Despite several studies being conducted, the exact cause of this phenomenon is yet to be ascertained. Women from Kodinhi married off to far away places are also known to give birth to twins. According to doctors this phenomenon is due to chemicals present in water in the Kodinhi area..

Understand and analyse the syllabus First cover the chapters you find easy quickly and then proceed to the chapters which you find difficult and give them proper amount of time and concentration After you have covered all the syllabus just attempt some mock tests and attempt the previous year question papers you can even download some separate papers for mental ability test and scholastic aptitude test from the internet aur even the my CBSE guide app As you know that that social science has a major wastage of marks that is 40 marks so focus on that and make sure your covered every chapter at least once That is my strategy and and I hope It helped you.... Good luck buddy ?

Hi David,

Nice hearing from you, I'm glad to hear you're getting by okay in these grim times.
You asked how’s it going for us back here in New Zealand.

You would have heard that the whole country is locked down and with breaks for exercise and shopping, we’re all living under a sort of voluntary house arrest.
The start of the lock down triggered in me an old feeling from past years.

From those car assembly strikes we took back in the ‘70s. The feeling at the strike’s onset; after our vote to stop, the conflicting feelings, the element of excitement, dare I say it, of fun. The usual boring routine suddenly wiped away, all of us together on the brink of an adventure, with a strong sense of collective purpose. A feeling of being vibrantly alive.

Then, as days passed, bills came and arguments at home increased, anxiety. The ‘****, how will we come out of this one ‘ feeling.

Well, this time we can’t hand the dispute over for the Trades Council to save our face, we can’t even call a mass meeting and agree to go back on the bosses terms.
We can only stay staunch and hold out for a win.

Of course a factory strike analogy goes only so far, like the analogies with World war 2 several people have cited.

Today we’re not in a strike or a war but confronted with international spread of a frightening virus with no known antidote.

It’s been quite a ride and we’ve found out some interesting things, even after just three days.

Some of us are much better placed than others. Despite government relief measures, thousands of workers will be struggling desperately. Some will lose their homes, many workers won’t get their jobs back.

The more conscientious union organisers are working harder than usual, from home, fielding calls for help. Hotlines for domestic violence calls are also on the up.

The situation in some deprived overcrowded New Zealand homes right now doesn’t bear thinking about and its still just early days under lockdown.

At the moment there’s understandable faith in the authorities line of march and positive response to the Prime minister’s injunction for everyone to be “kind to each other”. Some people angrily dismiss any questioning of our government over this.

Best to your and yours,

Don

Yogita Ingle 5 years, 1 month ago

<th>

1	Definition	Voltage, also called electromotive force is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points.	Current is just the rate of flow of electric charge. In simple words, the current is the rate at which electric charge flows in a circuit at a particular point.
2	Unit	The SI unit of voltage is Volts (V). Note: 1 Volt= 1 Joule/coulomb.	The SI unit of current is Ampere (A). Note: 1 Ampere = 1 coulomb/second.
3	Denotation	Voltage is denoted by “V”.	Current is denoted by “I”.
4	Measuring Instrument	Voltage can be measured by using a Voltmeter.	Current can be measured by using an Ammeter.
5	Inter-relation	Voltage is the cause of the current.	Current is the effect of the voltage i.e. current cannot flow without voltage.
6	Formula	One of the formulas to calculate voltage is: V= Work done/Charge	One of the formulas to calculate current is: I= Charge/ Time

Kavita Yadav 5 years, 1 month ago

To convert the given trigonometric ratios in terms of cot functions, use trigonometric formulas We know that, cosec2A – cot2A = 1 cosec2A = 1 + cot2A Since cosec function is the inverse of sin function, it is written as 1/sin2A = 1 + cot2A Now, rearrange the terms, it becomes sin2A = 1/(1+cot2A) Now, take square roots on both sides, we get sin A = ±1/(√(1+cot2A) The above equation defines the sin function in terms of cot function Now, to express sec function in terms of cot function, use this formula sin2A = 1/ (1+cot2A) Now, represent the sin function as cos function 1 – cos2A = 1/ (1+cot2A) Rearrange the terms, cos2A = 1 – 1/(1+cot2A) ⇒cos2A = (1-1+cot2A)/(1+cot2A) Since sec function is the inverse of cos function, ⇒ 1/sec2A = cot2A/(1+cot2A) Take the reciprocal and square roots on both sides, we get ⇒ sec A = ±√ (1+cot2A)/cotA Now, to express tan function in terms of cot function tan A = sin A/cos A and cot A = cos A/sin A Since cot function is the inverse of tan function, it is rewritten as tan A = 1/cot A
