Answer:
![F=1.26*10^{-3}N](https://tex.z-dn.net/?f=F%3D1.26%2A10%5E%7B-3%7DN)
Explanation:
Assuming the pith balls as point charges, we can calculate the repulsive force between them, using Coulomb's law:
![F=\frac{kq_1q_2}{d^2}](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bkq_1q_2%7D%7Bd%5E2%7D)
We observe that the magnitude of the electric force is directly proportional to the product of the magnitude of both signed charges(
) and inversely proportional to the square of the distance(d) that separates them.
Replacing the given values, where k is the Coulomb constant:
![F=\frac{8.99*10^{9}\frac{N\cdot m^2}{C^2}(-30*10^{-9}C)(-30*10^{-9}C)}{(8*10^{-2}m)^2}\\F=1.26*10^{-3}N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B8.99%2A10%5E%7B9%7D%5Cfrac%7BN%5Ccdot%20m%5E2%7D%7BC%5E2%7D%28-30%2A10%5E%7B-9%7DC%29%28-30%2A10%5E%7B-9%7DC%29%7D%7B%288%2A10%5E%7B-2%7Dm%29%5E2%7D%5C%5CF%3D1.26%2A10%5E%7B-3%7DN)

Explanation:
If the Maggie's mass is 100.0 kg and the truck is 1810 kg, calculate the magnitude of the net (unbalanced) force that can cause the acceleration.
Mollusks live
in fresh water, in marine environment, but also on land.
<span>Echinoderms
live only in water. This is the reason why they have developed different
systems for moving. Mollusks have only singular muskullus foot for walking and
Echinoderms have tube feet which they use for moving, as well for collecting
and transporting food to their mouth. </span>
Answer:
The correct answer is
Explanation:
Character 1: Why are these comic books so hard to read? Can u read them?
Character 2: No it's easy to read Tigger. It's because you are an animal an I am a human being. U don't know how to read.
Hope this helps....
Have a nice day!!!!
