Answer:

A) The water should be well sealed by putting a water trap between the aspirator and the sublimator to avoid water backing up and filling the sublimator as a result of sudden pressure drop.

B) Variation in water pressure could cause water to back up and fill the sublimator.

A 3.0 pF capacitor consists of two parallel plates that have surface charge densities of 1.0 nC/mm2 . If the potential between t
Archy [21]

Answer:

A=81mm^2

Explanation:

We know that for a capacitor Q=CV, where <em>Q </em>is the charge of one plate, <em>C</em> the capacitance and <em>V</em> the potential between the plates.

We also know that Q=\sigma A, since \sigma is the surface charge density and <em>A</em> the area of the plate (both equal in our case).

Putting all together:

A=\frac{CV}{\sigma}

Which for our values is:

A=\frac{(3\times10^{-12}F)(27\times10^3V)}{1\times10^{-9}C/mm^2}=81mm^2

Where we notice that the S.I. units combination FV/C must not have units (we can verify it directly from their definitions or we notice that mm^2 is enough to describe an area).

In lecture, it was discussed measurements of mass, temperature, time, volume and length. which of these is not an si base unit (
photoshop1234 [79]

From the options provided in the question, the measurement which is not an SI base unit is volume.

<h3>What is SI base unit?</h3>

This is referred to as the standard and fundamental unit of measurement of various quantities or variables which is defined arbitrarily and not by combinations of other units.

Volume is a quantity which is derived from the combination of lengths in a  three-dimensional manner which is why the formula is length× breadth×height and the unit is cm³. This is gotten from the combination of the unit of length which is cm.

This is therefore the reason why volume was chosen as the most appropriate choice.
