The density of the clay plate is 1970 kg m⁻³
the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams
so,V= 30 cm⁻³=3x 10-5 m and M= 59.1grams= 0.0591 kg
Therefore, the density of the plate is: M/V
=>d = 1970 kg m⁻³

The scientific method's foundation is best described as "the process of hypothesis and testing through which scientific inquiry happens." Thus, the correct option is D.
<h3>
What is scientific method?</h3>
The scientific method is a set of actions that are followed in order to develop scientific knowledge.
The scientific process includes the following steps:
- To make observations on a particular natural occurrence and then generate questions based on those observations.
- To answer these questions, you must propose a credible explanation (i.e., a hypothesis).
- To put the working hypothesis to the test using experimental and/or observational methods.
- To gather information in order to confirm or refute a working theory.
- Analyze the findings and develop conclusions.
