If two metal balls each have a charge of -10^-6 C and the repulsive force between them is 1 N, how far apart are they? (Coulomb'
Vitek1552 [10]

Answer:

The distance between the charges is 9.5 cm

(c) is correct option

Explanation:

Given that,

Charge q= 10^{-6}\ C

Force F = 1 N

We need to calculate the distance between the charges

Using Coulomb's formula

F = \dfrac{kq_{1}q_{2}}{r^2}

Where, q = charge

r = distance

F = force

Put the value into the formula

1=\dfrac{9.0\times10^{9}\times(-10^{-6})^2}{r^2}

r=\sqrt{9\times10^{9}\times(-10^{-6})^2}

r=0.095\ m

r= 9.5\ cm

Hence, The distance between the charges is 9.5 cm

The less mass an object has, the --- its gravitational f
BaLLatris [955]

Answer:

<em>The less mass an object has, the </em><u>less</u><em> its gravitational  [force.]</em>

Explanation:

Newton's Law of Gravity states that F_G=\frac{Gm_1m_2}{r^{2}}. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em> F_G. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em> F_G!

I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?

Which energy does the water flow into the river?
kupik [55]
The water in a reservoir behind a hydropower dam is another example of potential energy. The stored energy in the reservoir is converted into kinetic energy (motion) as the water flows down a large pipe called a penstock and spins a turbine.
