1. are atoms of an element with different numbers of neutrons 2. positively charged particles of the central nucleus of an atom 3. electrically neutral particles of the central nucleus of an atom are negatively charged particles surrounding the central nucleus of an atom 5. are two or more atoms held together by a chemical bond

The answer to your question is below:

Explanation:

1. _Isotopes__ are atoms of an element with different numbers of neutrons

2. _Protons positively charged particles of the central nucleus of an atom

3. _Neutrons__ electrically neutral particles of the central nucleus of an atom 4.__Electrons__ are negatively charged particles surrounding the central nucleus of an atom

5. _Molecules___ are two or more atoms held together by a chemical bond

conduction, convection, radiation

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
