High intensity sounds are perceived as relatively loud sounds. The sound waves which are most intense and perceived as loud sounds are those which have a ______ . Identify the one characteristic which is unique of such sound waves.

Answers

Explanation:

loud sound depends on amplitude, intensity, frequency and energy.

as already mention high intensity sounds are perceived as loud sounds.

and the intensity of the sound is the rate at which the energy through a cross sectional area of a medium. higher intensity means higher amplitude. if we put more energy as source means we providing higher amplitude vibrations to the particles which cause the increase in intensity result is louder sound.

How to find the period of a wave

Answers

The method to choose depends on what information you have, and
on what you can measure. Here are a few possible methods:

-- Measure the period. Start your clock when one peak
of the wave passes you. Stop the clock when the next
peak passes you. The time between the two peaks is
the wave's period.

-- Divide the wave's wavelength by its speed. That quotient
is the wave's period.

-- Use an electronic frequency meter to measure the wave's
frequency. Then take its reciprocal (divide ' 1 ' by it). The
result is the wave's period.

The conductive tissues of the upper leg can be modeled as a 40- cm-long, 12-cm-diameter cylinder of muscle and fat. The resistivities of muscle and fat are 13 Ω m and 25 Ω m, respectively. One person’s upper leg is 82% muscle, 18% fat. What current is measured if a 1.5 V potential difference is applied between the person’s hip and knee?

Answers

Answer:

current = 0.0027 A

Explanation:

the resistivity of upper leg

$\rho = 0.82 (13) + 0.18(25) = 15.16 ohm . m$

Resistance of upper leg

$R = (\rho L)/(A)$

$= (\rho L)/(\pi R^2)$

$= (15.16 * 0.40)/(\pi [(0.12)/(2)]^2)$

= 551.27 ohm

current $i = (V)/(R)$

$current = (1.5)/(551.27)$

current = 0.0027 A

What is the highest degrees above the horizon the moon ever gets during the year in the Yakima Valley ?

Answers

The trickiest part of this problem was making sure where the Yakima Valley is.
OK so it's generally around the city of the same name in Washington State.

Just for a place to work with, I picked the Yakima Valley Junior College, at the
corner of W Nob Hill Blvd and S16th Ave in Yakima. The latitude in the middle
of that intersection is 46.585° North. That's the number we need.

Here's how I would do it:

-- The altitude of the due-south point on the celestial equator is always
(90° - latitude), no matter what the date or time of day.

-- The highest above the celestial equator that the ecliptic ever gets
is about 23.5°.

-- The mean inclination of the moon's orbit to the ecliptic is 5.14°, so
that's the highest above the ecliptic that the moon can ever appear
in the sky.

This sets the limit of the highest in the sky that the moon can ever appear.

90° - 46.585° + 23.5° + 5.14° = 72.1° above the horizon .

That doesn't happen regularly. It would depend on everything coming
together at the same time ... the moon happens to be at the point in its
orbit that's 5.14° above ==> (the point on the ecliptic that's 23.5° above
the celestial equator).

Depending on the time of year, that can be any time of the day or night.

The most striking combination is at midnight, within a day or two of the
Winter solstice, when the moon happens to be full.

In general, the Full Moon closest to the Winter solstice is going to be
the moon highest in the sky. Then it's going to be somewhere near
67° above the horizon at midnight.
