Answer:
Chlorine and Fluorine
Explanation:
When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.
Answer:
C, H, N, O, P, S
Explanation:
carbon, hydrogen, oxygen, phosphorus, and sulfur are the 6 most common in biomolecules
Answer:
c. The less massive object will have less momentum if the velocities are the same.
Explanation:
p = mv
If the velocities are the same, p ∝ m, so the less massive object will have less momentum.
a. is wrong. If the masses are equal, p ∝ v, so the object with the higher velocity will have the greater momentum.
b. is wrong. If an object has both more mass and a greater velocity, it will have the greater momentum.
d. is wrong. If the velocities are the same, the more massive object will have more momentum.
The charge will most likely leave the electric field near C) Y
Answer:
the force it exert on track is
46600N
Explanation:
The car acceleration
a = V²/R
= (18.0m/s)²/(24.0)
= 13.5m/s²
net force
F(net) = m * a
= 2000kg * 13.5m/s²
= 27000N
F(net) = F₀ - F₁
where
F₀ = upward force
F₁ = downward force
F₁ = m * g
= (2000kg) * (9.8m/s²)
= 19600N
upward force which is F₀
F₀ = F(net) + F₁
= 27000N + 19600N
= 46600N
