This seems like a question from an electrical course, and is probably best answered by your course materials.
It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.
An analog signal is simply a quantity varying continuously over time..But because we are interested in information and communication, we are usually interested in rapidly varying signals that have some underlying periodicity. Therefore we use sin wave
One with a continuous signal wave.

The sampling rate
No and yes. Digital signals are usually square or pulse waves. By Fourier analysis, however, every periodic wave, even a square wave, is the summation of some series (often infinite) of sine waves.
It's usually analog, but digital signals can be converted, if needed.
The normal points in the direction that the wave is traveling.
like a guitar sound!!!
It differs depending on who is saying it.
A tsunamis has a wave that is longer in length and looks like a fast rising tide rather than a traditional wave. A tidal wave is a wave that can reach as about a hundred feet tall and will look like a normal wave.
It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.
Convection waves are invisible: You can't see them.
A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of wave propagation. A common example is a sound wave, where the vibration of air molecules creates compressions and rarefactions that travel through the air.
ANALOGUE COMPUTERS ARE THE COMPUTERS WHICH PROCESS DATA IN A WAVE FORM WHILE HYBRID COMPUTERS POSSESS DATA IN BOTH DISCREET AND WAVE FORMS.
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.
A sound wave is represented by a series of compressions and rarefactions traveling through a medium. In a graphical representation, a sound wave appears as a wave-like pattern with peaks and troughs. The frequency of the wave determines the pitch of the sound, while the amplitude represents the volume.
Before it was eroded into its current wave-like shape, Wave Rock in Hyden, Australia looked like a typical granite rock outcrop with a smooth, sloping surface. Over millions of years, the softer rock beneath it eroded away, leaving behind the striking wave formation we see today.
