The change that is undergone by an atom of an element made radioactive by bombardment with high-energy protons is called(1) natural transmutation(2) artificial transmutation(3) natural decay(4) radioactive decay

Answers

Answer 1
Answer:

Answer: The correct answer is Option 2.

Explanation:

Natural transmutation is defined as the decay process of the radioactive elements which occur spontaneously by a process that causes transmutation.

Artificial transmutation is defined as the process where artificially induced nuclear reaction is done by the bombardment of nucleus with high energy particles on a radioactive element. It is a spontaneous reaction.

Natural decay or radioactive decay are the processes in which a nucleus disintegrates spontaneously on its own. There are many processes by which this decay takes place.

Hence, the correct answer is Option 2.
Answer 2
Answer:

Final answer:

Artificial transmutation is the process where an atom of an element is made radioactive by bombardment with high-energy protons. This process was exemplified by Ernest Rutherford when bombarding nitrogen atoms with alpha particles. Thus, changes in atomic structure due to high-energy proton bombardment are results of artificial transmutation.

Explanation:

The change undergone by an atom of an element made radioactive by bombardment with high-energy protons is called artificial transmutation. This is a process of nuclear chemistry, which involves the conversion of one nuclide into another. It can occur through the radioactive decay of a nucleus or via the reaction of a nucleus with another particle.

An example of artificial transmutation was evident in the early work of Ernest Rutherford. In 1919, he bombarded nitrogen atoms with high-speed alpha particles from a natural radioactive isotope of radium and observed protons resulting from the reaction. Thus, artificial transmutation is the process responsible for the alteration in atomic structure when an element becomes radioactive due to bombardment by high-energy protons.

Which statement is true because of newtons second law ?a)when the net force on an object increases, the objects acceleration decreases
b)when the net force on an object decreases ,the objects acceleration increases
c)when the net force on an object decreases, the acceleration doesnt change
d)when the net force on an object decreases, the objects acceleration decreases

Answers

Newton's second law, by definition, states that,  The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Therefore, based on the given options above, the correct answer would be option D: when the net force on an object decreases, the objects acceleration decreases.

d. when the net force on an object decreases, the objects acceleration decreases
