Answer:
m = 0.59 kg.
Explanation:
First, we need to find the relation between the frequency and mass on a spring.
The Hooke's law states that

And Newton's Second Law also states that

Combining two equations yields

The term that determines the proportionality between acceleration and position is defined as angular frequency, ω.

And given that ω = 2πf
the relation between frequency and mass becomes
.
Let's apply this to the variables in the question.

Answer:
The loudness of sound is most closely related to
The pressure within a sound wave determines the loudness of the sound. In this lesson, learn how to calculate the sound pressure level of a sound wave and what this measurement represents.
Explanation:
The rubber ducky was able to float because it’s density was less than the water. Water has a density of 1, meaning the rubber ducky must have a density lower than 1.
