One of the largest pipe organs is in the auditorium organ in the Fox Theatre. The pipe is 32 ft. Long and produces a sound with a wavelength of about 8.8m. If the speed of sound in air is 346 m/s what is the frequency of this sound? What is the period? Show all work and explain your answer.
Explanation:
length of pipe= 32 ft
wavelength of wave λ= 8.8 m
let f be frequency
we know velocity of wave v=λf
therefore, f=v/λ = 346/8.8 = 39.31 per second or hertz
time period = 1/f = 1/39.31 = 0.02543 seconds
The frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.
What is the frequency?Frequency is defined as the number of repetitions of waves occurring in 1 second. Frequency is also defined as the number of cycles completed in 1 second. SI unit of frequency is Hz.
The given data in the problem is;
L is the length of pipe= 32 ft
λ is the wavelength of wave= 8.8 m
f is the frequency=?
T is the time period=?
The frequency is fine as the ratio of the speed of wave and wavelength.,
[tex]\rm f= \frac{v}{\lambda} \\\\ \rm f= \frac{346}{8.8}\\\\ \rm f= 39.31 \ Hz[/tex]
The time period is guven as the inverse of the time period.
[tex]\rm T = \frac{1}{f} \\\\ \rm T = \frac{1}{39.31} \\\\ \rm T = 0.02543\ sec[/tex]
Hence the frequency of this sound will be 39.31-sec⁻¹or Hz. While the time period will be 0.02543 sec.

how does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?
Answer:
F' = 9F
Explanation:
The electric force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
It means,
[tex]F\propto \dfrac{1}{r^2}[/tex]
If distance decreased by a factor of 3, r' = r/3
Net force will become,
[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\dfrac{kq_1q_2}{r^2}\\\\=9\times F[/tex]
It means new force will become 9 times that of the initial force.

A Red-Tailed Hawk leaves its nest and flies 100.0 meters across the sky in 20 seconds, when it spots a garter snake on the ground below. It then flies 50.0 meters in 5.0 seconds to catch the snake. What was the hawk's average speed over his entire journey?
Answer:
7.5 m/s
Explanation:
A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs
Speed 1= distance/time
= 100/20
= 5m/s
When it spots a garter snake on the ground it flies 50 meters in 5 secs
Average speed= distance /time
= 50/5
= 10 m/s
Therefore the average speed of the hawk over the entire journey can be calculated as follows
= 10+5/2
= 15/2
= 7.5 m/s

Kathy had a heavy metal ball and Rich had a light wooden ball they drop the balls from the same height. they were surprised to discover that the two balls reach the ground at the same time. this is what they said after the balls landed select who you agree with. Kathy said ""the force of gravity must be acting the same on both balls."" Rich said ""I don’t agree the metal ball weighs more so the force of gravity is more on the heavier ball.""explain why you agree with who you choose
Answer: I scored a 9/10
Explanation:
I agree with Kathy gravity must be acting the same on both balls just because one ball is heavier doesn’t mean they will hit different times if the wooden ball was drop closer to the ground then the wooden ball would hit the ground first

How much resistance allows 6V battery to produce a current of 0.006 amps?
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms
From the Question we are told
How much resistance allows 6V battery to produce a current of 0.006 amps?
Generally the equation for Resistance mathematically given as
[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]
R=1000 ohms

Clara's grandfather is a captain of a cargo ship. He prefers to navigate his ship through the moderate neap tides. At these times, the line between Earth and the sun is at a right angle to the line between Earth and the moon. Which phase or phases of the moon describe this alignment?
Answer:
The phases are the first and third quarters.
Explanation:
During the first quarter of the moon phases, the line between Earth and the Sun is at a right angle to the line between Earth and the moon. At this time the moon has completed the first quarter of its orbit around the earth. At this point, half of the moon is fully reflecting light from the sun.
Also during the third quarter which is the last quarter, the line between the earth and the sun is at a right angle to the line between the earth and the moon. This is the time when the second half of the moon which was not illuminated during the first quarter becomes completely illuminated.

F = m x a. A ball of mass 0.35kg rolls on a smooth surface hits another object at rest and of mass 7kg. The second object gets an acceleration of 1.5m/s2. What acceleration does the ball get? Use newton’s third law.
Please show the working and thankyouu!!
Answer:
The acceleration the ball gets = 30 m/s²
Explanation:
The given parameters are;
The mass of the first ball that hits an object, m₁ = 0.35 kg
The mass of the object hit by the ball, m₂ = 7 kg
The acceleration given to the second object, a₂ = 1.5 m/s²
Let the a₁ represent the acceleration the ball gets
Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;
Therefore, we have;
The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N
The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁
By Newton's third law, F₁ = F₂, which gives;
m₁ × a₁ = m₂ × a₂
0.35 × a₁ = 10.5
a₁ = 10.5/0.35 = 30
The acceleration the ball gets = a₁ = 30 m/s².

Explanation:
i just did it on ap3x :)
The resistance of a wire which is used to power clothes dryer rank third as the area and diameter of wire is inversely proportional to the resistance of the wire. Thus, the correct option is A.
What is Electrical resistance?Electrical resistance is a measure of the opposition or friction to the current flow in an electrical circuit. Resistance is measured in the unit of ohms, that is symbolized by omega (Ω). Resistance of an electrical wire can be calculated by the formula:
R = (ρ×L)/A
where, R = Resistance of the wire,
ρ = Resistivity or specific resistance,
L = length of the electrical length,
A = Cross-sectional area of the electrical wire.
The resistance of a electrical conductor is dependent on the following factors including the cross-sectional area of the conductor, length of the conductor and the material of the electrical conductor.
Therefore, the correct option is A.

In calisthenics, the resistance is ultimately provided by __________. A. free weights B. springs and elastic bands C. gravity D. weight machines
When practicing calisthenics, the athlete's body is the only element that offers resistance. Thus, the resistance is ultimately provided by _gravity_. Option C is correct.
---------------------
Calisthenic is a physical discipline that is based only on the use of body weight.
It is a training system with physical activities that do not require any external element (weights, balls, cord). Gravity is the only force that exerts resistance.
This discipline develops strength, precision, and movement coordination, which are fundamental to increasing the difficulty of the exercises.
