Answer:
The correct answer to the question is
a. a compound that conducts electricity when molten
Explanation:
A molecular is solid comprises of a collection of molecules combined together by van der Waals forces and not having covalent or ionic bonds. They are made up of forces atoms or molecules combined by dipole-dipole forces, London dispersion forces or hydrogen bonds. Exmples include graphite and diamonds. The forces between the molecules in molecular solid is also known as intermolecular forces (IMFs)
The expression for the wave function describing this wave is y(x,t) = 0.02 sin(17.95x + 75.4t - 0.00198).
The angular frequency of a wave is 75.4 rad/s.
<h3>
What is wave function?</h3>
A wave function is a mathematical equation for the motion of the wave.
y(x, t) = A sin(kx + ωt + Φ)
where;
- ω is angular speed
- k is angular wavenumber
- Φ is phase angle
The angular wave number of the wave is calculated as follows;
k = 2π/λ
where;
- λ is the wavelength
- k is the angular wavenumber
k = 2π / 0.35
k = 17.95/m
<h3>Angular speed</h3>
ω = 2πf
ω = 2π(12)
ω = 75.4 rad/s
<h3>Phase angle</h3>
75.4(0.2) sin(Φ) = -0.03
sin(Φ) = -0.001989
Φ = arc sin(-0.001989)
Φ = -0.00198
<h3>Wave function</h3>
y(x,t) = 0.02 sin(17.95x + 75.4t - 0.00198)
Thus, the expression for the wave function describing this wave is y(x,t) = 0.02 sin(17.95x + 75.4t - 0.00198).

Answer is B. Atoms must be bonded together to create molecules.
Answer:
C) Both 1 and 2
Explanation:
The scan tool may include a bi-directional control that allows the technician to control the output of the alternator for testing purposes.
The Diagnostic Trouble Codes (DTCs), are used by automobile manufacturers to diagnose problems related to the vehicle.
The scan tool can also be used to monitor the output voltage of the vehicle to verify if the correct amount of voltage is supplied by the alternator.
Both Technicians A and B are correct because the steps they both take are necessary for the diagnosis of the vehicle.
