The form of matter that is vapor is a gas made of a substance that is usually liquid.
Vapor is created when water, or some other liquid evaporates - meaning that it becomes so hot in a room, or wherever, that the liquid starts becoming gas.
Answer:
9.51 Hz
Explanation:
f₀ = frequency of tuning fork and fundamental frequency of the pipe initially = 240 Hz
T₀ = Room temperature = 20 °C
v₀ = speed of sound at room temperature
speed of sound at room temperature is given as
v₀ = 331 + (0.6) T₀ = 331 + (0.6) (20) = 343 m/s
L₀ = Length of the pipe
For open pipe, we have
v₀ = 2 L₀ f₀
343 = 2 (240) L₀
L₀ = 0.715 m
T = new temperature = 43.0°C
v = speed of sound at new temperature
speed of sound at new temperature is given as
v = 331 + (0.6) T = 331 + (0.6) (43) = 356.8 m/s
L = length of pipe = L₀ = 0.715 m
f = new fundamental frequency
For open pipe, we have
v = 2 L f
356.8 = 2 (0.715) f
f = 249.51 Hz
Δf = Beat frequency
Beat frequency is given as
Δf = f - f₀
Δf = 249.51 - 240
Δf = 9.51 Hz

Answer:
most bad weather arrives from the west
Explanation:
At different latitudes, the Earth has conveyor belts of air which affect weather like the westerlies and the trade winds. North America is most influenced by the westerlies, which come from the west
Answer:
Time = 4.1 s
Explanation:
Momentum = mv = (12000)(4.25) = 51000 kg m/s
Momentum = Impulse (mv = ft) so
51000 = (9200)t
t = (51000)/(9200) = 5.54 seconds
Impulse of the current and the engine must equal so (ft = ft)
51000 = (12500)t
t = (51000)/(12500) = 4.08
But accounting for significant figures, time equals 4.1 seconds
