Answer:
A. Vegetable oil
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
Hence , from the question ,
A. Vegetable oil is a non polar compound ,
B. Polar compound
C. ionic compound , is a polar compound .
Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,
Therefore ,
Water will not get dissolved in vegetable oil , being it a non - polar compound .
Answer:
A. Repel
Explanation:
A magnet comprises of north and south poles.
When the south magnetic poles of two magnets are brought together, the magnets will repel because they are like charges and like
charges repel each other.
But when the north magnetic pole of one magnet is brought together with the South Pole of another magnet, both magnets will attract because they have different charges + and - . Positive and negative charges attract .

G: ocean water evaporates to water vapor on a hot day
Because it requires more energy to create a neutron from a proton than it does to create a proton from a neutron, protons were formed more frequently than neutrons in the early universe. The correct answer is option b.
To find the answer, we need to know more about the early universe.
<h3>How the formation of proton over neutrons was favored in the early universe?</h3>
- A neutron is produced with greater energy than a proton.
- However, later on, some of the protons were changed into neutrons.
- Contrary to some claims, the proton is a stable particle that never decays, but the neutron is unstable outside of the nucleus and decays with a half life of around 10.5 minutes.
- However, very few would have had time to decay on the timeline you mention in your question.
- Every matter particle should have been accompanied by an antimatter particle, and every proton, neutron, and electron, by an anti-neutron and a positron, respectively.
- Where did all the antimatter go is the great mystery. There have been a few attempts to explain this, but they have failed.
Thus, we can conclude that, the correct answer is option b.
