Answer:
Sometimes
Explanation:
Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.
like a black cloud
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.
Answer:
Approximately 
.
Explanation:
Note that the electric rate in this question is in the unit dollar-per-
, where 
is the energy to run an appliance of power 
for an hour.
Number of minutes for which the air conditioner is running in that day: 
. Apply unit conversion and ensure that this time is measured in hours (same as the unit of the electric rate.)
.
The power of this air conditioner is:
.
Thus, the energy that this air conditioner would consume would be:
.
At a rate of 
dollar-per-, the cost of that much energy would be approximately 
dollars (rounded to the nearest cent.)
