A closed-end organ pipe is used to produce a mixture of sounds. The third and fifth harmonics in the mixture have frequencies of 1100 Hz and 1833 Hz respectively. What is the frequency of the first harmonic played by the organ pipe
Answers
Answer:
[tex]F_1=366.67Hz[/tex]
Explanation:
From the question we are told that:
Frequency of 3rd harmonics [tex]F_3=1100[/tex]
Frequency of 5th harmonics [tex]F_3=1833[/tex]
Generally the equation for Wavelength at 3rd Harmonics is mathematically given by
[tex]\lambda_3=\frac{4}{3}l[/tex]
Therefore
[tex]F_3=\frac{3v}{4l}[/tex]
Generally the equation for Wavelength at 1st Harmonics is mathematically given by
[tex]\lambda_1=\frac{4}{1}l[/tex]
Therefore
[tex]F_1=\frac{v}{4l}[/tex]
Generally the equation for the frequency of the first harmonic is mathematically given by
[tex]F_1=\frac{F_3}{3}[/tex]
[tex]F_1=\frac{1100}{3}[/tex]
[tex]F_1=366.67Hz[/tex]
The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
Answers
Answer: hello your question is incomplete below is the complete question
answer : Angular acceleration = 7.88 rad/s^2 ( clockwise )
minimum coefficient of friction = -0.2225
Explanation:
First step : we calculate acceleration at point O
a = rα
acceleration at point A
aA = ( 2r ) α = 2α
∑Fy ( force in y axis ) = mass of block * aA
∴ T = mBlock ( g - 2α )
= 8.7 ( 9.81 - 2α )

Blue light and ultraviolet light are both shown upon a surface of sodium and cause the ejection of electrons. Which light will cause the ejected electrons to have a higher kinetic energy
Answers
Answer:
ultraviolet light (UV) has more energy than blue light, so electrons must have higher kinetic energy
Explanation:
This is a photoelectric effect exercise, which was explained by Einstein assuming that light is composed of photons and that they interact with electrons as particles.
h f = K + Ф
where fi is the work function of the material
K = hf -Ф
the work function for a given material is constant, therefore let's find the energy of each photon
E = h f
c = λ f
f = c /λ
we substitute
E = h c /λ
Blue light λ = 450 nm = 450 10⁻⁹ m
E = 6.63 10⁻³⁴ 3 10⁸/450 10⁻⁹
E = 4.42 10⁻¹⁹ J
UV light λ = 400 nm = 400 10⁻⁹ m
E = 6.63 10⁻³⁴ 3 10⁸/400 10⁻⁹
E = 4.97 10⁻¹⁹ J
therefore ultraviolet light has more energy than blue light, so electrons must have higher kinetic energy
A football team is practicing outdoors in August. The temperature is 94ºF, and the relative humidity is 80 percent. What steps must the coach take to prevent heat-related illness in his players on this day?
Answers
Answer:
To prevent heat-related illness in the players the coach could provide cooling off-breaks that allow players to cool off, have cool water, and fan themselves.
The coach can schedule training schedules at more pleasant temperatures such as in the morning (before 10am), late afternoon (after 5pm) or at night. In addition, he should make sure athletes keep their hydration up, always drinking water. Lastly, the coach should indicate that players wear light clothing with fabric that releases sweat. Also, all players should wear sunscreen as well.

Answers
Answer: 29.48 s
Explanation:
Given
The initial height of the ball is [tex]h=2.6\ m[/tex]
The ball leaves with an initial velocity of [tex]u=-20\ m/s[/tex]
Using the equation of motion
[tex]h=ut+\dfrac{1}{2}at^2\\\text{Insert the values}\\\\2.6=20\cdot t+\dfrac{1}{2}\times 9.8\times t^2\\\\\Rightarrow 9.8t^2+20t-5.2\\\\\Rightarrow t=\dfrac{-20\pm \sqrt{20^2-4\times 9.8\times (-5.2)}}{2\times 9.8}\\\\\Rightarrow t=\dfrac{-20\pm 603.84}{19.8}\\\\\Rightarrow t=29.48\ s\quad [\text{Neglecting negative t}][/tex]
Therefore, it take 29.48 s for ball to reach the ground.
Two particles experience an attractive electric force of 5 N. If one of the charges triples and
the distance between them doubles, what is the new electric force?
Answers
3.75 N
Explanation:
F = k(q)(q)/r^2 = 5 N
F' = k(q)(3q)/(2r)^2
= k×3(q)(q)/4r^2
= (3/4)[k(q)(q)/r^2]
= (3/4)F
= (3/4)(5 N)
= 3.75 N
The new electric force is 3.75 N.
The force on the charges by Coulomb's law is given by;
F = kq1q2/r^2
where q1=q2
F = kq1^2/r^2
Where F = 5N
If one of the charges triples;
q2 = 3q1
distance doubles = r = 2r
F' = 3kq1^2/4r^2
So;
F' = 3/4 F
F' = 3/4 × 5 = 3.75 N
The new electric force is 3.75 N.

