What it means: Thereâs blood in your pee, a condition called hematuria. That's never normal, so you should get it checked out as soon as possible,â Dr. Griebling says. Causes of bloody urine include trauma, kidney disease or cancer, inflammation or an infection in the kidneys, and more.
The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time. Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. A complete cycle is 360Â°. The waves are in phase if the waves are either 0 or 360Â° apart. The resulting amplitude (sum of the waves) is twice the original. They are out of phase if the resulting amplitude is between 0 and twice the original.
A sine wave is a good example of a repeating pattern of amplitudes, and in some ways it is the simplest. Thats why sine waves are sometimes referred to as simple harmonic motions. Lets arbitrarily fix an amplitude scale to be from â1 to 1, so the sine wave goes from 0 to 1 to 0 to â1 to 0. sine wave is a good example of a repeating pattern of amplitudes, and in some ways it is the simplest.
