:
1. The question is whether a similarly high ion density
would have existed on the axis when the pencil beam is
switched off.
2. The value of the surface energy would therefore be
expected to depend on crack velocity.
3. If the entire Earth were covered by ocean, high and
low tides would follow one another at regular intervals in
response to the rotation of the Earth and the revolution of
the Moon.
4. The kinetic theory and the corresponding molecular
theory of liquids and gases have been of great service in
helping to form mental pictures of many processes which
would be otherwise too difficult to understand.
5. The average depth of the ocean is approximately 13000
feet. This figure seems large, but if we were to build a scale model with the Earth as a ball 100 feet in diameter, this ocean would be less than half an inch deep.
6. For example, if the magnitude and phase of the negative resistance generator input impedance were largely dependent on transistor transconductance, the conversion of low-frequency noise variation in transconductance to signal amplitude and phase modulation in the Q multiplied resonator would result in unacceptable performance.

, should would:
1. It is essential you should know that this solution fumes
slightly in air.
2. It should be emphasized that amorphous sulphur does
not crystallize at all.
3. One should always dilute sulphuric acid by pouring it
into a large excess of water.
4. The preparation of highly purified tellurium requires
that more time and labour should be spent than is the case
with sulphur and selenium.
5. From the requirements of the theory of Bohr it is to
be anticipated that the theory would be more accurate the
higher the speed of the particle.
6. If the entire Earth were covered by ocean, high and
low tides would follow one another at regular intervals in
response to the rotation of the Earth and the revolution of
the Moon.

7. Formerly weather forecasts would base almost
exclusively on data secured from the air close to the Earth.
8. In the absence of dust the air would become
supersaturated with water and clouds and rain would be
unlikely to form.
9. It is natural that aluminium should receive a great
amount of attention from research workers with a view to
improving the mechanical properties of the metal.
10. The kinetic theory and the corresponding molecular
theory of liquids and gases have been of great service in helping to form mental pictures of many processes which would be otherwise too difficult to understand.

2. Of course the ancients did not know why amber could
attract the light objects.
3. This substance might be an insulator or a conductor.
4. Let us picture what ought to happen provided there
were a conducting wire between two points of unequal
potential.
5. From the reservoir the water was directed through a
channel to some point where it could fall through steel pipes.
6. In order that the compound might be used it had to
be purified.
7. However that might be, the repair was ordered to be
exec u ted.
8. Important as this question may be in itself, the debate
on the subject went far beyond its original bounds.
