The two waves shown here are the same distance from point x and are traveling toward each other

Answer:
A). 0.0 cm
Explanation:
When two waves travel and meet at the same point, a phenomenon known as interference occurs.
The two extreme cases of interference are the following:
- When two waves in phase meet at the same point, the resultant wave produced by the interference has amplitude which is the sum of the amplitude of the individual waves
- When two waves in anti-phase meet at the same point, the resultant wave produced by the interference has amplitude which is the difference between the amplitudes of the individual waves
In this problem, we have two waves of amplitde A1 = 2.0 cm and A2 = 2.0 cm that meet at X in anti-phase (because they have opposite displacement): therefore, it is a destructive interference, and the resultant amplitude will be

Answer:
The current will be increased and also for the resistance.
Explanation:
The analysis of a direct current circuit can give us the explanation we need. Using the ohm law, which tells us that the voltage is equal to the product of the current by the resistance we have:
The voltage is equal to the potential difference therefore we will have these expressions:
If we increase the potential differential or circuit voltage, the current will also increase and so does the resistance by increasing the voltage. If we put numerical values in the equation given before, we can confirm this fact.
