Answer:
The mass of the cargo is
Explanation:
From the question we are told that
The radius of the spherical balloon is
The mass of the balloon is
The volume of the spherical balloon is mathematically represented as
substituting values
The total mass the balloon can lift is mathematically represented as
where is the density of helium with a value of
and is the density of air with a value of
substituting values
Now the mass of the cargo is mathematically evaluated as
Use the concept of beat frequency to find the applicable final freqeuncy for 20Hz beat frequency.
Beat can be defined as 'the interference pattern between two sounds of slightly different frequencies0
The expression for beat frequency is given as
Where,
Final frequency
Initial frequency
The beat frequency for us is 25Hz and the initial frequency is 240Hz, then
Being an absolute value, two values are possible, both in addition and subtraction:
The two possible values are