A capacitor has plates of area 5.25 * 10 ^ - 5 * m ^ 2 which are separated by 3.14 * 10 ^ - 6 * m . What is its capacitance?
Answers
Answer:
1.47 x 10^-10
Explanation:
Acellus
The capacitance of the given capacitor is approximately 1.4805 × [tex]10^{(-10)[/tex]F.
The capacitance (C) of a capacitor is determined by the formula:
C = (ε₀ ×A) / d
Where:
C is the capacitance
ε₀ is the permittivity of free space (ε₀ ≈ 8.85 × [tex]10^{(-12)[/tex] F/m)
A is the area of the plates
d is the distance between the plates
Given:
Area of the plates (A) = 5.25 × [tex]10^{(-5)[/tex]m²
Distance between the plates (d) = 3.14 × [tex]10^{(-6)[/tex] m
Using the given values, we can calculate the capacitance:
C = (ε₀ ×A) / d
C = (8.85 × [tex]10^{(-12)[/tex] F/m) × (5.25 × [tex]10^{(-5)[/tex] m²) / (3.14 × [tex]10^{(-6)[/tex]m)
Simplifying the expression:
C = (8.85 × 5.25 × [tex]10^{(-12 - 5)[/tex]) / (3.14 × [tex]10^{(-6)[/tex])
C = (46.4625 × [tex]10^{(-17)[/tex]) / (3.14 × [tex]10^{(-6)[/tex])
C = 14.805 × [tex]10^{(-17 - (-6)}[/tex])
C = 14.805 × [tex]10^{(-11)[/tex]
Using scientific notation, capacitance as:
C = 1.4805 × [tex]10^{(-10)[/tex] F
Therefore, the capacitance of the given capacitor is approximately 1.4805 × [tex]10^{(-10)[/tex] F.

When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model. Why not
Answers
Answer:
When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model because the Catholic Church, which was the power at the time, stated it was false, and anybody who believed Copernicus and spread the "myth" were excommunicated or even executed. This was because a sun centered universe would mean that everything the Catholic Church had been teaching about how the Earth was the center of the universe would be false. If people believed it, the church would no longer be seen as the infallible authority, so they needed to stop it from spreading.

A Star fleet science officer drops a large rock from a height of 1.55 m onto the surface of an alien planet. The rock strikes the ground in 0.230 s. Determine the acceleration of gravity.
Answers
Answer:
58.6 m/s²
Explanation:
Applying,
s = ut+gt²/2............ equation 1
Where s = height of the rock, u = initial velocity, t = time, g = accelration due to gravity of the planet.
From the question,
Given: s = 1.55 m, t = 0.23 s, u = 0 m/s (dropped from an height)
Substitute these values into equation 1
1.55 = (0×0.23)+g(0.23²)/2
1.55 = 0.0529g/2
0.0529g = 3.1
g = 3.1/0.0529
g = 58.6 m/s²

How much farther away from a current-carrying wire would you
have to stand in order for the magnetic field generated by the
wire to be half as strong?
Answers
Answer: Your question is open ended therefore i will provide a general answer based on the general concept of your question.
Answer : At half distance between the center of the Magnetic field the magnetic pole the effect of the magnetic field generated will be half as strong
Explanation:
Magnetic force ∝ 1 / d^2
This simply means increase in the squared distance of an object leads to the decrease in the effect of the magnetic field generated by a current carrying wire.
Hence ;
At half distance between the center of the Magnetic field the magnetic pole, the effect of the magnetic field generated will be half as strong
Half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.
What is magnetic field?The magnetic field is the field in the space and around the magnet in which the magnetic field can be fill.
The value of magnetic field is reduced from a wire, with the distance of the wire.
The magnetic field is inversely proportional to the square of the distance of the current-carrying wire.
Hence, half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.
