Bones are primarily made of calcium. Also, they protect the body, which is pretty much obvious. They also act as camouflage.
The only but I have is, can they be found as a filler in most household?

Answer: actually the fastest 100m is 9.58, because i run at a 9.86
Explanation: but 10.44 is like 15 mph, 9.58 is 28 mph
Yes it is consider biology
Answer:
a battery, wires, and a switch.
Explanation:
All circuits include?
Given that,
Initial velocity , Vi = 0
Final velocity , Vf = 40 m/s
Acceleration due to gravity , a = 9.81 m/s²
Distance can be calculated as,
2as = Vf² - Vi²
2 * 9.81 *s = 40² - 0²
s = 81.55 m
For half height, that is, s = 40.77m
Vf= ??
2as = Vf² - Vi²
2 * 9.81 * 40.77 = Vf² - 0²
Vf² = 800
Vf = 28.28 m/s
Therefore, speed of roller coaster when height is half of its starting point will be 28 m/s.
