Answer:
1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.
2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.
b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.
Explanation:
The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

Answer:
It would certainly make a difference.
Explanation:
The mass of a planet determines how thick the planets atmosphere would be, if it can even sustain an atmosphere. If all the masses are the same, all of the large planets would not be able to sustain life, while all of the smaller, denser planets still have a chance.
The mass of a planet also affects it’s gravitational pull. If all of the planets had the same mass, they would all have the same gravitational pull, meaning that they would all attract the same amount of asteroids, meteors, and other spacial objects.
Overall, the simulation would certainly be different, for many, many reasons. The above are only two, and if you would like more, just add a comment and I can give you more.
