what is the definition of the word amplitude
Explanation:
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
Two by four about a three the espn by the Xbox 360 by the one two three and the logical by the fire the iso cohedron uh the Isosceles and the diameter by the three by four?
Answer:
divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4
Explanation:
So the first few words in this statement talks about two and four being equal to around three therefore giving you "divided by 2" as you need to divide the four by 2 and add one to get 3. The next statement "the espn by the Xbox 360", espn can be deemed as a secured entity that paces around a nun therefore giving you entity_secured_pace_nun and since this is being multiplied by a box and by 360, you apply the "Improve Rule of Baseless Base". This rule allows you to get entity_secured_pace_nun_box_9. Box comes from multiplying what we have with box and the 9 comes from adding 3+6+0. Since a logical fire is present in this equation, you burn the letters in "two three" that have no protection, these letters are t,w,t,h, and r. Next, you can take cohedron that sounds like couldron and brew yourself an akward potion with the tri sided isosceles. The diameter can be seen as a round up rule that allows you to regroup the answer you have so far. The "by the three by four" can easily be translate from the "Baseless Base Rule Compilation" giving you divided by 3 and divided by 4. That is why the answer is divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4. No need to thank me.

Answer:
Your education back ground
A high fountain of water is located at the center of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 15m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55°. How high is the fountain?
Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2[tex]\pi[/tex]r
where C is the circumference and r its radius.
r = [tex]\frac{C}{2\pi }[/tex]
= [tex]\frac{15}{2(\frac{22}{7}) }[/tex]
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 55 = [tex]\frac{h}{2.4}[/tex]
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.

A ball has 17 J of kinetic energy and its mechanical is 25 J
If the ball has a mass of 3.2 KG what is it’s height above ground?
Answer:
0.255m
Explanation:
The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.
What is kinetic energy ?Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.
The sum of kinetic and potential energy of the object is called its mechanical energy.
given Ke of the ball = 17 J
mechanical energy = 25 J
then potential energy = 25 J - 17 J = 8 J.
We have the relation between potential energy, mass and height h as :
p = mgh .
given the mass m = 3.2 kg
g = 9.8 m/s²
then, h = p / (mg)
h = 8 J / (3.2 kg× 9.8 m/s² )
= 0.25 m.
Therefore, the height of the ball above the ground is 0.25 m.

a. 7,500 m
b. 1,505 m
c. 300 m
d. 1,495 m
2. Humans can hear thunder at different frequencies. These correspond to wavelengths ranging from 2.75 to 16.5 meters. If the speed of sound is approximately 330 m/s, what frequencies of thunder can humans hear?
a. 2.75 to 16.5 hertz
b. 907.5 to 5,445 hertz
c. 20 to 120 hertz
d. 0.0083 to 0.05 hertz
3. Two similar waves X and Y travel through the same medium. Wave X has a frequency of 200 hertz and a wavelength of 35 meters. Wave Y has a frequency of 700 hertz. What is the wavelength for wave Y?
a. 4,900,000 meters
b. 122.5 meters
c. 0.1 meter
d. 10 meters
4. California sea lions communicate underwater at frequencies ranging from 500 to 4,000 hertz. The speed of sound in sea water is approximately 1,500 m/s. What are the approximate wavelengths of sound with which the California sea lions communicate?
a. 750,000 to 6,000,000 meters
b. 0.375 to 3 meters
c. 2,000 to 5,500 meters
d. 0.33 to 2.66 meters
With the use of wave speed formula, below are the answers to the questions
1. C
2. C
3. D
4. B
All the question centered on wave speed, wavelength and wave frequency. The relationship between these three quantities is;
wave speed = wavelength x frequency
That is,
V = Fλ
1. The given parameters are;
V = 1,500 m/s
F = 5 Hz
wavelength λ = V/F = 1500/5 = 300 m
2.) Given that the wavelengths ranging from 2.75 to 16.5 meters and the speed of sound is approximately 330 m/s
When wavelength = 2.75 m
F = V/ λ = 330 / 2.75 = 120 Hz
When wavelength = 16.5 m
F = V/ λ = 330 / 16.5 = 20 Hz
Therefore, the frequencies of thunder humans hear ranges from 20 Hz to 120 Hz
3.) Since the two waves are similar, they will be travelling at the same speed. That is,
Wave speed of X = Wave speed of Y
For wave X and Y respectively;
F = 200 Hz and 700 Hz
λ = 35 m and λm
Find λ of Y by equating the two wave speed. That is,
Fλ for X = Fλ for Y
200 x 35 = 700 λ
λ = (200 x 35)/ 700
λ = 7000 / 700
λ = 10 m
Therefore, The wavelength for wave Y is 10 m
4.) Given that the sea lions frequencies are ranging from 500 to 4,000 hertz. And the speed of sound in sea water is approximately 1,500 m/s
By using the same formula,
V = Fλ
Make wavelength the subject of formula
λ = V / F
When F = 500 Hz
λ = 1500/500 = 3 m
When F = 4000 Hz
λ = 1500/4000 = 0.375 m
Therefore, the approximate wavelengths of sound with which the California sea lions communicate is of the range 0.375 m to 3 m
