The only stable isotope of fluorine is F is F¹⁹which has one fewer neutron and displays β + decay of radioactivity
What is Beta decay (β+ decay)?
- In nuclear physics, beta decay, also known as β-decay, is a type of radioactive decay in which an atomic nucleus emits a beta particle (a fast energetic electron or positron), which changes the original nuclide into an isobar of that nuclide.
- For instance, in so-called positron emission, a proton is transformed into a neutron by the emission of a positron along with a neutrino, while in beta decay a neutron is transformed into a proton by the emission of an electron along with an antineutrino.
- Prior to beta decay, neither the beta particle nor the associated (anti-)neutrino are present in the nucleus; instead, they are produced during the decay process. This procedure gives unstable atoms a protons-to-neutrons ratio that is more stable.

Answer:
an increase in equilibrium price and an indeterminate effect on equilibrium quantity.
Explanation:
An inferior good is a good whose demand increases when income falls and reduces when income rises.
If ramen is an inferior good, when income falls its demand would increase. This would lead to a rise in quantity and price.
An increase in the price of wheat would increase the cost of production of ramen. As a result, the supply of ramen would fall. Price would increase and supply would fall.
The combined effect would be an increase in equilibrium price but an indeterminate effect on equilibrium quantity.

Answer:
Net income of Y3K, Inc. is $155.83
Explanation:
Debt-to-equity ratio is calculated by using formula:
Debt-to-equity ratio = Total debt (or liabilities)/Total equity
Total debt (or liabilities) = Debt-to-equity ratio x Total equity = 1.1 x Total equity
Basing on accounting equation:
Total assets = Total liabilities + Total equity = 1.1 x Total equity + Total equity = 2.1 x Total equity
Total equity = Total assets/2.1 = $2,975/2.1
Return on equity (ROE) = Net income/Total equity
Net income = Return on equity (ROE) x Total equity = 11% x ($2,975/2.1) = $155.83
