Answer:
13.069 g/cm^3
Explanation:
to get density, simply divide the mass by the volume. Your equation would look like this; p=562/43
'P' represents density in this equation. Never forget to add your units!
Hope this helps!
Scientists use models to help explain an idea, visualize hypotheses, and closely examine something (such as an atom).
Answer:
The value is 
Explanation:
From the question we are told that
The frequency of each sound is 
The speed of the sounds is 
The distance of the first source from the point considered is 
The distance of the second source from the point considered is 
Generally the phase angle made by the first sound wave at the considered point is mathematically represented as
![\phi_a = 2 \pi [\frac{a}{\lambda} + ft]](https://tex.z-dn.net/?f=%5Cphi_a%20%3D%20%202%20%5Cpi%20%5B%5Cfrac%7Ba%7D%7B%5Clambda%7D%20%20%2B%20ft%5D)
Generally the phase angle made by the first sound wave at the considered point is mathematically represented as
![\phi_b = 2 \pi [\frac{b}{\lambda} + ft]](https://tex.z-dn.net/?f=%5Cphi_b%20%3D%20%202%20%5Cpi%20%5B%5Cfrac%7Bb%7D%7B%5Clambda%7D%20%20%2B%20ft%5D)
Here b is the distance o f the first wave from the considered point
Gnerally the phase diffencence is mathematically represented as
![\Delta \phi= \phi_a - \phi_b = 2 \pi [\frac{ a}{\lambda} + ft ] - 2 \pi [\frac{b}{\lambda} + ft ]](https://tex.z-dn.net/?f=%5CDelta%20%5Cphi%3D%20%5Cphi_a%20-%20%5Cphi_b%20%20%3D%20%202%20%5Cpi%20%5B%5Cfrac%7B%20a%7D%7B%5Clambda%7D%20%20%2B%20ft%20%5D%20-%202%20%5Cpi%20%5B%5Cfrac%7Bb%7D%7B%5Clambda%7D%20%20%2B%20ft%20%5D)
=> ![\Delta \phi = \frac{2\pi [ a - b]}{ \lambda }](https://tex.z-dn.net/?f=%5CDelta%20%20%5Cphi%20%20%20%3D%20%20%20%5Cfrac%7B2%5Cpi%20%5B%20a%20-%20b%5D%7D%7B%20%5Clambda%20%7D)
Gnerally the wavelength is mathematically represented as
=> 
=> 
=> ![\Delta \phi = \frac{2* 3.142 [ 4.40 - 4.0 ]}{ 0.611 }](https://tex.z-dn.net/?f=%5CDelta%20%20%5Cphi%20%20%20%3D%20%20%20%5Cfrac%7B2%2A%203.142%20%5B%204.40%20-%204.0%20%5D%7D%7B%20%200.611%20%20%7D)
=>
A block of plastic released under water will come up to the surface of the water because the density of the plastic is less than the density of water.
<h3>
What is density?</h3>
Density is the amount of mass a substance contains per its unit volume. It means the number of particles that can be packed into a unit space of that substance.
<h3>
How does density determine whether an object will float or sink?</h3>
When an object is immersed in a liquid, it experiences two forces - gravitational force and an upward buoyant force called upthrust. If the density of the object is more than the density of the liquid, gravitational force will be greater than upthrust and the object will sink, but if the density of the object is less than the density of the liquid, upthrust will be greater than gravitational force and the object will float. That is why a block of plastic will come up to the surface when released under water, because it is less dense than water.
