There is no gravity in orbit/space to pull them toward a certain area so they have full movement and that is why they float
The answer is believed to be C because the evidence is from fossils and glaciers.
Answer:
If all these three charges are positive with a magnitude of each, the electric potential at the midpoint of segment would be approximately .
Explanation:
Convert the unit of the length of each side of this triangle to meters: .
Distance between the midpoint of and each of the three charges:
Let denote Coulomb's constant (.)
Electric potential due to the charge at : .
Electric potential due to the charge at : .
Electric potential due to the charge at : .
While forces are vectors, electric potentials are scalars. When more than one electric fields are superposed over one another, the resultant electric potential at some point would be the scalar sum of the electric potential at that position due to each of these fields.
Hence, the electric field at the midpoint of due to all these three charges would be:
.
Answer:ball, ramp, and angle
Explanation: these are the three things that are controls because you can control them
