The correct answer is frequency.

The pitch can be defined as the quality of sound produced by the rate of vibration producing it.

It is directly related to the the frequency of the sound wave. If the frequency is increased then its pitch will also increase and vice versa.

As for normal people it is a bit difficult to differentiate between the two but the musician are trained so they can differentiate the difference between the two even if the difference is 2 Hz

A patient is scheduled for a fiberoptic colonoscopy. what does the nurse know that fiberoptic colonoscopy is most frequently use
Naya [18.7K]
During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.

Find the amount of work done in emptying a cylindrical tank completely filled with kerosene. Assume that the radius of the cylin
Aleks [24]
The formula for the work done in emptying a tank is this:
W = ωyV

where
ω is the specific weight
y is the center of gravity
V is the volume of the liquid

The specific weight can be calculated using the formula
ω = ρg
where
ρ is the density
g is the acceleration due to gravity

Solving for ω
ω = 817.15 kg/m3 (9.81 m/s2)
ω = 8016.24 N/m3

The center of gravity of a completely filled cylindrical tank is just 1/2 of the height. So,
y = 3 cm

The volume of the kerosene is just the volume of tank. Using the formula for the volume of a cylinder
V = πr²h
V = π (3²) (6)
V = 54π m³

Therefore, the word done is
W = 8016.24 (6) (54π)
W = 8159538.47 J or
W = 8.16 MJ
