<span>Bakers making fruit pies face the problem of the fruit juices running out into the oven and having a soggy crust. An ingenious way of preventing this is to put a paper cone made of thick brown paper in the hole at the center of the top
crust as you put the pie in the oven. When the fruit juice boils, it rises into this funnel and then goes back down into the pie, preventing the juice from overflowing all over the crust. Pinching together the upper and lower crusts will prevent the juice from seeping out from the edges.</span>
Answer:
wavelength = 2m
Speed = 342m/s
Explanation:
The length of the pipe in terms of the wavelength is expressed as;
L = v/4 (For closed pipe)
v = 4L
Given
L = 50cm
L = 0.5m
Get the wavelength v;
v = 4(0.5)
v = 2.0m
Hence the wavelength is 2.0m
The speed of the sound in pipe is expressed as;
Fo = V/4L
Fo is the fundamental frequency
V is the speed of sound
L is the length of the pipe
171 = V/4(0.5)
V = 171 * 2
V = 342m/s
Hence the speed of the sound in pipe is 342m/s

A fish pushes water backwards in order to move forward is a good example of Newton's 3rd Law.
Answer:
width of slit =1.23× 10⁻⁶ m
Explanation:
we know the condition of diffraction minima,
d sin θ = n λ
λ = wavelength θ = angle between the central maxima and 1st minima
d = slit width
for first minima n = 1
now,
d =
d =
d = 1228 × 10⁻⁹ m = 1.228× 10⁻⁶ m
d = 1.23× 10⁻⁶ m
width of slit =1.23× 10⁻⁶ m
