Answer:

Exolaiend in explanation section

Explanation:

First of all, the automatic hammer is used to drive nails into tight spaces where where we can't get a sufficient striking force if we are to use a normal regular hammer in driving the nail.

So the nail to be driven is lifted out of rest(it's position). The energy here is gravitational potential energy.

Now, when it is driven into the tight spaces, the gravitational energy would be converted to kinetic energy due to the motion and speed involved.

Answer:

The validation of seafloor spreading in the 1950s and 60s

Explanation:

The theory of seafloor spreading was supported by numerous evidence including thermal probes that showed that heat flow over the mid-ocean ridges measured up to four times those measured in general bottom sediments, which are taken as due to the presence of molten Earth material close to the ridge crest

The ridge crest also show signs unusually seismic wave velocities that are considered to be due to microfracturing and thermal expansion from upwelling magma

Choose the term that best fits the following definition: the liquid or gas that carries the sample across the solid support.

iren [92.7K]

The correct answer is option B.

The liquid or gas that carries the sample across the solid support is called mobile phase.

In chromatography, there are two phases: mobile phase and solid phase.

The mobile phase can be either in gas form or liquid form.

While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.

In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.

on the other hand, stationary phase is motionless.

The sulfuric acid–catalyzed reaction of isopentyl alcohol with acetic acid to form isopentyl acetate is performed. This reaction

murzikaleks [220]

Answer:

The correct option is acetic acid

Explanation:

Distillation is the process of separating a mixture of substances based on differences in boiling points. During distillation, the compound with the lowest/least boiling point is distilled and collected first and then the one with the next least boiling point and it goes on like that.

From the explanation above, <u>acetic acid has the least boiling point (in the organic layer) with 118°C and thus will distill first</u>. This is then followed by isopentyl alcohol (130°C) and then isopentyl acetate (142°C) and finally sulfuric acid water (290°C).
