What is electro-chemical series?
It is a vertical series in which different electrodes/substances are arranged in the increasing order of their REPVs with the standard Hydrogen Electrodes (SHE) / Normal Hydrogen Electrode (NHE) in the middle of the series which is assigned an REPV of 0 voltage.Note- REPV stands for Standard Reduction Electrode Potential Values.
RoHS restricts use of which substance?
The Restriction of the use of certain Hazardous Substances (RoHS) Directive restricts the producers of eight categories of electrical and electronic equipment from placing on the market products that contain six "banned" substances unless specific exemptions apply. These six substances are: Lead, Mercury, Hexavalent chromium, Cadmium, Polybrominated biphenyl flame retardants and Polybrominated diphenyl ether flame retardants. The phrase 'banned' is misleading as you can have minute concentrations values but they are so small that it effectively prevents their use. The maximum concentration values (MCV) are 0.1 % by weight of lead, mercury, hexavalent chromium, PBB and PBDE and 0.01 % by weight cadmium in homogeneous materials.
How did mendeleev decide how to arrange his cards of elements?
Mendeleev used the analogy of playing the card game of solitaire to help him organize the known elements into a periodic table. The suits of the cards were analogous to the groups of the elements and the numeric values of the cards were analogous to the values of atomic weights.
Substances with pH values close to 14 are strong?
A strong acid always has a pH much lower than 14.
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
What is ordered value bar graph?
An ordered value bar graph is a value bar graph in which data values are arranged in increasing (or decreasing) order of length.
Why are the values of our society decline?
They're not. Our society's values in terms of freedom are increasing, not decreasing.
Mean equals 26.8 and median equals 27.9 then what is mode?
A specific value for the mode cannot be given with the information provided. The arithmetic mean = Sum of all the values ÷ The number of values. The median is the value which lies halfway along the series when arranged in ascending or descending order. The mode of a set of values is the value which occurs most frequently.
What does quantization refer to?
Having a specific set of possible values
The slope of line which has decreasing y values for increasing x is?
... negative.... negative.... negative.... negative.
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
What is the middle number in a set data after the data is arranged from least to greatest?
The median value of a range of values.
What is the median of 1000 data values?
When they are arranged in order, it is the number halfway between the 500th and 501st value.
What expresses a functions pattern in words?
A function's pattern can be described in words by stating how the input values relate to the output values. This can include describing whether the function is increasing, decreasing, constant, or has a specific shape like a curve or straight line. Additionally, it can involve explaining any repeats, symmetry, or other characteristics of the function's behavior.
When specific values if one variable tend to occur in common with specific values of another?
what do we call a measure that is relatively unaffected by extreme observations
What are kinds of values?
There are many kinds of values, including moral values (e.g., honesty, respect), ethical values (e.g., fairness, integrity), cultural values (e.g., traditions, beliefs), and personal values (e.g., loyalty, independence). Values guide our choices and actions, shaping our behavior and character.
In a linear equation the independent variable increases at a constant rate while the dependent variable decreases at a constant rate the slope of this line is?
The slope is negative. This just means that your x-values (independent) are increasing (which is usually the case). Such as 0,1,2,3,4,5. While the y-values (dependent) are decreasing. such as -5,-4,-3,-2,-1,0. Since the y-values are decreasing, this must mean the slope has to be negative.
