By definition, of the law of ohm, we have to:
Where,
V: voltage
I: current
R: resistance
Therefore, we have that the relationship between voltage and current is proportional.
The proportionality constant for this case is the resistance.
For the current we have:
The proportionality constant for this case is the inverse of the resistance.
Answer:
A statement that describes the relationship of voltage and current is:
Voltage is directly proportional to current because I = V / R
Answer:
Explanation:
Most environments have many niches. If a niche is "empty" (no organisms are occupying it), new species are likely to evolve to occupy it. This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche.

Answer:
Word for the first blank: gravity
Word for the second blank: matter
Explanation:
The only way debris from the impact with Earth can be held close to Earth is due to a force. The only force that could be acting from Earth is "the force of gravity".
The gravitational pull of this new object being formed, increases proportional to its mass as more and more "matter" accumulates. And the accretion process is now on its way.
