For the answer to the question above,
Velocity=distance/time
Data:
distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.
time=55 minutes
Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute
Data:
distance=1 mile.
velocity=0.113 miles/minute
time=distance /velocity
time=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes.
<span>So the answer is 8.86 minutes. </span>
A neutral atom contains equal amount of proton and
electron.
A negative ion contains extra electrons hence there is
additional outer shell so it is expected that the radius is bigger than that of
a neutral atom.
While a positive ion contains less electron so there is
less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
<span>positive ion, neutral atom, negative ion</span>
