As the density of the unknown substance is 0.68g/0.8ml = 0.85g/ml, it is less dense than the maple syrup at 1.33g/ml and will float.
        
             
        
        
        
Answer:
The magnitude of the angular acceleration ∝ = ![\frac{rxF}{2.8[tex]r^{2}](https://tex.z-dn.net/?f=%5Cfrac%7BrxF%7D%7B2.8%5Btex%5Dr%5E%7B2%7D) }[/tex]
}[/tex]
Explanation:
The angular acceleration ∝ is equal to the torque (radius multiplied by force) divided by the mass times the square of the radius. The magnitude of angular acceleration ∝ will have the equation above but we have to replace the mass in the equation by 2.8kg as stated.

Answer:
The index of refraction of the liquid is n = 1.33 equivalent to that of water
Explanation:
Solution:-
- The index of refraction of light in a medium ( n ) determines the degree of "bending" of light in that medium.
- The index of refraction is material property and proportional to density of the material. 
- The denser the material the slower the light will move through associated with considerable diffraction angles. 
- The lighter the material the faster the light pass through the material without being diffracted as much. 
- So, in the other words index of refraction can be expressed as how fast or slow light passes through a medium. 
- The reference of comparison of how fast or slow the light is the value of c = 3.0*10^8 m/s i.e speed of light in vacuum or also assumed to be the case for air.
- so we can mathematically express the index of refraction as a ratio of light speed in the material specified and speed of light.
- The light passes through a liquid with speed v = 2.25*10^8 m/s :
                          
- The index of refraction of the liquid is n = 1.33 equivalent to that of water.
