Answer:
The concentration of a chemical substance expresses the amount of a substance present in a mixture.
Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration is usually expressed in terms of mass per unit volume.
Speed = Starting speed + (time + acceleration)
Starting speed is 0, acceleration is 2 m/s, speed is 30
30 = 0 + 2t
t ( stands for time ) = 15
Answer:
c must have units of distance/time^2
Explanation:
Since y must be in units of distance, then all the terms that add up to give "y" must all have units of distance. That means that also the last term c * t^2 has units of distance, and therefore, if the product of c times t^2 produces a distance, then c must have units of distance divided the square of time units, so when multiplied by t^2 the time units in denominator and numerator cancel out.
