The decrease in the water table due to overuse of water.

1 answer:

4 0

Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

If the average rate of sediment accumulation is 3 cm/1000years, how long would be required for sediments to completely bury seam

stira [4]

Answer:

500,050000 years

Explanation:

Given that :

Rate of Accumulation = 3cm/ 1000 years

Height of seamounts = 1.5km

Representing height of seamounts in cm;

(1.5 *1000 * 100) = 1500150 cm

Time taken = height / rate

Time taken = (1500150 cm / 3cm) * 1000

Time taken = 500,050000 years

(a) what is the approximate ductility (%el) of a brass that has a yield strength of 230 mpa (33360 psi)?

ss7ja [257]

Based on the calculations, the approximate ductility (%el) of this brass is equal to 2.3%.

<u>Given the following data:</u>

Yield strength = 230 mpa (33360 psi).

<h3>What is ductility?</h3>

Ductility can be defined as an important property of a material which determines its ability to become elongated due to the application of stress.

Mathematically, the ductility of a material can be expressed as percentage elongation in length:

$\% el = \frac{\Delta L}{L_i} =\frac{L_f - L_i}{L_i}$
