What is the equation for calculating the electrical force, Fe, between two charges? Fe = kStartfraction q Subscript 1 baseline t

imes q Subscript 2 baseline over d Endfraction. Fe = Startfraction q Subscript 1 baseline times q Subscript 2 baseline over d Superscript 2 baseline Endfraction. Fe = kStartfraction q Subscript 1 baseline times q Subscript 2 baseline over d Superscript 2 baseline Endfraction. Fe = kStartfraction q Subscript 1 baseline times q Subscript 2 baseline over d Endfraction Superscript 2 baseline.

Answer:

F=\frac{K Q1Q2}{d^2} \\

Step-by-step explanation:

According to coulombs law "the force of attraction or repulsion between two charges Q1 and Q2 in a given medium is directly proportional to the product of their charges and inversely proportional to the square of the distance separating them"

F=\frac{K Q1Q2}{d^2} \\

where

k = constant of proportionality (9.05*10^9)

Grace [21]

Answer:

No, there is not a significant difference

Step-by-step explanation:

The sample mean (1.3) is less than the sample standard deviation (1.9). The sample mean would have to be greater than 1.9 for there to be a significant difference

Nicolet wants to buy a new state of the art computer for R35 000. She decides to save by depositing an amount of R500 once a mon
sineoko [7]

Answer:

54.72 months

Step-by-step explanation:

Given:

Future value = R35,000

Annuity = R500

Interest = 11.32% per year

Interest per month, r = \frac{11.32}{12} = 0.943% = 0.00943

Let 'n' be the total time in months taken

Now,

Future value of annuity is calculated using the formula as:

\textup{Future value}=\textup{Annuity}\times[\frac{(1+r)^n-1}{r}]

on substituting the respective values, we get

35000=500\times[\frac{(1+0.00943)^n-1}{0.00943}]

or

70=[\frac{(1.00943)^n-1}{0.00943}]

or

1.6601 = 1.00943ⁿ

taking log both sides, we get

log(1.6601) = n × log(1.00943)

or

0.22= n × 0.00402

or

n = 54.72  months

matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that beca
Vesna [10]

Answer:

Matt is correct

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are the same

In this problem we can have two cases

case 1) The two equations are equal, in this case the system has infinite solutions

case 2) The two equations have the same slope but different y-intercept, in that case the system has no solution.

therefore

Matt is correct

katen-ka-za [31]

Answer:

7 - 3\sqrt{3}

Step-by-step explanation:

Given

3 + \sqrt{x+7} - \sqrt{3x} ← substitute x = 9

= 3 + \sqrt{16} - \sqrt{27}

= 3 + 4 - \sqrt{9(3)}

= 7 - 3\sqrt{3}
