Answer:

<h3>The given statement "The force F between two charges Q_1 and Q_2 in a vacuum is proportional to the product of the charges and is inversely proportional to the square of the distance between two charges" is a <u>Coulomb's law.</u></h3>

Step-by-step explanation:

Given that "The force F between two charges Q_1 and Q_2 in a vacuum is proportional to the product of the charges and is inversely proportional to the square of the distance between two charges"

<h3>The given statement is a <u>Coulomb's law.</u></h3>

Coulomb's law states that the magnitude of the electrostatic force F of attraction or repulsion between the two point charges Q_1 and Q_2 is directly proportional to the product of the magnitudes of charges Q_1 and Q_2  and it is inversely proportional to the square of the distance between the two charges.

In a game the player wins if he rolls a 6 on a number cube. If the number cube is rolled 18 times, then what is a reasonable pre
monitta

Answer:

15/18

Step-by-step explanation:

A single di has 6 sides, meaning the probability of rolling a 6 is 1/6. So if you roll a di 18 times you would probably get 6 three times. Meaning the number of unsuccesful rolls would be (18/18 - 3/18). Hope this helps.

If the diagonal of a square is approximately 12.73, what is the length of its sides?
Alja [10]

Answer:

The length of the sides of the square is 9.0015

Step-by-step explanation:

Given

The diagonal of a square = 12.73

Required

The length of its side

Let the length and the diagonal of the square be represented by L and D, respectively.

So that

D = 12.73

The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

D^{2} = L^{2} + L^{2}

Solving further, we have

D^{2} = 2L^{2}

Divide both sides by 2

\frac{D^{2}}{2} = \frac{2L^{2}}{2}

\frac{D^{2}}{2} = L^2

Take Square root of both sides

\sqrt{\frac{D^{2}}{2}} = \sqrt{L^2}

\sqrt{\frac{D^{2}}{2}} = L

Reorder

L = \sqrt{\frac{D^{2}}{2}}

Now, the value of L can be calculated by substituting 12.73 for D

L = \sqrt{\frac{12.73^{2}}{2}}

L = \sqrt{\frac{162.0529}{2}}

L = \sqrt{{81.02645}

L = 9.001469325

L = 9.0015 (Approximated)

Hence, the length of the sides of the square is approximately 9.0015
