<h3><u>Answer;</u></h3>
C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.
<h3><u>Explanation;</u></h3>
- <em><u>Covalent bond is a type of bond that results from the sharing of electrons between two non-metal atoms. </u></em>
- <em><u>Ionic bond on the other is a type of bond that results from the transfer of electrons between metal atoms and non metal atoms, where a metal atom looses electrons and a non-metal atom gains electrons.</u></em>
- <em><u>The amount of energy required to break an given bond determines how strong a particular bond is.</u></em> Ionic bonds require more energy to break as compared to covalent bond and therefore they are stronger than the covalent bonds.
Answer: 1.32 m/s^2
Explanation:
Centripetal acceleration is given by the formula
a = ( v^2 ) / r
where a is centripetal acceleration, v is velocity and r is radius.
We know that,
v = 5 m/s
r = 19m
Now,
a = ( v^2 ) / r
a = ( 5^2 ) / 19
a = 25 / 19
a = 1.32 m/s^2
Answer: D) All of the above
Explanation: Matter waves are examples of wave particle duality. Matter waves, reflect, refract, diffract, and interfere just like light or water waves. Matter waves have amplitudes, wave speeds, wavelengths, and frequencies.
