The jetliner is traveling against the wind. The net speed of the jetliner is
590 mph - 36 mph = 554 mph
The time it takes for the jetliner to arrive at the destination is
1850 miles / 554 mph = 3.34 hours
Answer:
I think the correct answer is B.
Answer:
their weight difference
Explanation:
weight adds to kinetic energy. a heavier object will have a higher kinetic energy because the extra weight will slowly increase or decrease the velocity depending on if it's being sent down a decline or inclined plane
Each time a uranium nucleus splits<span> up it releases energy and three neutrons. If all the neutrons are allowed to be absorbed by other uranium nuclei the chain reaction will spiral out of control causing an explosion. To control the energy released in the reactor moveable control rods are placed between the fuel rods.</span>
Complete question:
Calculate the length of a pipe that has a fundamental frequency of 232 Hz. (Take the speed of sound in air to be 343 m/s.)
a) Assume the pipe is closed at one end. m
(b) Assume the pipe is open at both ends. m
Answer:
(a) The length of the pipe if it is closed at one end is 0.37 m
(b) The length of the pipe if it is open at both ends is 0.74 m
Explanation:
Given;
fundamental frequency of the pipe, F₀ = 232 Hz
speed of sound in air, V = 343 m/s
(a) Assuming a closed pipe, the wavelength of the fundamental frequency is given by;
L = λ₀/4
λ₀ = 4L
The relationship between frequency, wavelength and speed is given by;
V = F₀λ₀
substitute the value of λ
V = F₀(4L)
V = 4F₀L
L = V / 4F₀
L = (343) / (4 x 232)
L = 0.37 m
(b) Assuming an open pipe, the wavelength of the fundamental frequency is given by;
L = λ₀/2
λ₀ = 2L
V = F₀λ₀
substitute the value of λ
V = F₀(2L)
V = 2F₀L
L = V / 2F₀
L = (343) / (2 x 232)
L = 0.74 m
