<span>B. Controls: The known powders attributes are already studied, so the are used as control measures to compare with the findings in the experiment with the unknown powders.</span>
A.)When heated, the molecules get loser, and the dipole dipole interaction is still there, but they dont stay so closely together, and jossle around with momentary meetings of opposite charges
B.The heat is used to break the bonds between the ice molecules as they turn into a liquid phase<span>. </span>
<h2>
a) Volume of anchor is 0.019 m³</h2><h2>
b) Weight of anchor in air is 1463.17 N</h2>
Explanation:
a) Weight loss in water = Volume of object x density of water x acceleration due to gravity
183 = Volume of anchor x 1000 x 9.81
Volume of anchor = 0.019 m³
b) Weight = Mass x acceleration due to gravity = Volume x Density x acceleration due to gravity
Weight of anchor in air = Volume of anchor x Density of anchor x acceleration due to gravity
Weight of anchor in air = 0.019 x 7850 x 9.81 = 1463.17 N
Weight of anchor in air = 1463.17 N
You should write ' 4 ' in the first box,
and ' m/s² ' in the second box.
They maintain the same distance between each other throughout the fall
