 10^(-12)

q = √(6.94 × 10^(-12))

q = 2.6 × 10^(-6) C

Since from earlier, we saw that;

q1•q2 = -6.94 × 10^(-12)

Or q1•q2 = 6.94 × 10^(-12)

Thus means that one of the charges will be negative while the other will be positive.

Thus, the charges are;

-2.6 × 10^(-6) C and 2.6 × 10^(-6) C
