what is the fundamental frequency in hz of a string that has a length of 1 m and a wave speed of 45 m/s?
It is possible to determine that the string's fundamental frequency will be 45 Hz using basic harmonic motion.
The length of the string affects the standing wave's wavelength for each harmonic. Taking into account that the string's length and wavelength are the same It implies that the length of the string is equal to one wavelength. Answers would vary if more wavelengths were produced. The wavelength is therefore 1 m. 45 m/s for the wave speed. As can be seen from basic harmonic motion, Speed x Wavelength = Frequency, recurrence = 45/1, and frequency is 45 hertz. As a result, the string's frequency is 45 Hz. Over the length of the guitar string, there will be 3/2 wavelengths at the third harmonic. In other words, L = (3/2) where L is the length of a guitar string and is the wavelength.

Two notes with frequencies of 66 and 70 Hz are sounded together. The resulting beat frequency is
By deducting the higher frequency (70 Hz) from the lower frequency (66 Hz), the beat frequency, which is 4 Hz, can be computed.
When two notes with slightly different frequencies are sounded together, they create a beat frequency, which is the difference between the two frequencies. In this case, the beat frequency can be calculated by subtracting the lower frequency (66 Hz) from the higher frequency (70 Hz), which results in a beat frequency of 4 Hz.
This means that the two notes are interfering with each other, creating four beats per second.
These beats are audible and can be heard as a pulsating sound, which is the beat frequency. The speed of the beats depends on the difference between the two frequencies, and the closer the frequencies are, the slower the beats will be. This phenomenon is used in tuning musical instruments to achieve perfect harmony and eliminate dissonance.

The volume per second of a fluid flowing through a horizontal pipe of length l is given by kpa/n where k is constant, p is the excess pressure (force per unit area) a is the radius of the pipe and U is the frictional quantity of dimension MLT-1 by dimensions find the number x
According to the given statement the number x is 2. The number x represents the dimensions of the term p * a in the given equation.
By comparing the dimensions of both sides of the equation, we find that x is equal to 2.
The equation given is:
Volume per second = k * (p * a) / n
Where:
- k is a constant
- p is the excess pressure (force per unit area)
- a is the radius of the pipe
- n is the frictional quantity of dimension MLT⁻¹
To find the number x, we need to determine the dimensions of each term in the equation.
1. Dimension of Volume per second:
- Volume has the dimension L³ (length cubed)
- Time has the dimension T (time)
- Therefore, Volume per second has the dimension L³ / T
2. Dimension of k:
- The equation states that k is a constant. Constants are dimensionless.
3. Dimension of p * a:
- Pressure has the dimension M / (L * T² ) (mass divided by length and time squared)
- Radius has the dimension L (length)
- Multiplying pressure by radius results in the dimension M / (L * T² ) * L = M / (L² * T² )
4. Dimension of n:
- Given in the question, n has the dimension MLT⁻¹
(mass times length times time to the power of -1)
Now, we can equate the dimensions:
L³ / T = k * (M / (L² * T² )) * MLT⁻¹
Simplifying the dimensions:
L³ / T = k * M / (L² * T² ) * MLT⁻¹
L³ / T = k * M / L² * M / T² * L^-1 * T⁻¹
L³ / T = k * M² / L² * T⁻¹
To equate the dimensions, both sides of the equation must have the same dimensions. Therefore:
L³ / T = k * M² / L² * T⁻¹
Comparing the dimensions on both sides, we can conclude:
L³ / T = k * M² / L²* T⁻¹
The dimensions on the left side are L^3 / T, and the dimensions on the right side are (k * M²) / (L² * T).
Therefore, the number x is 2.
The number x represents the dimensions of the term p * a in the given equation.
By comparing the dimensions of both sides of the equation, we find that x is equal to 2.

