Answer:
19.8m/s
Explanation:
Given parameters:
Mass of the ball = 10kg
Height of the rail = 20m
Unknown:
Velocity at the bottom of the rail = ?
Solution:
The velocity at the bottom of the rail is its final velocity.
Using the appropriate motion equation, we can find this parameter;
V² = U² + 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
the ball was rolled from rest, U = 0
V² = O² + 2 x 9.8 x 20
V = 19.8m/s
Answer:
any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g., iron, manganese, chromium, and copper. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.

Because there is so much suger thats how it is so sweet and people like it!
The complete statement will be "Support gases system are subject to the same hazards as, present in any piped medical gas system with the additional hazard of higher pressure"
<h3>What are gas systems?</h3>
Generally, A gas system is simply defined as an assemblage of tubes, used for gas reticulation and circulation.
In conclusion, a higher pressure will be experienced as an additional hazard to the medical gas system.
