Answer:
The energy source that does not use heat in the process of converting it to electricity is;
c. Sunlight
Explanation:
In converting Sunlight energy source to electricity, the photons in the light from the Sun excite electrons in the solar cells silicon layers, such that the electrons travel from n-type silicon layer to the p-type silicon layer creating electric potential energy that does work as the electrons flow back in the form of electricity from the p-type to the n-type silicon layer through an external circuit
Answer:
Incremental method.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.
In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
If you are just starting go on khan academy and go to the computing section and they will start you out on the basics on code devoloping.
Answer:
SELECT vendor_number, vendor_name, CONCAT ('street', ' ' , 'city', ' ' , 'state', ' ' , 'zip code') as adress
FROM vendor_directory
ORDER BY vendor_name ASC;
Explanation:
* Suppose <u>vendor_directory</u> is the name of the table from which you extract the data with the SELECT sentence.
