When you brew a coffee you're creating a Solution.
Tiny particles from coffee grounds, or solutes, are dissolved in water, the solvent.
Explanation:
It is given that,
Average power per unit mass generated by Lance,
(a) Distance to cover race,
Average speed of the person, v = 11 m/s
If t is the time taken to cover the race.
t = 14545.46 s
Let W is the work done. The relation between the work done and the power is given by :
W = 7090911.75 J
(b) Since,
So, in 7090911.75 J,
W = 1694.01 J
Hence, this is the required solution.
