Answer:

A and B are correct

Explanation:

<em>A</em> and <em>B</em> are the most logical answers from the 4 given. This is because just like the moon and Earth, Earth keeps the moon in its orbit with gravity.

A gravitational force can happen with any two objects in the universe. An example of this is a passing asteroid being pulled into Jupiter's atmosphere, because of the gravitational pull. Even two asteroids can have a gravitational pull/force on each other. If there is a big asteroid with smaller asteroids surrounding it, the smaller asteroids will "follow" the larger asteroid.

C is false, because the bigger the mass the bigger the pull (gravitational)

D is also false because if the gravitational force could only exist if there was contact, logically then the moon wouldn't still be orbiting Earth. In other words "Does the moon touch the Earth?" No, it does not "Is the moon still orbiting around Earth without contact?" Yes it is

The difference between the density of gas and the density of liquid
eduard

The molecules of a liquid substance are closely packed together to each other. So as a result, liquids are denser than gases.

<h3>What is the difference between the density of liquid and gas?</h3>

A mass of gas will have a much larger volume compared to the same mass of liquid. This is because it has a much lower density. The density of gaseous oxygen is 0.0014 g/cm3. Density is ρ=Mass Volume. We know that gas will uniformly occupy more space than liquid whatever volume is available to it. On the other hand, solids and liquids, are closely packed as compared to gas and are high-density materials where ρ is relatively constant.

So we can conclude that the molecules of a liquid substance are closely packed together with each other. So as a result, liquids are denser than gases.

What is the iupac name for this compound ch3-c(ch3) 2-ch2-chcl-ch3? ​
myrzilka [38]

The IUPAC name of the above mentioned compound is "2-Chloro-4,4-dimethylpentane"

<u>Exaplanation:</u>

  • Since the above organic compound is an compound with only one saturated bond, It can be considered as a single bond compound, and hence we can conclude that as alkane.
  • It also has 5 carbon atoms, so it is termed as pentane.
  • From right to left we have to number the atoms, and 2 nd carbon atom contain Cl atom so it is termed as 2-Chloro and in the 4th position carbon atom contains 2 methyl groups, so it is termed as, 2-Chloro-4,4-dimethylpentane.

The original gas volume in a balloon is 50.mL when the pressure is 1.00 atm. Predict the new gas volume when the pressure is 3 t
damaskus [11]
According to Boyle's law, Volume is indirectly proportional to the pressure.

So, P1V1 = P2V2

Substitute the known values, 
1 * 50 = 3 * V2

V2 = 50/3 = 16.67 mL

In short, Your Answer would be: 16.67 mL

Hope this helps!
