If a Substance conducts heat easily then it is considered a good conductor, since the electrons can move freely within the substance.
<span>A physical change is any change that alters the form or appearance of a substance but does not change it into another substance
-Some of the physical properties may be altered, but the chemical composition stays the same
-Examples: Bending, Crushing, Cutting, Melting, Freezing, Boiling</span>
Doing a force balance on the car:
ma = Fr
ma = μmg
a = μg
a = 0.3(9.81)
a = 29.43 m/s2
Using the formula:
2ax = v2
2(29.43)(34) = v2
v = 44.74 m/s = 161.05 km/h
The car was going 44.74 m/s or 161.05 kph when the brakes were applied.
Florine is special becaus Florine is at the highest value of electronegative value with 4.0
Its prominent ring system which is composed of primarily ice particles with smaller amounts of rocky detbris. Hope this helped!
