Answer:
In this reaction, sodium hydroxide (NaOH) disassociates into sodium (Na+) and hydroxide (OH-) ions when dissolved in water, thereby releasing OH- ions into solution. Arrhenius acids are substances which produce hydrogen ions in solution. Arrhenius bases are substances which produce hydroxide ions in solution.
The momentum change =mass*velocity change. But sincevelocity change is not known another strategy must be used to find the momentum change. The strategy involves first finding the impulse (F*t = 1.0 N*s). Since impulse = momentum change, the answer is 1.0 N*s.
Answer: 6.64 × 10^ -6 m
Explanation:
for a constructive interference;
ρ= 2πm
remember that we are looking for the seventh bright side fringe.
so, m=7
ρ=14π
We now have to find the phase different
ρ`=2πx/ρ - 2πx/ρ
p` is the wavelenght in the mica. x= width of the mica wavelength in the mica.
ρ= ρ/n.
n= refractive index.
The phase will now be
ρ`= 2πx/ρ - 2πx = 2πx(n-1)/ρ.
ρ= ρ`
14π = 2πx (n-1)/ ρ
we now solve for x; x = 7ρ/n-1
x = 7(550× 20^ 9)/ 1.58 - 1
= 6.64 × 10^-6
