1. Rocks found in a river bed would typically be what type of rocks?

1 answer:

8 0

<span>Igneous or metamorphic. Depending on the energy of the river, they could be anything from large, rounded cobbles or pebbles (as per classification of the Udden-Wentworth Scale), or sand and gravel as identified under other systems. Or angular clasts that haven't been rounded by moving along the bed. Note that the Udden-Wentworth is usually applied to sedimentary features, but can also be used in classifying the *size* of any rock. </span>

At what depth(km) would a rock experience temperature of 5500C?

kow [346]

Explanation:

A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.

But let us use the earth's geothermal gradient to solve this problem.

The geothermal gradient is the rate at which temperature is increasing with depth.

The geothermal gradient 25°C/km

At 5500°C,

5500°C x $\frac{1}{25}$ $\frac{k}{C}$ = 220km

But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).

The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.

5. Some undiluted acids are more corrosive when diluted

wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
