The answer is Calcium because it has a positive charge of 2. This makes it an atom of a chemical element that has an unequal number of electrons compared to protons. A neon is unlikely to become an anion by accepting another electron. Oxygen is a negative ion. A chlorine atom will become a charged ion with a negative charge of (-1).

The amplitude of a standing sound wave in a long pipe closed at the left end is sketched below. The vertical axis is the maximum
Rudiy27

Answer:

Check the explanation

Explanation:

A) 7th Harmonic. (Of an open ended pipe, odd harmonics are allowed (3rd overtone))

b) f = n v / 4 L

n = 7

f = 7 x 350 / 4 x 0.41 = 1493.9 Hz

c) Let level of water H, If reduces the effective length of pipe

Using, f = n v / 4 Leff

n = 1

251.8 = 1 x 350 / 4 ( 0.41 - H)

H = 0.0625m

H = 6.25 cm
