Explanation:

1. For the first question, a polynomial is an expression consisting of variables and coefficients, combined using addition, subtraction, and multiplication (but not division by a variable). Physics, water, and substance are not relevant in this context.
2. For the second question, the numerical coefficient is the number part of a term. An exponent is a power to which a number or variable is raised, a literal - coefficient involves variables, and a variable is a symbol representing a value that can change.

Answer:

1. Polynomial
2. Numerical Coefficient
