For maximum radiation protection the suggested distance between array fan-beam scanner source and the operator is 2m.
The Fan beam 5 position reference system (PRS) uses accurate time-of-flight laser technology to determine vessel position relative to custom reflectors.
A fan beam allows only the measurement of the azimuth angle. A fan beam, one with a narrow beam width in azimuth and a broad beam width in elevation, can be obtained by illuminating an asymmetrical section of the paraboloid.
The operators’ desk should be positioned at least 1m away from a pencil beam, and at least 2m from a fan-beam system. Some older models, that are not now common, require a distance of 3.5 m.

Look at yourself in a plane mirror<span> and </span>you see<span> your </span>image<span> - it is upright. The </span>image <span>is located on the other side of the </span>mirror<span> since reflected rays diverge upon reflection; when </span>mirrors<span> produce </span>images<span> on the the opposite side of the </span>mirror, the images<span> are said to be virtual.</span>
Explanation :
It is given that :
The initial velocity of the car is 10 m/s.
Juliette sets the acceleration to zero.
We know that, acceleration \
where,
u is the initial velocity and v is the final velocity.
So, final velocity will become 10 m/s.
Hence, the car will move with the constant velocity i.e. 10 m/s.
So, Shakina described that the car will move with the constant velocity of 10 m/s as acceleration is zero.

Thanks me later, that's my answer.
