B.
technically it would depend if the resistors were in series or parallel but B is the answer.
Answer:An ellipse is a closed curve consisting of points whose distances from each of two fixed points (foci) all add up to the same value .
Explanation:
Take into account that in a standing wave, the frequency f of the points executing simple harmonic motion, is simply a multiple of the fundamental harmonic fo, that is:
f = n·fo
where n is an integer and fo is the first harmonic or fundamental.
fo is given by the length L of a string, in the following way:
fo = v/λ = v/(L/2) = 2v/L
becasue in the fundamental harmonic, the length of th string coincides with one hal of the wavelength of the wave.
Answer:
Hey Krista: Burning is a type of chemical change using fire and heat that produces new substances "Buming"* things like wood or bread changes their color and odor
This is the best discription because it describes what things can burn and what happens to them.
*i don't know what "buming" means but i think you mean burning, lol.
