Answer
b. the number of atoms in each molecule.
Explanation:
This is the same question as the one previously but with more details, so I will just use my previous answer.
1800 to 1820 is 20 minutes.1830 to 1838 is 8 minutes.1840 to 1905 is 25 minutes.
The total time travelled is 20+8+25 = 53 minutes = 3180 seconds.
The distance between Glasgow and Edinburgh is 28 + 12 + 34 = 74 km = 74000 m.
So, the average speed is 74000m/3180s = 23.27 m/s (4 s.f.)
Newton's Second Law would probably best describe this.
F = ma
Where F = force
m = mass
a = acceleration
The force required is dependant on the mass, and where the mass is greater, the force required will be greater.
