The distance between the charges is 13.86 X 10⁴m
<u>Explanation:</u>
Given:
Force, F = 1.2N
Charge, q₁ = 1.602 X 10⁻¹⁹ C
k = 8.987 X 10⁹ Nm²/C²
Distance, d = ?
According to Coulomb's law:

Substituting the value in the formula we get:

Therefore, the distance between the charges is 13.86 X 10⁴m
Answer:
Clockwise and counter clockwises, depands.
Explanation:
The direction of current in a loop of wire in a magnatic field depands on the direction in which the loop is moved and the applied magnatic field.
this is determined by what is called right hand rule.
I will give one scenario, let's say that the loop is moved upwards and the applied magnatic field is into the page (if you drew the loop in 2D on a piece of paper), in this case the direction would be clockwise.
Answer:
0.028 M.
Explanation:
NOTE: This question is a chemistry question. However, the answer to the question can be obtained as shown below:
We'll begin by calculating the number of mole in 2.52 g of oxalic acid, C₂H₂O₄. This can be obtained as follow:
Mass of C₂H₂O₄ = 2.52 g
Molar mass of C₂H₂O₄ = (2×12) + (2×1) + (4×16)
= 24 + 2 + 64
= 90 g/mol
Mole of C₂H₂O₄ =?
Mole = mass / molar mass
Mole of C₂H₂O₄ = 2.52 / 90
Mole of C₂H₂O₄ = 0.028 mole
Finally, we shall determine the molarity of the solution. This can be obtained as follow:
Mole of C₂H₂O₄ = 0.028 mole
Volume = 1 L
Molarity =?
Molarity = mole / Volume
Molarity = 0.028 / 1
Molarity = 0.028 M
Therefore, the molarity of the solution is 0.028 M.
