Which best explains the relationship between parent rock and soil composition

1 answer:

8 0

Soil is the result of chemical or physical weathering of a parent rock .this is so since the soil is just tiny particle of the huge parent rock and hence it affects soil composition . if the parent rock was made of limestone then the soil composition will constitute calcite and aragonite mineral elements from the limestone parent rock.

The less internal heat a jovian planet emits the more it stirs up its clouds.

g100num [7]

The correct answer would be false. The less internal heat a jovian planet emits the lesser it stirs up its clouds making the atmosphere hotter. All of the four Jovian planets have unique atmospheres. They have more or less the same structures but they differ in their average temperature. As the distance of the planet is closer to the sun the atmosphere would be cooler. These planets are Jupiter, Saturn, Uranus and Neptune. They do not have a solid structure instead they are primarily composed of helium and hydrogen which makes them gas giants or ice planets. They are larger in size than the remaining planets in the solar system.

It takes a crane 59s to lift a flagstone using 342 W of power. How much work is done on the flagstone?

zepelin [54]

Answer: The work done on the flagstone is 20178 J

Explanation:

Power is the rate at which work is done . It is equal to the amount of work done divided by the time it takes to do the work.

$Work=Power\times time$

Given : work = ?

Power = 342 W = 342J/s

Time = 59 s

$Work=342J/s\times 59s=20178J$

Thus the work done on the flagstone is 20178 J

1. A heat engine operates between two reservoirs at T2 = 600 K and T1 = 350 K. It takes in 1.00 x 103 J of energy from the highe

Alex73 [517]

Answer:

$\Delta S_u=2.1429\ J.K^{-1}$

$W_c=416.67\ J$

Explanation:

Given:

temperature of source reservoir, $T_H=600\ K$

temperature of sink reservoir, $T_L=350\ K$

energy absorbed from the source, $Q_{in}=1000\ J$

work done, $W=250\ J$

Now change in entropy of the surrounding:

$\Delta S_u=\frac{dQ_L}{T_L}$

Since heat engine is a device that absorbs heat from a high temperature reservoir and does some work giving out heat in the universe as the byproduct.

$\Delta S_u=\frac{Q_H-W}{T_L}$
