What is the third harmonic
frequency that it produces?
(Speed of sound = 343 m/s)
(Unit = Hz)
please help me guys will give brainliest and lots of points
Answers
Answer: The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency.
Explanation: Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.

While at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 23 s.A. What is your speed?
B. What is the magnitude of your acceleration?
C. What is the ratio of your weight at the top of the ride to yourweight while standing on the ground?
D. What is the ratio of your weight at the bottom of the ride toyour weight while standing on the ground?
Answers
Answer:
Explanation:
From the given information:
radius = 15 m
Time T = 23 s
a) Speed (v) = [tex]\dfrac{2 \pi r}{T}[/tex]
[tex]v = \dfrac{2\times \pi \times 15}{23}[/tex]
v = 4.10 m/s
b) The magnitude of the acceleration is:
[tex]a = \dfrac{v^2}{r} \\ \\ a = \dfrac{(4.10)^2}{15}[/tex]
a = 1.12 m/s²
c) True weight = mg
Apparent weight = normal force
From the top;
the normal force = upward direction,
weight is downward as well as the acceleration.
true weight - normal force = ma
apparent weight =mg - ma
[tex]\dfrac{apparent \ weight}{true \ weight} = \dfrac{(mg - ma)}{(mg)}[/tex]
[tex]=1- \dfrac{1.12}{9.8}[/tex]
= 0.886 m/s²
d)
From the bottom;
acceleration is upward, so:
apparent weight - true weight = ma
apparent weight = true weight + ma
[tex]\dfrac{apparent \ weight }{true \ weight} =\dfrac{ mg + ma}{mg}[/tex]
[tex]\dfrac{apparent \ weight }{true \ weight} =1+ \dfrac{a}{g} \\ \\ = 1 + \dfrac{1.12}{9.8}[/tex]
[tex]= 1 + \dfrac{1.12}{9.8} \\ \\[/tex]
= 1.114 m/s²

Electromagnets are an example of how electricity can create magnetism is True statement.
What is Electromagnet?Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.
The coils stop functioning as a magnet when the electricity is turned off. When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.
They both make use of electromagnets, which use electricity to apply a magnetic field. Extremely strong electromagnets are used by wrecking yards to transfer heavy scrap metal or even entire cars from one location to another.
Therefore, Electromagnets are an example of how electricity can create magnetism is True statement.

Answer:

Explanation:
ohm found that current, voltage, and resistance in a circuit are always related in the same day.
ohms obersivations
ohms found that if the factors that affect resistance are held constant, the resistance of most conductors does not depend on the voltage across them charging the voltage in a circuit changes the current but does not change the resistance regardless of the applied voltage. the ohms law resistance in a circuit is equal to voltage divided by current
resistance =current or voltage =current × resistance
The speed of light in air is 3.00 x 10^8 m/s. If a light wave has a wavelength of 5.80 x 10^-7m, what is its frequency?
Answers
Answer:
5.17 x 10^14 1/s
Explanation:
Equation:
c = λ f
c = speed of light
λ = wavelength
f = frequency
Solve:
3.00 x 10^8 m/s = (5.80 x 10^-7m) * f
f = (3.00 x 10^8 m/s) / (5.80 x 10^-7m)
f = 5.17 x 10^14 1/s

If a sound wave has a wavelength of 0.790 meters, and is travelling at a speed of 355 m/s, what is the period of oscillation for this wave?
Answers
Time a.k.a period = 1/frequency
Step 1: solve for frequency using the first equation
0.79m = 355/frequency
Frequency=280.45 Hz
Step 2: solve the period using the second equation
1/280.45 = 0.00357=3.57*10^-3 seconds
A boundary with a small opening. There is a vector straight from the opening labeled D and an angle labeled theta to another ray, both striking a surface with a red point.
