Answer:
1.52g
Explanation:
Given parameters:
Force = 125N
Mass combined = 82kg
Unknown:
Acceleration of the bicycle = ?
Solution:
From Newton second law of motion suggests that:
Force = mass x acceleration
Acceleration = = = 1.52g
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:
