Answer:

81/16 = 5 1/16

Step-by-step explanation:

-4(square root of x) -3 = -12

Add 3 to both sides

-4(square root of x) = -12 +3 = -9

Divide both sides by -4

(square root of x) = -9/-4

-/- equals +

(square root of x) = 9/4

Square both sides to cancel the square root

x = (9/4)^2 = 81/16 = 5 1/16

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

Express the exponential number 2.25 x 10-4 as an ordinary number. 22,500 0.000 022 5 225,000 0.000 225 none of the above

Evgesh-ka [11]

For this case we have the following number:
2.25 x 10-4
We observe that it is written in exponential notation.
The exponent is negative, therefore, we must move the point to the left.
We have then:
2.25 x 10-4 = 0.000225
Answer:
0.000225

P Is inversely proportional to v When p=5, v=8 Find a formula for p in terms of v

Tju [1.3M]

Answer:

p = $\frac{40}{v}$

Step-by-step explanation:

Since p is inversely proportional to v then the equation relating them is

p = $\frac{k}{v}$ ← k is the constant of variation

to find k use the condition when p = 5, v = 8

k = pv = 5 × 8 = 40, hence

p = $\frac{40}{v}$
