Answer:
r = 0.137 m
Explanation:
The electric force is given by the Coulomb equation
F = k q₁ q₂ / r²
where k is the constant of Coulomb that is worth 8,988 10⁹ N m²/C², q₁ and q₂ are the charges and r is the distance that separates them
r² = k q₁q₂ / F
r = √ k q₁q₂ / F
let's calculate
r = √ (8.99 10⁹ 2.8 10⁻⁶ 7.5 10⁻⁶⁶ / 10
r = √ (1,8879 10⁻²)
r = 0.137 m
You answer is b an oscillating wave
To increase the number of snowmen destroyed, you would want more energy and all of the above would increase the energy of the system so D.
C Evolution says the universe began as a point and expanded
Because it’s on the bottom, and to get to that part of it, think of it like that scene from moana when they go down into the realm of monsters they go through the thick parts to get to the thin parts, soo the cube wouldn’t be nearly able to reach that level
