Mass divided by volume is density, while mass times density is volume. you cannot calculate density without volume and you cannot calculate volume without density.
i believe that's the answer.
oh gosh i didn't realize my middle school education involved high school stuff.
Answer:
Explanation:
Using Newton's second law, we calculate the magnitude of the electric force between the spheres:
The magnitude of the charge in both spheres is the same. So, we calculate the charge, using Coulomb's law:
Answer:
2,54 cm are equal to 1 inch
Explanation:
Doing the conversion:
The definition of speed is (distance covered) / (time to cover the distance) .
So a unit of speed has to be (a unit of length) / (a unit of time) .
Here are several perfectly fine units of speed:
-- miles per hour
-- feet per second
-- meters per second
-- kilometers per hour
-- inches per second
-- centimeters per minute
-- yards per Century
-- furlongs per fortnight
-- nanometers per microsecond
-- Smoots per week
-- parsecs per millenium
