Answer:density
Explanation:
At the bottom, deep bodies of water always measure because at that temperature water has it highest density .
In water bodies like lake warm water rises up due to convection and at higher depths there is cold water, which is found to be at highest density of water.
When water molecules acquired heat energy it become widely spread at the same volume and thus posses low density but at low temperature water molecule occupy less space therefore posses maximum density at
Answer:
8.27°
Explanation:
To angle difference will be determined by the difference in the displacement of the springs, produced by the weight of the center of mass of the rod.
by a simple trigonometric relation you obtain that the angle:
hence, the angle between the rod and the horizontal is 8.27°
Answer:
B. has the greatest mass
Explanation:
mass & distance affect pull
grativy affects speed & shape of orbit of the planet

Answer:
This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element. This means that if you know how many moles of aluminium you have in 4.55 g , you can use Avogadro's number to find the number of atoms.

Answer:I dont know
Explanation:
loyd is studying the effect of breakfast cereal on the health of rats. He suspects that the cereal may be unhealthy. He feeds rats various amounts of breakfast cereal over a six-week period. He weighs the rats using a digital lab balance at the beginning of the experiment and then again at the end of the experiment. Then, he calculates the change in weight.
When writing the conclusion of his report, Lloyd states that the breakfast cereal is not a healthy choice for school children since it causes them to gain weight unnecessarily.
What component of scientific argumentation is missing from Lloyds work?
graphs and tables in the written report
empirical data that supports his claim
appropriate equipment for use in the experiment
accurate measurements made during the experiment
