The bulk of earths atmospheric oxygen comes from phytoplankton, small flower like things in the ocean.
Answer:
s (l = 0) only two electrons
p (l = 1) sublevel six (6) electrons fit
d (l = 2) sub-level has 10 electrons
f (l = 3) has 7 has 14 electrons
Explanation:
The electrons have an odd spin, so they must comply with the Pauli principle, therefore only two electrons fit in a given sublevel.
Sub level s (l = 0) only two electrons
Sub level p (l = 1) has three orbitals in which two electrons fit, therefore in the sublevel six (6) electrons fit
Sub-level d (l = 2) has 5 orbitals each with two electrons, the sub-level has 10 electors
Sub-level f (l = 3) has 7 orbitals and two electrons each, the sub-level has 14 electrons
Answer:
2.5 m/s^2
Explanation:
the formula for acceleration (or the one you use in this case) is a=vf-vi/t
where vf is equal to final velocity, vi is equal to initial velocity, and t is equal to time.
vf= 25 m/s
vi= 0m/s
t=10s 25-0=25, 25/10=2.5 therefore it is 2.5m/s^2
Answer:
57.1 km/hr
Explanation:
To find the average speed you take the total distance divided by the total elapsed time.
So, the total distance is 140 + 60 = 200
the total elapsed time is found by taking 140/70=2 and 60/40=1.5
2+1.5=3.5
The plug the numbers into the equation,
200/3.5=57.1
