If you could hear it at all, it would sound very soft.
Answer:
3m/s²
Explanation:
The slope on a velocity time graph represents the acceleration, so if you simply use the slope formula, you can find the acceleration between those two points.
m=rise/run
m=(60-15)/(20-5)
m=45/15
m=3 m/s ² squared (therefore this is your constant acceleration from those two points).
Hey There!
The atomic number represents the electrons and protons, therefore, if the atomic number of the element is 7 then there are 7 electrons and protons in the element.
In order to determine the amount of neutrons, you would subtract the atomic number from the atomic mass.
Hope this helped!

Explanation:
Define: Signals
Before going too much further, we should talk a bit about what a signal actually is, electronic signals specifically (as opposed to traffic signals, albums by the ultimate power-trio, or a general means for communication). When one speaks of analog one often means an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.
An analog signal uses some property of the medium to convey the signal's information. Any information may be conveyed by an analog signal, often such a signal is a measured change in physical phenomena, such as sound, light, temperature, position, or pressure.
For example, in sound recording, changes in air pressure (that is to say, sound) strike the diaphragm of a microphone which causes related changes in a voltage or the current in an electric circuit. The voltage or the current is said to be an "analog" of the sound.
