Answer:
a. verify that your observations are correct
c. think about what else might cause the observed discrepancy
Explanation:
Let's begin by explaining that a law is an affirmation (something established) based on repeated long-term observation of a phenomenon that has been studied and verified.
That is: A law is present in all known theories and therefore is considered universal. In addition, <u>a law can not be refuted, nor changed, because its precepts have been proven through various studies.</u>
Then, based on what is explained above, Kepler's laws of planetary motion exist because they were rigorously tested and verified, therefore they can not be refuted.
So, if we have a small discrepancy between the predicted and actual positions of Uranus after using Kepler's laws, we have to verify carefully our observations again and search what might be causing that discrepancy. But we cannot assume Kepler's Laws are incorrecto or need modifications.
In addition, we cannot consider that Uranus may not be a planet, because the discrepancy is small. In fact, this discrepancy lead to the discovery of another planet, Neptune.
Answer:
The mass of silver that will occupy a volume of 87.75 mL is 920.5 grams.
Explanation:
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

So the density of silver is 10.49 g / mL indicates that 10.49 g occupies a volume of 1 mL. Then a rule of three can be applied in the following way: if in 1 mL a mass of 10.49 g is occupied, in 87.75 mL how much mass will it occupy?

mass= 920.5 g
<u><em>

<span>Conduction is the process of freezing outside on a cold day. Conduction is usually the process of transfer of heat that is temperature from one body to another body which the difference in their heat energy. This transfer of energy which makes it freeze is also considered as conduction.</span>
P = 43 * 10^3
V = 12 L
P' =?
V' = 8 L
PV = P'V'
43*10^3* 12 = P' * 8
I know you can do it from here, mate ;)
