What is the difference between hardness and TDS in water?
Referring to all the 3 answers above (which are correct obviously), The symptom of hard water is that there is less amount of foam formation during mixing of soap in plain water. Whereas, the symptom of TDS is the taste of water, little different from the treated water.You can use an instrument called TDS meter (costing appx 500–1000 on amazon) , just insert & you know the TDS. It is in PPM as stated above. Very vaguely, the Hardness is 1/2 of the TDS (not always) for untreated water.TDS is the Total Dissolved (looking like , but not actually dissolved) solids in water.As far as drinking water is concerned , upto 200 TDS water is safe for drinking. Even upto 400 also it’s fine. But testing that is good. You can know the impurities and get a system which will remove those. Generally RO is the best.
What is the difference between growth and development?
In economic sense (as far as I know…) Growth is a process of expanding or becoming large over a certain period. It specifically has nothing to do as far as qualitative expansion is concerned or in other words it is a term which depicts quantitative enlargement of a particular thing.Whereas,Development is a wider term and includes growth i.e it is more of a comprehensive concept which not only includes quantitative enlargement but also includes qualitative expansion.Growth may or may not be good for a particular criteria (or at least in economics..) but Development more often signifies a positive attitude..Now let's take an exampleThe population of our country is growingthe sentence expresses the increase or expansion of population but this may not be a good indication for our economyIn another example,The industrial sector of our country has developed over the decadeNow in this sentence development of a sector is expressed to have happened and this indeed is a good indication for our economy!That is why rate of development is used in real senses to compare two aspects as it gives an accurate and correct base on which those two aspects should be compared….After all quality matters more than quantity!I hope it helped…thanks for reading and my apology if I've made any mistake :-):-)

What are the differences between live, earth and neutral wire?
In an appliance which takes power from single phase supply, the typical structure of power cable consists of three wires as below.However, in a three phase system, there are three live wires. The typical color code for a three phase system in comparison to single phase system is given below.The circuitry in three phase system is a little different than single phase system.Interestingly, neutral and earth are both grounded wires with one subtle difference, that is neutral is grounded where the transformer is located and earth is a local ground beside a house with an access to electricity.Image source: Google image search
How can you tell if someone hung up the phone or you got disconnected?
ask them... not really any way to tell with a land phone... with a cell phone, if your side of the call lost connection there is usually some indicator tone that the connection was lost..
