A <u>scanner</u> is a type of communications equipment that functions as a radio receiver and searches across several frequencies.
A scanner is a kind of a radio receiver that has the ability to receive multiple signals.
There are three modes which a scanner uses for acting as a radio receiver. The scan mode of the radio receiver constantly changes frequencies that helps in transmissions. There is also a manual scan mode that allows the users to search for their interested frequencies. The search mode allows the users to search through two sets of frequencies.
A scanner is a type of communication equipment that is easy to use with various features such as the volume, numeric keypad, trunk tracking etc.

Answer:
The correct one is that the force on B is half of the force on A
Explanation:
Because radius for the inside of the curve is half the radius for the outside and Car A travels on the inside while car B, travels at equal speed on the outside of the curve. Thus force on B will be half on A
B. Deflate because volume is inversely proportional to temperature
Answer:
The work done in stretching the spring is 0.875 J.
Explanation:
Given that,
Force = 140 N
Natural length = 60-40 = 20 cm
Stretch length of the spring = 65-60 = 5 cm
We need to calculate the spring constant
Using formula of Hooke's law




We need to calculate the work done


On integration



Hence, The work done in stretching the spring is 0.875 J.
