Hi,
Meteorologist jobs in India can be at very different levels and there are huge career prospect for a qualified meteorologist. The prospective fields for a meteorologist are:
Daily weather forecasting. Daily weather forecasting is very important for Govt departments like Agriculture and some other offices.
Each and every airport has a Met office(meteorology office) adjacent to it for time to time weather and visibility forecasting which require qualified meteorologists.
Indian Meteorological department.
Atmospheric research
Teaching
Broadcasting in different services: A climatologist or Meteorologist can easily a grab daily weather forecasting jobs for TV Channels, and for News agencies
As Architectural Climatologist: The growing India is in dire need of structures. Not only building of houses we need more structures in terms of offices, bridges, flyovers etc. to build up the new India for which expert climatologists are always required. So private Architectural farms too require Climatologist.
Jobs in State and Central Agricultural Universities.
Indian Council of Agricultural Research
Indian Space Research Centre.
National Remote Sensing Agency.
Department of Science and Technology.
Space Application Centre.
Apart from these, there are international jobs for a meteorologist. For these the student has to keep himself updated in latest career trends and job market.
Meteorologist salary in India:
Meteorologist salary will be according to the organization he works. If he works in State run offices he will be paid according to state pay scale. The Organizations like Indian Meteorogical department, Indian Space Research Centre and other central govt departments jobs in Meteorology will be according to Pay commission scale. So, a meteorologist can expect good salary as well as job security in India.
All the best.

Hi Rohith,
First of all, you have to study advanced physics and mathematics. Now, you can either sit in competitive exams and get a good rank, or pursue higher education in reputed institutes until you get a Ph.D. Your current course won't be an obstacle. By first year, I think you mean intermediate or class XI. If yes, then it's perfect. If you mean B.Sc., then it's still cool, you have a lot of time left.
Having a creative mind and good grip on subjects of astrophysics, particle physics, quantum mechanics, cosmology, and basic Newtonian physics will be very helpful. For that, I would recommend reading books on the subject. I'm going to give a recommendation list in the end.
Don't think that only good numbers, good ranks, or tags of top institutes can make you an astrophysicist. There are many research centres and organisations, even ISRO, who don't take these criteria too seriously.
Believe in yourself. If you have the brain of an astrophysicist, you will be recognised just with good knowledge, good percentage, and interest. No need for excellent marks.
It's a very technical field, and I'm myself very interested in this, so I would recommend having a good grasp on interesting topics like string framework, spacetime, nothingness, symmetry, inflation, entropy, etc. After this, make sure you have enough qualifications and marks. You'll have to pay attention to supplementary subjects like maths because they can dampen your overall prospects.
Recommended books:
The Fabric of the Cosmos by Brian Greene: must read, general-level, would explain most complicated topics with the least hassle like about time, quantum mechanics, inflation, etc.
Stardust by John Gribbin: a very beautiful book that's more literature than Science.
A Brief History of Time by Stephen Hawkins: somewhat advanced but needed once you're serious about being an astrophysicist.
You might also try The Theory of Everything and An Elegant Universe.
I hope this helps.
All the best.

Hi Baban,
The centrifugal force, which is the outward pull of the ball on its string, is the centrifugal force. Also, there is general appreciation of the fact that the amount of this force can be increased by increasing either the angular velocity of rotation, the mass of the object, or the radius of the circle through which the object moves. Perhaps not so generally appreciated is the fact that, whereas the centrifugal force is directly proportional to the radius and to the mass, it is proportional to the square of the angular velocity. For example, doubling the mass of the rotating object will increase the centrifugal force by a factor of 2, but doubling the number of revolutions per minute (rpm) will increase the centrifugal force by a factor of 4 (equals 2 times 2); similarly, increasing the speed by a factor of 10 will increase the force by a factor of 100 (equals 10 times 10). Centrifugal force is expressed by the basic relation F = m2 / R = 42mn2R; F is the centrifugal force, m the mass, R the radius, v the speed, and n the number of revolutions per second.
All the best.

Hi Himanshu,
In order to become a successful archaeologist, you may choose any stream in class 11th and 12th as the doors to enter the field will be wide open for you. After completing class 12th, in this regard, the first step towards becoming a successful archaeologist is to obtain a graduate degree. This could be in any discipline. However, it is preferable to have a Bachelors degree in history, sociology, or anthropology for a better understanding of the concepts of archaeology. Further, it is advisable to check with the concerned university what all Bachelors degrees are acceptable for taking up a postgraduate course in archaeology.
However, universities like the Maharaj Sayajirao University of Baroda, offers a three years Bachelors degree in Indian History, Culture and Archaeology. Similarly, the Banaras Hindu University, offers two undergraduate courses in this field: a three years honours program in Ancient Indian History, Culture and Archaeology and a three years vocational program in Museology and Archaeology.
The Institute of Archaeology under the aegis of Archaeological Survey of India (ASI), New Delhi, conducts a two year Post Graduate Diploma in Archaeology. The eligibility of entry to this program includes a Masters degree in Ancient or Medieval Indian History, Anthropology, or Archaeology form a recognized university. Students holding a Masters degree in classical languages or geology can also apply for this program.
The practical test in itself comprises of the following sections: Surveying, Drawing, Photography, Modelling, Exploration & Excavation, Chemical Conservation, Computer Application, Viva-voce, General observations, Tutorials, and a Dissertation.
After completing the post graduation level, candidates can opt for higher studies. They can either go for a doctorate degree or take up lectureship in a university after qualifying the norms laid down by the University Grants Commission (UGC) in this regard. From the Masters level onwards, candidates can look for suitable career opportunities either in the teaching line or as an archaeologist employed with the ASI at the central or at the state level.
All the best.

Hi Chanchal,
Well, first of all, you can't get something for nothing. The work electricity can do is measured in watts. Light a bulb, run a microwave, a hair dryer, whatever. And watts are calculated using Ohms Law:
E (volts) times I (current) = P (power, in watts). So, for a given amount of power, if E goes up, I must go down.
Transformers pass current by the primary generating a magnetic fiel, which induces a current and voltage in the secondary. You can step up, down, or neither voltage.This is accomplished by having a different number of windings on the primary and secondary coils. If the number of turns on the coil in both primary and secondary coils is the same , the voltage and current on both sides will be the same, minus the loss incurred across the transformer. Commercial transformers are very efficient, upwards of 95%.
If the windings on the secondary are twice as many as on the primary, the voltage will double, the current will halve.
I hope it's clear.
All the best.
