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.

The answer is A. Determining the order of rock layers
Answer:
it speed is 264 kinetic energy
Answer:
velocity of rocket at the time of impact is 48.28 m/s
Explanation:
given,
rise of the rocket = 78 m
Velocity acquires by the rocket = 40 m/s
final velocity = 0 m/s
v = u + gt
0 = 40 - 9.81 × t
t = 4.08 s
now, calculation of displacement
![s = u t + \dfrac{1}{2}gt^2](https://tex.z-dn.net/?f=s%20%3D%20u%20t%20%2B%20%5Cdfrac%7B1%7D%7B2%7Dgt%5E2)
![s = 30\times 4.08 - \dfrac{1}{2}\times 9.81\times 4.08^2](https://tex.z-dn.net/?f=s%20%3D%2030%5Ctimes%204.08%20-%20%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%209.81%5Ctimes%204.08%5E2)
= 40.8 m
total height = 40.8 + 78 = 118.8 m
velocity = ![\sqrt{2gh} = \sqrt{2\times 9.81\times 118.8 }](https://tex.z-dn.net/?f=%5Csqrt%7B2gh%7D%20%3D%20%5Csqrt%7B2%5Ctimes%209.81%5Ctimes%20118.8%20%7D)
v = 48.28 m/s
velocity of rocket at the time of impact is 48.28 m/s
Out of these, I have to say the answer is "Washing fruit"
