When a resistor is connected to a 12 volt source, it draws a 185 mA current. what's the resistance? (I said 65 ohms). the same resistor connected to a 90 volt source draws a 1.25 amp current. what's the resistance? is it ohmic?

Which sequence of processes must occur for an atom of carbon to go from a human to a car? A- respiration, photosynthesis, decomposition. B- fossilization, decomposition, respiration. C- photosynthesis, combustion, respiration. D- respiration, fossilization, photosynthesis.
How do you calculate wavelength with distance? I know that it's 4L for the first harmonic of a closed end column but what is it for an open ended column or a column with one end open, one end closed? Why does it work like that?
