The distance between 4 nodes (3 sections, 2 sections=a wavelength) is 15.0 cm. The frequency of the source is 10.0 Hz. What is the speed of the
waves in cm/s?
A) O 75.0 cm/s
B). 1.50 x 10^2 cm/s
C) 2.00 x 10^2 cm/s
D) 9.00 x 10 cm/s
E) 1.00 x 10^2 cm/s

i think they are all correct

explanation:

they seem good

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.
