This type of data transmission is characterized by continuous information that may be actively changing and is generally characterized by a sin wave

The answer is an analog transmission. It is a continuous sine wave that varies in phase, amplitude or frequency. Measured in Heartz (Hz). The other is digital transmission that has discrete pulses, rather than continuous, and the pulses represent bits (1s and 0s) which can only be modulated by the voltage or intensity (in optical transmission). Measured in Bits per Second.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the atomic mass is the bottom number on the element.
