Answer:
Unusually large moons form in giant impacts, which are relatively rare events
Explanation:
Solution:
- Finding large moons comparable in size to their planets result from impacts of two astro-bodies. The probability of such an event occurring is very rare.
- Even at the best luck, one moon can be made from the result of giant impact. While the probability of 6 planets having moons of comparable sizes is close to impossible. The transition from an undifferentiated cloud to a star system complete with planets and moons takes about 100 million years.
The two sides of the aluminium pop can have opposite charges. Overall the can is electricity neutral; it's just that the positive and negative charge has been separated from each other. We can say that the charge in the can has been polarized. In general terms, polarization means to separate into opposites.

Answer:
Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion.
Explanation:
The ball was released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
Answer:
a = R/2
Explanation:
Let R be the radius of the sphere and q = -2e be the charge in it. Let q₁ be the charge at radius a where the one of the point positive charges e is located. . Since the charge is uniformly distributed, the volume charge density is constant. So, q/4πR³ = q₁/4πa³
q₁ = q(a/R)³ = -2e(a/R)³. The electric force due to q₁ at r is F₁ = kq₁q/a² = kq²(a/R)³/a² = k(-2e)²a/R³ = 4ke²a/R³.
Let h be the distance between the two point charges. The electric force due to the one point charge on the other is F₂ = ke²/h²
If the net force on either charge is zero, then
F₁ = F₂
4ke²a/R³ = ke²/h²
a = R³/4h²
Since h = 2a, since the charges are equidistant from each other,
a = R³/4(2a)² = R³/8a²
a = R³/8a²
a³ = R³/8
a = ∛(R³/8)
a = R/2
