Question

Which of the following is typically part of the knowledge base of research and development scientists working on heating devices? (1 point)

O substances and their properties
O engineering rules and principles
O marketing strategies
O sales projections

Answer 1

Research and development scientists working on heating devices typically need knowledge of substances and their properties, as well as engineering rules and principles. Marketing strategies and sales projections are not typically part of their knowledge base.

Step-by-step explanation:

Research and development scientists working on heating devices typically have a knowledge base that includes substances and their properties. They need to understand the characteristics and behaviors of different substances used in heating devices to ensure safety and efficiency.

Additionally, engineering rules and principles are crucial for these scientists. They must have a solid understanding of the fundamental principles and concepts related to heat transfer, thermodynamics, and fluid dynamics to design and optimize heating devices.

On the other hand, marketing strategies and sales projections are not typically part of their knowledge base. These aspects are more relevant to the business and sales departments of a company.
