A classic example is a remote control. The mechanical force exerted by pressing the switches produces electric current (often times creating the electrical continuity of contacts when switch is pressed) within the remote control device allowing it to send radio signals to the receiver.

Answer: Remote control.

Explanation: The most classical example of a device that is used with this objective is the remote control (or clicker).

While the first remote controls used ultrasonic pulses, nowadays they use infrared radiation (there are other types, but this is the most common one), this is what allows them to work from distance. There are "codes" in the radiation that are read by a "camera" and are interpreted for things like turn on the power (and other things, maybe control a drone, change the channel, etc).

The product PV, where P and V represent pressure and volume respectively, is a unit for which?
Basile [38]
<span>PV is actually energy. P = F/A force per area, and V = A L, so PV = F L and force times distance is work which is energy. If you have P in N/m^2 and V in m^3, you have Joules, N-m.</span>

Which data set has the largest range?
MrRissso [65]

Answer:

Option C

Explanation:

We have to check range of all options first

For A:

Largest Value: 5

Smallest Value: 1

So range = Largest value - smallest value

5-1 = 4

For B:

Largest Value: 6

Smallest Value: 4

Range = 6-4 = 2

For C:

Largest Value: 9

Smallest Value: 1

Range = 9-1 = 8

For D:

Largest Value = 9

Smallest Value = 3

Range = 9-3=6

So, the data set in option C has the largest range

What is relative density?​
Artemon [7]
Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature.
