Explanation:
it is 2020 let's be honest all
Answer: D) All of the above
Explanation:
Burn rate can be affected by all of the above reasons as, variation in chamber pressure because the pressure are dependence on the burn rate and temperature variation in initial gain can affect the rate of the chemical reactions and initial gain in the temperature increased the burning rate. As, gas flow velocity also influenced to increasing the burn rate as it flowing parallel to the surface burning. Burn rate is also known as erosive burning because of the variation in flow velocity and chamber pressure.
Answer:
t = 2212 years
Explanation:
In radioactive decay processes it is described by the equation
N = N₀
to calculate the activity
= log 2 /λ
λ = log 2 / T_{1/2}
λ = log 2 /5715
λ = 5.267 10⁻⁵
now the amount of carbon 14 is N₀ = 0.1%, the sample contains an amount of N = 0.089%
N / N₀ = e^{-\lambda t}
-λ t = ln N / N₀
t = - 1 /λ ln N /N₀
t = 1 / 5.267 10⁻⁵ ln (0.089 / 0.1)
t = 2,212 10³ years
t = 2212 years
