Answer:
The Arsenic has three electron-containing orbitals. The orbitals s, p and d.
Explanation:
Arsenic is an element with an atomic number equal of 33, it means that it has 33 electrons in its orbitals in the following way:








Therefore, the Arsenic has three electron-containing orbitals (s, p d).
From the calculation, we can see that the force that moves the box forward is 5.7 N.
<h3>What is frictional force?</h3>
The term frictional force refers to the force that opposes motion. Given that;
ma = ukmgcosθ + F
Let F be the forward force.
Hence;
F = ma - ukmgcosθ
F = 4 * 3 - (0.32 * 4.00 * 9.8 * sin 30)
F = 5.7 N
