Answer:
D
Explanation:
Both the joule and the kelvin represent heat. Kelvin is a unit of measurement for temperature and joule is more heat energy.
Answer:
B. 152.64
Explanation:
The average value of a sinusoidal waveform taken over half cycle is given by
or simplifying it further results in;
We are given
Hence option B is the right answer
Please note:
The average value of a pure sinusoidal wave over a full cycle (0 to 360°) is always zero since the positive and negative half cancel out each other due to being symmetric.
This is why we always take average over half cycle (0 to 180°).
The engineering design process is a common series of steps that engineers use in creating functional products and processes.
Steps of the Engineering Design Process
Define the Problem. The engineering design process starts when you ask the following questions about problems that you observe: ...
Do Background Research. ...
Specify Requirements. ...
Brainstorm Solutions. ...
Choose the Best Solution. ...
Develop the Solution. ...
Build a Prototype. ...
Test and Redesign.
Process Engineer responsibilities include:
Developing, configuring and optimizing industrial processes from inception through to start up and certification. Assessing processes, taking measurements and interpreting data. Designing, running, testing and upgrading systems and processes.
