Answer:
When the string on a violin vibrates, waves move in both directions along the string, interfering with each other. These waves are standing waves.
Explanation:
What are Standing Waves?
The Standing Waves are waves generated due to the vibrational frequency that produces reflected waves capable of interfering with the incident waves.
Answer:
The answer is
<h2>11.73 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of object = 30.5 g
Density = 2.6 g/cm³
The volume is
We have the final answer as
<h3>11.73 mL</h3>

Organic molecules typically do not contain the noble gases, so they would contain all but Ne
Answer:
101.50 g H₂O
Explanation:
The mole ratio of HNO₃ and H₂O is 6 : 2
Hence, 16.9 moles of HNO₃ will produce = 2/6×16.9 = 5.63 moles of H₂O
Also,
Mass = Moles × M.Mass
Mass = 5.63 mol × 18.02 g/mol
Mass = 101.50 g H₂O
