<span>The elements on the Periodic Table are arranged in order of increasing "Atomic number"
In short, Your Answer would be Option B

F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
Answer:
lbm/ft³ or psi/ft
Explanation:
The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.
NOTE:
"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass
"psi" means "pound per square inch"; is also a unit for mass or weight
Answer:
2 166/4917 m/s
Explanation:
Speed= distance÷time
Speed=100÷49.17=2 166/4917 m/s
