Answer:
The last option

Explanation:
Let's take this step by step.
First, we are looking for two moles of NO₂
This means that we can exclude the first two options since each of them shows only one mole.

Now, the compound we are looking for is NO₂. This means that it has two oxygen moles and one nitrogen mole.
You have stated that nitrogen is the blue one. Therefore, the compound we are looking for will be the one having one blue ball (representing nitrogen) and two red balls (representing oxygen).

Now taking a look at the choices, we will find that the last one fits our criteria.
1- It has two moles
2- each mole as two red balls and one blue ball

Therefore, the last option is the correct one

Hope this helps :)

The electric force is exerted by a 40-nC charged particle located at the origin of a Cartesian coordinate system on a 10-nC char
notsponge [240]

Answer:

450 × 10 ⁻⁹ N

Explanation:

From the given:

The direction of force is;

tan \ \theta = \dfrac{2}{2}

\theta =tan  ^{-1} (1)

\theta = 45^0

Hence, the angle is 45° counterclockwise from + x-axis

However;

the magnitude of the force is:

F = \dfrac{kq_1q_2}{r^2}

F = \dfrac{(9*10^9 \ Nm^2/C^2 )*( 40 * 10^{-9} \ C ) * (10*10^{-9} \ C)}{(\sqrt{8})^2}

F = 450 \times 10^{-9} \ N
