I can answer the first question: Water rises because of the sun's heat and turns into water vapor. After that, it gathers up and forms a cloud. When the cloud is filled enough with vapor, precipitation occurs.
Answer:
Final kinetic energy,
Explanation:
It is given that,
Initial gravitational potential energy of the satellite,
Initial kinetic energy of the satellite,
Final gravitational potential energy of the satellite,
Let is the final kinetic energy of the satellite at that point. Using the conservation of energy to find it as the energy of the satellite remains constant.
So, the final kinetic energy of the satellite at that point is 4000 MJ. Hence, this is the required solution.
Answer:
Toothpaste
Explanation:
When red litmus paper turns blue, it's a clear indicator that the solution or item where it was put is basic. The most common household item which is known to be basic is toothpaste. Experimental studies show that when you put red litmus paper into toothpaste solution, it turns blue.

Answer:
Frying an Egg
Explanation:
When chemical bonds are broken or formed, new particles are created. Therefore, frying an egg is a chemical change because it results in the formation of new particles.
