Answer:
The Girl will go up and the Boy will go down
Explanation:
In order to find out the answer to this problem, you need to know how to find the unit rate. A unit rate a rate that has a denominator of 1. You find the unit rate because the problem is asking you to find the faster speed, but the ratios are different.
So 600m in 60 sec you divide both by 60. It comes out as 10m in 1 sec for the heron.
60m in 5 sec is 12m in 1 sec for the duck.
Compare the heron to duck. The heron travels faster.

Answer:
Explanation:
The electron in the lowest energy state will be found in 1 s energy level.
set of 4 possible quantum numbers
Principal quantum no : n = 1 ,
Azimuthal quantum no l = 0
Magnetic quantum no m = 0
Spin quantum no s = + 1/2
set of other quantum nos
Principal quantum no : n = 1 ,
Azimuthal quantum no l = 0
Magnetic quantum no m = 0
Spin quantum no s = - 1/2
We need to keep in mind that the compound is neutral.
H2SO3
2(+1)+S+3(-2)=0 (since its neutral)
2+S-6=0
S-4=0
S=4
Therefore the oxidation number for sulfur is +4.
