Answer:
Weight of object = 11.2 N
Apparent weight = 3.83 N when immersed
Weight of water displaced = 11.2 - 3.83 = 7.37 N
d (density) W / V weight / volume the weight density
Wo = Vo do weight of object
Ww = Vo dw where Ww is weight of equivalent volume of water = 7.37
Wo / Ww = do / dw dividing previous equations
do = 11.2 / 7.37 dw = 1.52 dw
The density of the object is 1.52 that of water
The density of water is 1000 kg / m^3 * 9.8 m/s^2 = 9800 N/m^3
So the weight density is 14900 N/m^3
I think the answer is digestive system

<h3><u>Answer;</u></h3>
Each will reflect at an angle equal to its angle of incidence.
<h3><u>Explanation;</u></h3>
- <em><u>When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves. Reflection occurs such that the incidence angle is equal to the angle of reflection.</u></em>
- Reflection of light depends on whether the surface is smooth or rough. When the light hits a smooth surface it bounces off the surface and all the rays of light moves in the same direction, this type of reflection is called specular reflection.
- On the other hand , when right rays hits a rough surface the rays bounces off the surface and the rays move in different directions, a type of reflection called diffuse reflection.
Answer:
The Improbability Principle: Rare events and coincidences happen all the time.
9*9=81 ,a good way to remember is 9 times 2 is 18 so u just flip it
