Water waves in a tank are 10 cm long. If they pass a point at a rate of 3.75 waves per second, what is their speed in m/s?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

think its the third option

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
