question 113

Multiple Choice

Radium-226 decays into radon-222 plus an alpha particle. The relevant masses are ${ } _ { 2 } ^ { 4 } \mathrm { He } : \quad 4.002603 \mathrm { u }$
$\begin{array} { l l } { } _ { 86 } ^ { 222 } \text { Rn: } & 222.017570 u \\ { } _ { 88 } ^ { 226 } \text { Ra: } & 226.025402 u \end{array}$

• A) \(4.87 \mathrm { MeV }\)
• B) \(5.39 \mathrm { MeV }\)
• C) \(3.76 \mathrm { MeV }\)
• D) \(5.05 \mathrm { MeV }\)
• E) \(4.24 \mathrm { MeV }\)

Sediment

Particles of rock, minerals, or organic materials deposited by water, wind, or ice, often forming layers that can turn into sedimentary rock.

Tributaries

Smaller rivers or streams that flow into a larger river or lake, contributing to its overall water volume.

Sediment

Particulate organic and inorganic material that settles at the bottom of a liquid, often transported by water, wind, or ice.

Discharge

The flow rate of water from a given source, such as a river or aquifer, typically measured in volume per unit time.
