Answer:
a) r = 6122 m and b) v = 32.5 m / s
Explanation:
a) The train in the curve is subject to centripetal acceleration
a = v2 / r
Where v is The speed and r the radius of the curve
They indicate that the maximum acceleration of the person is 0.060g,
a = 0.060 g
a = 0.060 9.8
a = 0.588 m /s²
Let's calculate the radius
v = 216 km / h (1000m / 1km) (1 h / 3600 s =
v = 60 m / s
r = v² / a
r = 60² /0.588
r = 6122 m
b) Let's calculate the speed, for a radius curve 1.80 km = 1800 m
v = √a r
v = √( 0.588 1800)
v = 32.5 m / s
Your break probably only took 20-30 minutes. Bacteria can double every 20-30 minutes. Hope this helped!

They are often arranged in a category
Answer:
14. D
15. It is showing a magnet pushing against itself and everything around with tremendous force.
16. D, because of how many forcefields in that area.
17. It is showing (both) that they are attracting and repealing.
18. I’m not sure sorry :(

A theory is an explanation that unites the findings of many experiments, and it can be changed when new experimental results need to be explained.
