Wave speed = frequency * wavelength
Wave speed = 4 * 25
Wave speed = 100 m/s

I have no idea but this is my best guess as a sophomore in college
The standard wave format for any wave is transverse wave
Answer:
Increases.
Explanation:
The electric potential increases when the two positive charges of same magnitude bring close to one charge to another because there is repulsive force between them due to same charge and when the two opposite charges move away from each other, the potential energy decreases. When two opposite charges are brought closer together, electric potential energy decreases while on the other hand, when we move opposite charges apart from each other than the work done against the attractive force that leads to an increase in electric potential energy.