Un delfín nada en el mar, a una profundidad tal que experimenta es de 2,22 x 10⁵ PA. Si la densidad del agua del mar es de 1030kg/m³, ¿A qué profundidad nada el delfín?
Answer:
El delfín nada a una profundidad de 22 m
Explanation:
El principio fundamental de la hidrostática establece que la presión en un punto del interior de un fluido (presión hidrostática) es directamente proporcional a su densidad, a la profundidad que se encuentre dicho punto y a la gravedad del sitio en el que se encuentre el fluido.
Esto se expresa como:
P=ρ⋅g⋅h

P es la presión en un punto del fluido. ρ es la densidad del fluido .g es la gravedad del lugar donde se encuentre el fluido. h es la profundidad.En este caso:
P= 2.22*10⁵ Paρ= 1,030 \(\frac{kg}{m^{3} }\)g= 9.8 \(\frac{m}{s^{2} }\)h= ?Reemplazando:
2.22*10⁵ Pa= 1,030 \(\frac{kg}{m^{3} }\) * 9.8 \(\frac{m}{s^{2} }\) * h
Resolviendo:
\(h=\frac{2.22*10^{5} Pa}{1,030\frac{kg}{m^{3} }*9.8 \frac{m}{s^{2} }}\)
h= 21.993 m ≅ 22 m

Students run an experiment to determine the rotational inertia of a large spherically shaped object around its center. Through experimental data, the students determine that the mass of the object is distributed radially. They determine that the radius of the object as a function of its mass is given by the equation r=km^2, where k=3m/kg^2. Which of the following is a correct expression for the rotational inertia of the object?
a) m^3
b) 1.8 m^5
c) 3.6 m^5
d) 6 m^5
e) 9 m^5
The correct expression for the rotational inertia of the spherically shaped object is \(\(\text{c) } 3.6m^5\)\).
In the given scenario, the students determine that the radius of the object is given by \(\(r = km^2\) with \(k = 3\, \text{m/kg}^2\)\). To calculate the rotational inertia of the object, we need to use the formula for rotational inertia of a spherical object, which is given by \(\(I = \frac{2}{5}mr^2\)\), where m is the mass of the object and r is the radius.
Substituting the given expression for r in terms of m, we have \(\(I = \frac{2}{5}m(km^2)^2\)\). Simplifying this equation, we get \(\(I = \frac{2}{5}mk^2m^4\)\).
Substituting the value of \(\(k = 3\, \text{m/kg}^2\)\), we have \(\(I = \frac{2}{5}(3\, \text{m/kg}^2)^2m^5\)\), which further simplifies to \(\(I = \frac{2}{5} \times 9 \, \text{m}^2/\text{kg}^2 \times m^5\)\).
Finally, multiplying the constants, we get \(\(I = 3.6 \, \text{m}^2/\text{kg}^2 \times m^5\)\), which corresponds to option c) \(3.6 \(m^5\)\).
Therefore, the correct expression for the rotational inertia of the object is \(3.6 \(m^5\)\).

How deep is the floor of the ocean if a sonar sound takes 7 seconds to return back to the ship?
what kind of plate boundary is found where the caribbean and north american meet
The kind of plate boundary found where the Caribbean and North American meet is a transform plate boundary.
This is due to the way that the North American and Caribbean tectonic plates move in relation to one another. The North American Plate moves in a westerly direction, while the Caribbean Plate moves in an easterly direction. The boundary where they meet is characterized by a significant amount of seismic activity, as the two plates move and grind against each other. This movement results in the formation of a fault line, known as the North American-Caribbean Plate Boundary, which extends from the eastern edge of the Caribbean Plate to the northern coast of South America.
Transform plate boundaries occur where two tectonic plates slide past one another in opposite directions. This is in contrast to convergent boundaries, where two plates move towards one another, or divergent boundaries, where two plates move away from each other. At transform boundaries, the movement of the plates is characterized by a significant amount of friction, as the two plates rub against each other. This can cause earthquakes and other geological activity in the region.
The North American-Caribbean Plate Boundary is a particularly important transform boundary, due to its location in the Caribbean Sea. The boundary extends for around 5000 kilometers, from the eastern edge of the Caribbean Plate to the northern coast of South America. It is one of the most seismically active regions in the world, due to the constant movement of the two tectonic plates. The Caribbean Plate is moving eastward at a rate of around 2 cm per year, while the North American Plate is moving westward at around the same rate.
In conclusion, the kind of plate boundary found where the Caribbean and North American meet is a transform plate boundary. This boundary is characterized by the movement of two tectonic plates in opposite directions, resulting in a significant amount of seismic activity in the region. The North American-Caribbean Plate Boundary is one of the most seismically active regions in the world, due to the constant movement of the two plates.
