Answer:
The following formula is used to calculate the speed or velocity of a wave. V = f * w Where V is the velocity (m/s) f is the frequency (hz)
Answer:
Explanation:
Hello!
In this case, since the reaction between hydrogen and oxygen to produce water is:
When equal masses of each reactant go in contact to carry out the reaction, we can identify the maximum mass of yielded water as the fewest mass yielded by each reactant, just as shown below:
Thus, since hydrogen yields more water than real, we limit the maximum mass of water to those 55.2 g yielded by oxygen as hydrogen would be in excess.
Best regards!
Two or more substances that are blended together but not chemically combined make up a mixture.
Answer:
By ensuring she is giving speed endurance training
Explanation:
Speed endurance training would be the most ideal in helping an athlete to maintain and even increase her competitive potential.
The speed endurance training would help the athlete maintain and attain a high speed for a longer duration of time.
This would make the athlete get used to running an improved time for much longer distances.
