The rate constant is 0.058/days and the population after 18 days is 412.38.
<h3>What is rate constant?</h3>
The rate constant of the population is calculated as follows;
N = N₀(2)^(rt)
where;
- r is the rate constant
- t of double of the population
when the population doubles, t = 12 days
2N₀ = N₀(2)^(12r)
2 = (2)^(12r)
ln(2) = 12r
r = ln(2)/12
r = 0.058/days
<h3>Population size after 18 days</h3>
The population size after 18 days is calculated as follows;
N = 200(2)^(0.058 x 18)
N = 412.38
Thus, the rate constant is 0.058/days and the population after 18 days is 412.38.

Answer:
just use the formula λ = v/f
Explanation:
v = velocity
f = frequency
so to increase Ue by 16 times you gotta reduce R(distence) by 16 times
I hope that helps you!!!!!!

b)1.6×10³
Explanation:
Given:
Boltzmann's constant (K)=1.38×10^-23 J/K
atmoic mass of helium = 4 AMU or 4×1.66×10^-27kg
a)The formula for RMS speed (Vrms) is given as
where
K= Boltzmann's constant
T= temperature
m=mass of the gas
b) RMS speed of helium when the temperature is doubled
