Answer:
Technician B
Explanation:
There's no such thing as a perfect filter available to block any kind of toxic fumes. The effectiveness of a filter depends of various things, such as the air flow and the particles size. They have specific rates depending on the place they are designed to be installed on, so they have to be chosen with that in mind. For example, most industrial applications have more demanding restrinctions than a commercial one, so a filter designed for the latter would probably not be useful for the first case.
Given that,
s = √(2t + 1)
Time, t = 4 s
Acceleration , a = ??
Since,
Acceleration = velocity / time
Velocity = distance/ time
Acceleration = distance/ time²
s/t² = √(2t+1)/t²
putting t = 4 sec, we have
a = √(2*4+1)/4²
a = √(5)/16
a= 0.139 ft/s²
Therefore, acceleration of the given particle will be 0.139 feet/ second².

Answer:
Time zone is one important factor in difference in location and this in turn affects the result of the resolution and rotation of shadow produced from the sun or other illumination.
Therefore someone at a place might see a clear large shadow due to shinny sun reflection and another a small or dull Shadow at same time if the intensity of the sun or lighting source is going down.
Explanation:
The closer a body/object is to a lighting source the larger the shadow it produces, and the farther the body the smaller the shadow produced.
