Answer:
The correct approach will be "Polymer".
Explanation:
- A polymer, because it has a very broad molecular structure, seems to be a class or kind of organic solid. It is indeed a material consisting of long sequences, or monomers, of simplified components.
- The existence of a large number of monomers which have been mentioned several times seems to be the principal design characteristic of polymeric materials.
Answer:
To indicate the welding or cutting processes
Answer:
starburst
Explanation:
There are many different kinds of "hazard symbols," which are being used in order for people to recognize what kind of material they are handling. When it comes to "pictograms," the symbol for a hazard class of explosive is an exploding bomb that shows a<em> starburst effect.</em> An example of such chemical is the <em>"organic peroxide" </em>and other<u> self-reactive chemicals.</u>
A "flame" is a hazard symbol for<em> flammable substances</em>. A<em> </em>"gas cylinder" is a hazard symbol for <em>gases that are located in containers that are under pressure.</em> A "test tube" is a hazard symbol for <em>substances/materials that cause corrosion to skin.</em>
Answer:
Explanation:
1) Resolution and uncertainty of both ADC ranges
a) Resolution (for +/- 5 mV range) = 5 mV / 2n where n = number of bits of ADC
Resolution = 5 mV / 28 = 5 mV / 256 = 0.0195 mV ..................1
uncertainty (for +/- 5 mV range) = +/- 0.5*resolution = +/- 0.5*0.0195 mV = 0.00975 mV ..........2
b) Resolution (for +/- 5 V range) = 5 V / 2n where n = number of bits of ADC
Resolution = 5 mV / 28 = 5 V / 256 = 0.0195 V = 19.5 mV ..................3
uncertainty (for +/- 5 mV range) = +/- 0.5*resolution = +/- 0.5*19.5 mV = 9.75 mV ..........4
2)Thermocouple sensitivity = ( Maximum output voltage - Minimum Output voltage) / (Maximum Temperature - Minimum Temperature)
Thermocouple sensitivity = (3.649mv - 0 ) / (70 - 0) = 0.0521 mV / Deg.C ............5
This is the required Thermocouple sensitivity
3) Water bath temperature is given as 57 deg.C
Hence voltage read by Thermocouple = Sensitivity*57 = 0.0521*57 mV = 2.9697 mV ........6
4)We need to use ADC with a range of +/- 5 mV range as ADC with +/- 5 V range can not do measurement as it's resolution is higher than output voltage.
ADC will measure voltage as 2.9695 mV ......................7
