Answer:
Increase the amplitude
Explanation:
The energy conveyed by a wave is directly proportional to the square of its amplitude. Thus; E ∝ A²
This means that increasing the amplitude will lead to an increase in the energy.
Now, the amplitude of a wave is the height of a wave from it's highest point known as the peak, to the lowest point on the wave known as the trough whereas wavelength refers to the length of a wave from one peak to the next.
This means that increasing the amplitude has no effect on the wavelength.

Answer:
linear speed = 595.706 miles/hours
Explanation:
to find the linear speed of the moon (Express your answer in miles per hour)
Given
radius of the moon = 1737.1 km = 1079.4 mile (a constant value)
The mean distance of a moon from a planet is 2.82 * 10^ 5 miles
therefore, the total distance from the moon to the planet =
=1079.4 + 2.82 * 10^ 5 = 283,079.4 miles
Assuming that the orbit of the moon around the planet is circular and that
1 revolution takes 21.6 days = 21.6*22hours = 475.2 hours
(1 day is 22 hours),
therefore, the time taken for the moon to move round the planet is = 475.2 hours
then,
linear speed = Distance/time
=283,079.4 miles /475.2 hours = 595.706 miles/hours
Good luck ! I am a communications engineer, and I don't have a
nice easy answer for this one.
First of all, you put everything you can underground ... the power
and communications lines in and out of every cell tower.
Then you overbuild and double up on everything possible:
... You put enough batteries inside every cell site building to
operate the site after the commercial power fails.
... Add a rectifier plant to every site. That does nothing but keep
the batteries charged whenever the power is working.
... Add a generator to every site. It has to come on automatically
and re-charge the batteries if they run down while the power still
is not back on.
... Build every cell tower three times as strong as it has to be
for normal weather conditions, and twice as strong as it has to
be for high winds.
... Do the same thing for every antenna, on every cell tower,
at every cell site.
And remember: One cell tower only serves the cell phones that are
within a few miles from it. In a big city, there may be HUNDREDS of
cell towers. You have to do the same things to all of them.
