How much time would it take to distribute one avagadro's number of wheat grains if 10^10 grains are A)1.9*10^2 years B)1.9*10^10
Makovka662 [10]

Answer:

It takes  1.9 \times 10^{6} years to distribute all the grains.

Explanation:

In one second, 10^{10} grains of wheat are distributed.

We are supposed to find the time it would take to Distribute Avogadro number of grains.

1 avogadro number = 6.022 \times 10^{23}

Number of grains distributed in 1 day = 86400 \times 10^{10}

                                                             = 8.64 \times 10^{14}

Number of grains distributed in 1 year= 8.64 \times 10^{14} \times 365

                                 = 3.1536 \times 10^{17}

Time taken = \frac{Number of grains to be distributed}{grains distributed in 1 year}

            = \frac {6.022 \times 10^{23}}{3.1536\times 10^{17}}

            = 1.9 \times 10^{6}

Eventually, everyone must sleep due to our (1 point) need for mental rest. beta waves. biological rhythms. delta waves.
Bad White [126]
Out of the available answers, the most likely correct would be that eventually everyone must sleep due to our need for mental rest. However, it is not as simple as this, as all of the processes implicated with mental rest (including the restoration of biological rhythms as mentioned in an alternative answer) cannot necessarily be summed up in this way.

Which process results in the formation of sedimentary rocks?
klio [65]

Answer:

A. Rock fragments are layered and pressurized over time.

Explanation:

Sedimentary rocks are derived from pre-existing rocks that have been subjected to agents of denudation, weathered, transported and deposited within a basin.

In the basin, the sediments are accumulated in their final resting position.

  • Sediments are accumulated as layers on top of one another.
  • The pressure of the sediment on top of another forces out water and presses the layers into sheets.
  • Over time, the compression leads to lithification of the rock.
  • During lithification, compaction and cementation occurs.
