Answer:
As a positively charged object moves toward another positively charged object, their potential energy increases. True
As a negatively charged object moves toward another negatively charged object, their potential energy increases True
Explanation:
When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.
However, potential energy is inversely related to the distance of separation of the charges.
It gets into the atmosphere through evaporation, it wafts round as clouds and water vapor, then eventually precipitates out somewhere as rain or snow. This enters it into the biosphere, because every living thing on Earth needs water, and obviously in to the hydrosphere because... water is water. As moving water (streams, glaciers, etc.), it weathers and erodes the geosphere (the lithosphere is part of the geosphere). Deep down where rocks become sedimentary or metamorphosed, water also influences what kind of rock you get (as is also the case with cooling lava, but that's basically water at its first stage of entering the cycle).
Answer:
34 m/s
Explanation:
Centripetal acceleration is:
a = v² / r
Given a = 6.55 × 9.8 m/s² = 64.2 m/s², and r = 18 m:
64.2 m/s² = v² / (18 m)
v = 34 m/s
The speed of the centrifuge is 34 m/s.
