The choice that is most likely end for a star that formed from an extremely large nebula would be a black hole. Gravity pulls so much in a black hole that no light exists.
Answer:
18 m
Explanation:
y = 10x − 5/9 x²
When the projectile lands, y=0:
0 = 10x − 5/9 x²
0 = x (10 − 5/9 x)
x = 0, 18
The range of the projectile is 18 m.
By blocking the UV rays that are emitted by the sun.

Answer:
1) Translational equilibrium(Net force =0) and rotational equilibrium(net torque=0)
2)m1/m2=r2/21
Explanation:
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
