Answer: Option (A) is the correct answer.
Explanation:
The process in which two or more small nuclei combine together to result in the formation of a larger nuclei is known as fusion.
In Sun, four hydrogen nuclei combine together to result in the formation of helium atom. This combining of small hydrogen nuclei to form a large helium nuclei represents fusion process occurring inside the Sun.
Thus, we can conclude that to power itself, the sun is constantly generating a nuclear reaction in its core, in which hydrogen nuclei are combined to form helium. This process is known as fusion.
Answer: -
Without the sun, life on earth would not exist. There would be no warmth, no plants, no animals, no night and day.

A) Fusion
Fusion produces a lot of energy but very little radioactive waste.
Answer:
C. Molecules or ions of a solute spread throughout the water molecules.
Explanation:
C. Molecules or ions of a solute spread throughout the water molecules.
Protons and electrons have the same mass.
b
Protons have a positive charge and are found in the nucleus.
c
Neutrons are negative and are found outside the nucleus.
d
Electrons are negative and are found in the nucleus.
The statement which is true about the subatomic particles within an atom is as follows:
Thus, the correct option is B.
Subatomic particles may be defined as those particles that significantly compose an atom. Such particles are generally smaller than atoms. In other words, it can be said that the subatomic particles are united together to form any atom.
Protons are positively charged subatomic particles that are found in the nucleus of an atom. Electrons are negatively charged subatomic particles that are significantly revolving around the nucleus of an atom.
Neutrons do not have any charge, they are neutral and are found in the nucleus of an atom along with protons.
Therefore, the correct option for this question is B.

The rate of cooling of the water is 2.5°C per minute, calculated by using the difference in temperature over the time interval and assuming a linear rate of cooling.
The rate of cooling of water is the change in temperature over time. If the temperature of water drops from 60 degrees Celsius to 35 degrees Celsius in ten minutes, we can calculate the rate by subtracting the final temperature from the initial temperature and then dividing by the time elapsed. The formula for the rate of cooling is:
Rate of cooling = (Initial Temperature - Final Temperature) / Time
In this case:
Rate of cooling = (60°C - 35°C)/10 minutes = 2.5°C per minute
This calculation assumes that the cooling process follows a linear rate, which might not be the case in real-world scenarios as the rate can change over time due to various factors such as the properties of the container, the environment, and the volume of water.
