Answer:
The frequency of the sound wave in the helium in the stopped pipe is 749.25 Hz.
Explanation:
Given that,
Length = 1.00 m
Temperature T = 20°C
Speed of sound = 999 m/s
We need to calculate the frequency of the sound wave in the helium in the stopped pipe
Using formula of frequency
Put the value into the formula
Hence, The frequency of the sound wave in the helium in the stopped pipe is 749.25 Hz.
WARMER AND WETTER BIOMES GENERALLY HAVE MORE PLANTS, WHICH NEED MORE SUNLIGHT. THE SUNLIGHT CONTRIBUTES TO THE HIGHER NET PRODUCTIVITY
Note that 1 mL (milliliter) = 1 cm^3.
The volume of water is
Vw = 50.00 mL = 50 cm^3
From tables, the density of aluminum is 2.7 g/cm^3.
Because mass = density * volume, the volume of the aluminum is
Va = (15 g)/(2.7 g/cm^23) = 5.556 m^3
Because the aluminum sinks and displaces water in the cylinder, the new volume is the sum of the volume of water and the aluminum.
New volume = Vw + Va = 50 + 5.556 = 55.556 cm^3
Answer: 55.6 cm³ (nearest tenth)
