Transmutation involves -nuclear change -chemical change -both a nuclear and a chemical change -neither a nuclear nor a chemical
SVEN [57.7K]

Answer: Option (a) is the correct answer.

Explanation:

Transmutation involves the conversion of one chemical element into another chemical element. This change occurs when an element or isotope passes through a number of reactions. It is a natural process and happens when there is a radioactive decay.

Hence, it is also a nuclear change as it occurs when there is a change in the nucleus of an atom. As this change can be due to the nuclear decay so as a result there will be some change in energy also. It  is the process where one element converts into another using bombardment with high energy particles.

Thus, we can conclude that transmutation involves is a nuclear change.

A charged object (like a balloon that's been rubbed on the wall) cant attract an object with a net neutral charge (neither posit
UNO [17]

Answer: A balloon is charged by a process of frictional charging and the object is getting charged by the process of induction.

Explanation:

When two bodies are rubbed against each other, charging by friction or rubbing occurs. The electropositive object loses electrons to electronegative object. Thus, when balloon is rubbed on a wall, it becomes charged.

The charged balloon is able to attract an uncharged object by inducing charge on it without the two objects touching each other. Electrostatic force acts between two charged objects. Charged balloon causes electrons to move at one end thereby inducing opposite charge in the object and thus, charged balloon is able to attract uncharged object.
