Answer:
1.It allows for movement.
2.t controls the breathing rate.
4. It controls the heart rate.
Explanation:
Answer:
The momentum of the system would be zero. A further explanation is described below.
Explanation:
- The quantity of direction of travel which always takes place throughout something which moves or perhaps the start forcing that continues to moves something forward to maintain its movement, recognized as Momentum
- As momentum varies depending on velocity, these were quantified by something that also relies mostly on direction including its body's natural movement.
Therefore the correct answer would be the one mentioned.
Answer:
The electrons in oxygen are paired while in nitrogen, they are not.
Explanation:
To analyse this we start with writing out the ground state electronic configurations for both elements.
Oxygen: 1s²2s²2p4 meaning the p subshell has the following arrangement of electrons ↑↓ ↑ ↑
Nitrogen : 1s²2s²2p³ meaning the p subshell has the following arrangement of electrons ↑ ↑ ↑
Clearly the paired electron in oxygen will be experiencing repulsion from the electron it shares an orbital with causing it to be removed easily. The electrons in nitrogen are unpaired, each orbital is singly occupied
