Many towns in flood-prone areas are surrounded by___ that are built to hold back rising water.
xxTIMURxx [149]

Answer:

Flood barriers

Explanation:

Many towns in flood-prone areas are surrounded by flood barriers that are built to hold back rising water during seasonal highs.

  • Flood barriers are water resistant walls that are used to prevent breaking water during a high period of inundation from their channels.
  • They are usually vertical artificial structures which can be temporary or permanent.
  • They help to hold or contain the flood water during the high season.
  • These walls prevents flood plains and other nearby areas from getting flooded during the rainy season.

While exploring a coal mine, scientists found plant fossils in the ceiling of the mine which had been preserved by an earthquake
ale4655 [162]

Answer:

11552.45 years

Explanation:

Given that:

Half life = 5730 years

t_{1/2}=\frac{\ln2}{k}

Where, k is rate constant

So,  

k=\frac{\ln2}{t_{1/2}}

k=\frac{\ln2}{5730}\ years^{-1}

The rate constant, k = 0.00012 years⁻¹

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

Given that:

The rate constant, k = 0.00012 years⁻¹

Initial concentration [A_0] = 160.0 counts/min

Final concentration [A_t] = 40.0 counts/min

Time = ?

Applying in the above equation, we get that:-

40.0=160.0e^{-0.00012\times t}

e^{-0.00012t}=\frac{1}{4}

-0.00012t=\ln \left(\frac{1}{4}\right)

t=11552.45\ years
