Answer:
See Explanation
Explanation:
Given
(a) to (d)
Required
Determine whether the given parameters can calculate the required parameter
To calculate either Density, Mass or Volume, we have



(a) 432 g of table salt occupies 20.0 cm^3 of space
Here, we have:


The above can be used to calculate Density as follows;



(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3
Here, we have:


This can be used to solve for Volume as follows:



(c) 32 cm^3 sample of gold density of 19.3 g/cm^3
Here, we have:


This can be used to calculate Mass as follows:



(d) 150 g of iron, density of Iron = 79.0 g/cm^3
Here, we have


This can be used to calculate volume as follows:


<em>Approximated</em>
First use this equation to find the wave speed: vms== =τµ/ 0.4/ 0.001 20 / Then use the equation for solving frequency of a wavelength, and solve for wavelength λ = v/f = 20/100 = .2 m = 20 cm.
