Jerry designed a coat that he thinks could keep people dry during a thunderstorm. He created a prototype that looks just like hi
AlekseyPX

Answer:

The next step is prototype testing

Explanation:

The stages of the design process are;

1) Situation analysis

Paper based research is conducted on the situation to obtain the situation parameters

2) Brief writing

With the situation analysis developed above, the brief of the current situation is put down on paper

3) Problem research

The problem is researched and experimented on with the development of a paper based proof of the possible concept

4) Specification writing

The specifications of the problem are outlined

5) List the possible solutions

The possible solutions are brainstormed and listed

6) Preferred solution selection

The preferred solution is selected based on the constraints in the situation

7) Create working drawing/plan

The working design drawing of the selected solution or concept is completed and evaluated for applicability

8) Building of a prototype

The design is converted into a prototype which is a model of the actual solution

9) Testing of the prototype

The prototype is tested for functionality, for ability to work in the intended situation and/or in the intended system

10) Report writing

A report is made on the outcome of the tests for review before production

Therefore, after the prototype is created, stage 8, the next step is the testing of the prototype stage 9.

This unit discusses in detail the role of catalysts to lower the activation energy of reactions. The term catalyst appears in no
Fynjy0 [20]
The scientific form made its way to common usage through the similarities in meaning. A catalyst is a chemical that speeds up the chemical reaction. In the Chernobyl story, the Chernobyl incident is understood as a catalyst for glasnost because it speed up the process of passing and activating the glasnost laws that opened the government policies more to the world and the people.

The term carries almost the same meaning because both a chemical catalyst and an event catalyst speed up the process of either the chemical reaction or the change of something, be it a government policy or a simple event among people or anything similar. Sometimes however, too much usage leads to incorrect usage where the common understanding of catalysts is different form the scientific usage.

It is used differently insofar that in scientific usage, the catalysts don't get affected chemically by the chemical reaction and the reaction itself is not chemically altered. What happens is just that the speed at which occurs is faster. However, in real world usage, it is often used incorrectly as catalysts being responsible for the change. In addition, the catalyst in real world events often influences the events and vice versa, which doesn't happen in chemistry other than increasing the speed. To explain this using Chernobyl, Glasnost wouldn't have happened on its own without the Chernobyl crisis, which means that the crisis is more of a cause than a catalyst that speeds up events.-
