Explanation:
It is known that octane is a hydrocarbon and London dispersion forces are the main intermolecular forces which are present in it.
Whereas water molecules tend to form hydrogen bonding forces which are actually much stronger than dipole-dipole interactions. This means that more energy is necessary to separate water molecules from one another than to separate octane molecules from one another.
Hence, we can conclude that surface tension of octane is expected to be lower than that of water when the two are considered at the same temperature.
Answer:
See answers below
Explanation:
vf = vi + gt
0 = (120sin55°) + (-9.8)t
t = 12.2 s
12.2 x 2 = 24.4 s
x = (vi)t + (1/2)at²
x = (120cos55°)(24.4) + 0
x = 64.79 m
a.
vf = vi + gt
0 = (120sin55°) + (-1.6)t
t = 74.98 s
74.98 x 2 = 149.96 s
x = (vi)t + (1/2)at²
x = (120cos55°)(149.96) + 0
x = 398.18 m
Answer:
the responding variable is the water boiling
Explanation:
a responding variable is the same thing as a dependent variable and an independent variable you change the independent variable is the amount of salt, the control group is how long water takes to boil without adding salt, and a constant is the same amount of water

The earth rotates (spins) at the same time as it orbits in a circular motion around the sun. fun fact : it takes 365 days to complete 1 orbit for 3 years and then 366 days for a leap year! you don't have to put that last part but maybe for some extra points you can!
