Answer:

The correct answer is A

Explanation:

The question requires as well the attached image, so please see that below.

Coulomb's Law.

The electrical force can be understood by remembering Coulomb's Law, that describes the electrostatic force between two charged particles. If the particles have charges $q_1$ and $q_2$ , are separated by a distance r and are at rest relative to each other, then its electrostatic force magnitude on particle 1 due particle 2 is given by:

$|F|=k \cfrac{q_1 q_2}{r^2}$

Thus if we decrease the distance by half we have

$r_1 =\cfrac r2$

So we get

$|F|=k \cfrac{q_1 q_2}{r_1^2}$

Replacing we get

$|F|=k \cfrac{q_1 q_2}{(r/2)^2}\\|F|=k \cfrac{q_1 q_2}{r^2/4}$

We can then multiply both numerator and denominator by 4 to get

$|F|=k \cfrac{4q_1 q_2}{r^2}$

So we have

$|F|=4 \left(k \cfrac{q_1 q_2}{r^2}\right)$

Thus if we decrease the distance by half we get four times the force.

Then we can replace the second condition

$q_{2new} =2q_2$

So we get

$|F|=k \cfrac{q_1 q_{2new}}{r_1^2}$

which give us

$|F|=k \cfrac{q_1 2q_2}{r_1^2}\\|F|=2\left(k \cfrac{q_1 q_2}{r_1^2}\right)$

Thus doubling one of the charges doubles the force.

So the answer is A.

In a random sample of 200 students from Northern State University, 150 said that they own an Therefore, probably at least 50% of

kirza4 [7]

Answer:

No fallacy

Explanation:

The statement that at least 50% of the students at Northern State own an iPod is best categorized as no fallacy.

This statement is very true and consistent with the facts presented in the passage.

A fallacy is a mistaken belief usually based on biased arguments.

Total number of students sampled = 200

Number of iPod owners = 150

Percentage of iPod owners = $\frac{number of iPod owners}{Number of sample}$ x 100

Percentage of iPod owners = $\frac{150}{200}$ x 100 = 75%

We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.
