Answer:
The repulsive force is
.
Step-by-step explanation:
Consider the provided information.
The coulomb's law to calculate the repulsive force: 
Where the value of k is 9.00×10⁹ Nm²/C²
Substitute the respective values in the above formula.
![F=\frac{9\times10^9\frac{N\cdot m^2}{c^2} \times(-24\times10^{-9}C)^2}{[(13 cm)(\frac{1m}{100cm} )]^2}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B9%5Ctimes10%5E9%5Cfrac%7BN%5Ccdot%20m%5E2%7D%7Bc%5E2%7D%20%5Ctimes%28-24%5Ctimes10%5E%7B-9%7DC%29%5E2%7D%7B%5B%2813%20cm%29%28%5Cfrac%7B1m%7D%7B100cm%7D%20%29%5D%5E2%7D)



Hence, the repulsive force is
.
ANSWER :
Watch that , for option 1 , 3 and 4 there is two values of Y for same X . That is not possible at all. Because How can a function gives you two different output as for same input ? So it is very Clear that Option 2 is a function and the other are not function. I have marked Which are function and which are not.
Answer:
Option B.
Step-by-step explanation:
From the given figure it clear that the the vertices of the polynomial are Q(2,0), R(4,5), S(8,7), T(6,4) and U(10,3).
Distance formula:
Using distance formula, we get
Now, the perimeter of the polynomial is
units.
Therefore, the correct option is B.
Answer:
If this is a parallelogram:
∠y = 112°
corners opposite the 112° corners = 68° [(360° - 112° - 112°)/2 = 68°]
∠z = 68° - 40° = 28°
∠x = ∠z = 28°
