Which statement will be true if you increase the frequency of a periodic wave

The number of waves per second will increase

Explanation:

The frequency of a wave is how many times the wave is repeated in a given time.

The larger the frequency, the more times per unit of time (in this case seconds) the wave will be repeated.

In addition, the frequency is inversely proportional to the wavelength, that is, at a higher frequency we get a lower wavelength. What this tells us is that the number of waves per second will increase.

In conclusion, when raising the frequency of the wave, the wave is repeated more times per second, which translates to a greater number of waves per second.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
