Identify two ways of changing the strength of an electric force

2 answers:

8 0

When you talk about "the strength of an electric force" in middle school, I'm pretty sure you're talking about the force between two electrostatic charges that either pulls them together or pushes them apart.

The strength of that force depends on

-- the product of the amounts of charges on the two charged objects

-- the distance between the centers of their charges.

An ocean wave has a speed of 36 m/s and a frequency of 3 Hz.<br> What is its wavelength?

dsp73

Answer:

f=4Hz

Explanation:

frequency of a wave if it has a wavelength of 3.0 m and a wave speed of 12m/s

v=fλ → f=v/λ

f=12/3

f=4Hz

A parallel-plate capacitor with circular plates of radius R is being discharged. The displacement current through a central circ

Dvinal [7]

Answer:

The discharging current is $I_d = 36.8 \ A$

Explanation:

From the question we are told that

The radius of each circular plates is R

The displacement current is $I = 9.2 \ A$

The radius of the central circular area is $\frac{R}{2}$

The discharging current is mathematically represented as

$I_d = \frac{A}{k} * I$

where A is the area of each plate which is mathematically represented as

$A = \pi R ^2$

and k is central circular area which is mathematically represented as

$k = \pi [\frac{R}{2} ]^2$

$I_d = \frac{\pi R^2 }{\pi * [ \frac{R}{2}]^2 } * I$

$I_d = \frac{\pi R^2 }{\pi * \frac{R^2}{4} } * I$

$I_d = 4 * I$

substituting values

$I_d = 4 * 9.2$

$I_d = 36.8 \ A$

A 10 kg package is delivered to your house. Use one complete sentence to describe an example of how work is done on the package

Mamont248 [21]

Answer:

Hey :)

Explanation:

Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mas of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.

hope this helps :) xo
