The attractive electric force between point charges q and -2q has a magnitude of 2.2 N when the separation

swat32

Answer:

The Magnitude of charge = q = 15.47 micro coulomb

Step-by-step explanation:

The attractive force between two points q and - 2 q = F = 2.2 Newton

The separation between two charges = 1.4 meters

Now from Coulomb's law = F = $(k \frac{q1 q2}{r^{2}})$ where k= $9 \times 10^{9}$ $\frac{N m^{2}}{c^{2}}$

So , 2.2 = $9 \times 10^{9}$ ( $(\frac{(q) ( - 2q)}{1.4^{2}})$

So , q ² = ( $\frac{0.479 \times 10^{-9}}{-2}$ )

For charge magnitude

I.e q ² = $2.395 \times 10^{-10}$

so, q = $1.547 \times 10^{-5}$

q = 15.47 \times 10^{-6} c

Or, q = 15.47 micro coulomb

Hence the Magnitude of charge = q = 15.47 micro coulomb Answer

Thank you so much!!!

Answer:

$\fbox{\begin{minipage}{16em}Option D: y = (4/7)x + 8 is correct\end{minipage}}$

Step-by-step explanation:

(1) A typical form of equation of a line is:

$y = Mx + b$

with, $M$ is slope and $b$ is y-intercept.

(2) Another straight line has equation in form of:

$y = Nx + c$

with $N$ is slope and $c$ is y-intercept

(3) If these two lines are perpendicular, according to the property of two perpendicular lines on the two-dimensional plane, we have:

$M$ x $N$ = -1

(4) Transform the given equation of original line into typical form:

$7x + 4y = -24\\$

<=> $4y = -7x - 24$

<=> $y = (\frac{-7}{4})x - \frac{24}{4}$

<=> $y = (\frac{-7}{4})x - 6$

=> $M = \frac{-7}{4}$

=> $N = \frac{-1}{M} = \frac{-1}{\frac{-7}{4} } = \frac{-4}{-7} = \frac{4}{7}$

=> Option D: $y = (\frac{4}{7})x + 8$ is correct (Slope = $\frac{4}{7}$ )

Hope this helps!

Answer:

Area:

$36\pi - 72 \: cm {}^{2}$

Step-by-step explanation:

$( \frac{1}{4} \times \pi \times 12 {}^{2} ) - ( \frac{1}{2} \times 12 \times 12) = 36\pi - 72$

Area of the blue area:

$36\pi - 72 \: cm {}^{2}$

Perimeter of blue area:unsure as no numbers are given for the slanted side if the triangle.
