B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.

The magnitude of the circuit current is 0.20 A. The value of the current in the circuit is found with the help of the ohm's law.
<h3>What is ohm’s law?</h3>
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
All the resistance combined in the series so that the equivalent resistance is;

This current-voltage connection may be expressed mathematically by the Ohm's Law;
V=IR

Hence, the magnitude of the circuit current is 0.20 A.

Explanation:
The Specific Heat Capacity of silver is 230 J/kgK, melting point is 961.8 C so the difference is 941.8K. Now we simply do q=230J/kgK*16.5kg*941.8K and that is 3 574 131 J
