His average speed all the way is
(50 meters) / (5 sec) = 10 m/s .
But, if the acceleration is uniform all the way down, then
Average speed = (1/2) (start speed + end speed)
Start speed = 0.
So
Average speed = (1/2) (0 + end speed)
= (1/2) of end speed .
10 m/s = (1/2) of end speed
End speed (at the bottom) = 20 m/s .
Magnitude of acceleration = (change in speed) / (time for the change)
= (20 m/s) / (5 sec)
= 4 m/s² .
The answer is C, increasing atomic number.
Answer in my own words:
Research reveals that most of the indoor microplastics contained in the air are created by synthetic plastic fibres, as well as by textiles used in furniture
Key words:
1: Research
2: air
3: Plastic

Hi!
Neutrons are neutral, which means they don't exactly have an electrical charge. It's because of this neutral charge that it is represented with a '0'.
On the other hand, protons and electrons <em>do </em>have electrical charges. Electrons flow around the outside of the nucleus, with a negative charge.
Protons are stored in the nucleus with the neutrons, holding a positive charge.
Hopefully, this helps! =)
The speed of 4m/s means that the bike goes 4 meters for each second of movement. Multiplying this by 5 seconds we have a total distance travelled of 20m.
