Answer:
Here is every answer for analog and digital (in order)
Analog:
- Signal Shape: Smooth and continuous
- Numerical Values for Signal Measurements: Analog signals represent one continuous variable as the result of another continuous time-based variable. They are capable of outputting continuous information with a theoretically infinite number of possible values.
- Amount of Data that can be transmitted: analog circuits can conduct only fairly low-speed data communications. The maximum data rate over an analog facility is 33.6K bps when there are analog loops at either end. With 56K bps modems, only one end of the loop can be analog. The other end of the connection has to be digital.
- Energy requirements: light, sound, temperature, position, and pressure
- Privacy and security (ability of the signal to be encoded in a secret code): not encrypted
- Clarity of Signal: noise affects clarity and quality, noise is amplified, amplified noise causes more random information in the signal, signal bandwidth is low
Digital (in order):
- Signal shape: stepping, square, and discrete
- Numerical Values for Signal Measurements: digital communication methods transmit a complete measured value, in other words both a numeric value and a unit of measurement
- Amount of data that can be transmitted: First of all, it is theoretically possible to transmit digital signals directly. Unfortunately when we use capacitors and inductors (energy storage devices) to match the impedance from the transmitter to the air (low impedance transistor say 5 ohms to 388 ohms (air)) these components introduce a bandwidth limiting match. Since all impulse functions have infinite bandwidth (transmitting a 1 and a zero) the bandwidth of the transceiver must be multi octave in order to have any reasonable efficiency. Systems engineers simplify the problem by introducing direct sequence modulation where a carrier is modulated 0/180 degrees dependent on the data rate.
- Energy requirements: voltage, accoustic pressure, and magnetization of a magnetic storage media
- Privacy and security: encrypted
- Clarity of signal: noise is lower in amplitude, electronics can ignore the noise, quality of signal is maintained, signal is high

I did mine in bullet points, hopefully this helped!
Answer:
Volume of the concentrated solution, which is needed is 103.30 mL
Explanation:
Let's apply the formula for dilutions to solve the problem
Conc. Molarity . Conc. volume = Dil. Molarity . Dil volume
12.1 M . Conc. volume = 2.5 M . 500 mL
Conc. volume = (2.5 M . 500 mL) / 12.1M
Conc. volume = 103.30 mL

♨ The word ' acid ' is derived from the Latin word ' acidus ' which means sour. An acid is defined as the substance which gives hydrogen ions or protons ( H+ ) when dissolved in water. For example :
- Hydrochloric acid
- Sulphuric acid
- Nitric acid
- Carbonic acid
- Acetic acid
✎ 
☃ Physical properties :
- Acids have a sour taste. But some acids like steric acid, boric acid , salisylic acid do not have a sour taste. Laboratory acids are more corrosive , so they are dangerous to taste.
- Acid turn blue colour of litmus paper into red and light yellow methyl orange into red. They make phenolphthalein colourless.
☂ Chemical properties :
- Acids have a high dissolving power and dissolve many substances. Some metals like zinc and magnesium react with acids like dilute sulphuric acid and dilute hydrochloric acid to produce salt and hydrogen gas.
- Acid react with base to give salt and water.
- Acid gives H+ ions when dissolved in water.
- Acid react with metallic carbonates to produce carbon dioxide.

A weather front or front is a
narrow region between two air masses of different densities. Because of the
difference in density between warm and cold front, cold air tends to go
underneath the warmer air. It often creates the strongest winds above the
ground surface. This is caused due to the heat and mass transfer between
particles of air. They can be slowed down by the presence of mountains and
valleys. Cold air moves fast and the temperature around it can be felt as if
you are blown away due to its density. Whereas warm air moves slowly.
