Answer:
0.68 m
Explanation:
We know that the speed of sound in air is a product of frequency and wavelength. Taking speed of sound in air as 340 m/s
V=frequency*wavelength
Then wavelength is given by 350/500=0.68 m
Therefore, to repeat constructive interference at the listener's ear, a distance of 0.68 m is needed
Explanation:
The frequency of an organ pipe if it is open is given by :
v is speed of sound in air is 343 m/s at 20°C
For fundamental frequency, n = 1
First overtone frequency,
Second overtone frequency,
Third overtone frequency
Hence, this is the required solution.
Answer: A
Explanation: You need to find the dimensions of the scale model of the lot that can be multiplied equally to get the original length. Basically 40 m and 100 m need to be divided by the same number to make the scale model evenly, and right off the bat you see that 10 and 25 could be multiplied by 4 and equal the original numbers. Hope this helps! Also sorry if it was kinda hard to understand lol, when i explain things its hard to get out of my own head ;P

Answer:
Electronegativity is a chemical property at the top of the periodic table
Explanation:
electronegativity is a chemical property that measures the ability of an atom to attract a bonding pair of electrons when it is part of a compound
it's a property of atom that increases as you go to the right and up.
One example is the Pauling scale. it is a numerical scale of electronegativities. It was first developed by Linus Pauling.
it is commonly used to calculate the ability of electronegativity to attract electrons to itself.
The most common electronegative element is Flourine, having an assigned value of 4.0, ranging down to caesium and francium, having the least electronegative at 0.7
