Answer:
(b) 64000
Explanation:
Assuming that the "Memo" being mentioned is a Microsoft Access memo field, it can hold up to 64,000 characters, even in the more recent version of the application where the "Memo" is now know as the "Long Text" field.
According to microsoft.com, "In earlier versions of Access, we used the Memo data type to store large amounts of text... the Long Text field works the same as the Memo field of old... [it] can only display the first 64,000 characters."

Answer:
-
= 1
= 1
Explanation:
Argon atom has atomic number 18. Then, it has 18 protons and 18 electrons.
To determine the quantum numbers you must do the electron configuration.
Aufbau's principle is a mnemonic rule to remember the rank of the orbitals in increasing order of energy.
The rank of energy is:
1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7d
You must fill the orbitals in order until you have 18 electrons:
- 1s² 2s² 2p⁶ 3s² 3p⁶ : 2 + 2 + 6 + 2 + 6 = 18 electrons.
The last electron is in the 3p orbital.
The quantum numbers associated with the 3p orbitals are:
= 1 (orbitals s correspond to
= 0, orbitals p correspond to
= 1, orbitals d, correspond to
= 2 , and orbitals f correspond to
= 3)
can be -1, 0, or 1 (from -
to +
)
- the fourth quantum number, the spin can be +1/2 or -1/2
Thus, the six possibilities for the last six electrons are:
- (3, 1, -1 +1/2)
- (3, 1, -1, -1/2)
- (3, 1, 0, +1/2)
- (3, 1, 0, -1/2)
- (3, 1, 1, +1/2)
- (3, 1, 1, -1/2)
Hence, the correct choice is:
-
= 1
= 1
None of it passes through. Most of the light is either reflected by the object or absorbed and converted to heat. Materials such as wood, stone, and metals are opaque to visible light.
Good luck
