Answer:
6 cm long
Explanation:
F = 4110N
Vo(speed of sound) = 344m/s
Mass = 7.25g = 0.00725kg
L = 62.0cm = 0.62m
Speed of a wave in string is
V = √(F / μ)
V = speed of the wave
F = force of tension acting on the string
μ = mass per unit density
F(n) = n (v / 2L)
L = string length
μ = mass / length
μ = 0.00725 / 0.62
μ = 0.0116 ≅ 0.0117kg/m
V = √(F / μ)
V = √(4110 / 0.0117)
v = 592.69m/s
Second overtone n = 3 since it's the third harmonic
F(n) = n * (v / 2L)
F₃ = 3 * [592.69 / (2 * 0.62)
F₃ = 1778.07 / 1.24 = 1433.927Hz
The frequency for standing wave in a stopped pipe
f = n (v / 4L)
Since it's the first fundamental, n = 1
1433.93 = 344 / 4L
4L = 344 / 1433.93
4L = 0.2399
L = 0.0599
L = 0.06cm
L = 6cm
The pipe should be 6 cm long
Hi ChloeRenee12345,
Your Question:
If the worlds human population stay away from all the fast foods that they purchase and consume their overall physical and mental state would be greatly affected
Answer:
Well absolutely not! Everyone will not be affected by not purchasing fast food, It will actually be better for the society. Fast food has bad properties that makes people get fat.
B.The water molecules in the black can had the largest increase in average kinetic energy.
<u>Explanation:</u>
Here, black painted can absorbs more heat than the other color painted cans.
Black color absorbs all the heat and didn't reflect anything back, so it absorbs the most heat.
White color reflects all the heat, so heat absorbed by the white can is least.
When the black can absorbs heat then the water molecules in the can gets its maximum amount of kinetic energy so that the water molecules in the can collide with each other and also along with the walls of the can here, and so the average kinetic energy increases.
Answer:
The main factors determining population distribution are : climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbors, navigable rivers or canals, cultural factors, political boundaries, controls on migration and trade, government policies
