The force F between two charges Q1 and Q2 in a vacuum is proportional to the product of the charges and is inversely proportiona
dangina [55]

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.

What is the arc length of a circle that has a 6-inch radius and a central angle that is 65 degrees? Use 3. 14 for pi and round y
noname [10]
C=2πr

C=2π6

C=<span>37.6991118431
</span>
That's the arc length of the whole circle, i.e. the arc length of 360°.

65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.6991118431 is 
6.8067840827819444444444444444444.  Rounded to the nearest hundredth, the answer is 6.81 inches.

That's real pi, lets see if it makes a difference to use "stupid pi".

C=2πr

C=2π6

C=37.68

That's the arc length of the whole circle, i.e. the arc length of 360°.

65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.68 is 
6.803333333333333333333333.  Rounded to the nearest hundredth, the answer is 6.80 inches.
Yep makes a difference.  That's why you don't use stupid pi.  3.14159 is what we always used in engineering, or just the pi button and using a ton of digits.

Answer: 6.80 inches.
