Frequency, f = 1/T,   Period  T = <span>4.85 * 10 ⁻² s</span>

f = 1/(4.85 * 10 ⁻²)

f ≈ 20.619 ≈ 20.6

The frequency is B. 20.6 Hertz

Here's an interesting factoid to remember:

                  (Period of any wave) x (Frequency of the wave)  =  1 .

If you can memorize that, then you'll always remember that

                       Period  =  1 / frequency
and
                 Frequency  =  1 / period .

The second one is what you need for this problem.

                 Frequency  =  1 / period

                                     =  1 / (4.85 x 10⁻² second)

                                     =  1 / (0.0485 second)

                                     =     20.62 / second

                                     =     20.62 Hz.    (rounded)

Which item is not considered electromagnetic energy?
suter [353]
Sound waves are known to be the one that's not considered as a type of electromagnetic energy. As for microwaves and x-rays, they tend to share the same frequencies that can be considered as electromagnetic, and sound waves have a different frequency than them.

Two objects separated by a distance r are each carrying a charge q The magnitude of the force exerted on the second object by th
Sindrei [870]

Answer:F=4F

Explanation: Columbs law states that The force between the two point charges is directly proportional to the product of charges and inversely proportional to the square of distance between them

Force between the two charges is given by

F=K*q1*q2/r^2

if one charge become 4 times, new force is,

F=4(K*q1*q2)/r^2

F=4F

Where q1 and q2 are the point charges

r is the distance between the two charges

K is a constant of proportion called electrostatic force

What happens when charged object is brought near uncharged object?<br> Attract or Repel ?
Makovka662 [10]
When a charged object is brought near to but does not touch a neutral object, it causes the side of the neutral object that the charged object is near to become the other charge. It causes charge migration within the neutral object so the two charges (positive and negative) move to opposite sides of the object. Because the two objects do not touch, they do not repel each other, but rather have a slight attraction because of charge migration. If the two object were to touch then they would repel.
