Hello friends!
Do you have some doubts in Physics which you always wanted to ask, but could never do?
Don’t fear, don’t hesitate!
Only those questions are foolish, which are not asked!!!
Ask your doubts on Fundamental Physics here!
Your questions will be responded on the basis of the genuinity of the questions. Don’t post your home work questions here. This is not Home Work Help. We welcome the genuine doubts arising as a result of curiosity and deep thinking.
It has become a practice among many students (compared to a few decades back) to read only what is taught the day and not what happened before.
Though it is a good practice to start with current topic, revising back to the beginning as much as possible is very much helpful in performing well in exams. Every time you repeat, the mind seeks new meanings and interpretations and this becomes helpful while answering the HOTS questions (If you have the determination to answer every question to the best of your ability & beyond!) When we read again and again new questions related to the topic arises in our mind and the effort to answer the questions is the beginning of true learning. Only when you read with an active, curious and questioning mind, learning becomes effective.
And don’t rest until you find satisfying and convincing answers to your questions… The answers, the explanations and the logical reasoning developed by you will last forever. But always discuss those with a good teacher. Sometimes it happens that the explanations developed by oneself has some faulty considerations and may be violating the basic principles of conservation or some other of the sort.
AISSCE Physics (Class 12 CBSE Physics) question paper 2018 was found difficult by most of the students. Post your reactions here. Your feedback may help the evaluators to understand your difficulties and include them while evaluating the papers.
I have used this idiomatic expressions which means being in friendly terms with both parties in a quarrel as the title of my post purposefully. A quarrel ensues when two parties find it difficult to reach a rapprochement over an issue concerning them .But the dismaying fact is that certain issues have inherent in them ,an enigmatic combination of thesis and antithesis. One such is the topic of the desirability of exams in Schools and Colleges.
Given the nature of this topic, I will hold an ambivalent approach to it. In other words,I will run with the Hare and hunt with the hounds. The teacher in me believes that exams are an integral part of teaching-learning process and exam should follow a certain amount of teaching- learning .The argument is that examinations are the tools , tailor -made for quantifying and evaluating the learning outcomes. Exam result provides the teacher with ample feedback on the academic status of the students .This feedback can subsequently used for the follow up.
The more liberal teacher in me holds a different standpoint. His voice is the echo of the agonized cry of a student who has become a beast academic burden and who struggles to keep pace with the curricular indoctrination that is done in distinct packages in every period .Things come out of the woodwork in each teaching period and an average student starts goofing up things .This pitiful child feels out of place. But Brutus is an honourable man.
There is no denying the fact that we can’t do away with examinations because there is no other effective alternative. Very often , absence of choices rule the roost. The only thing that we can do is to get our children better equipped for these exams that have become certitude in the life of a student so that he will feel relieved from the smothering exam syndromes.
Wishing tension -free exam days to the student fraternity.
Everyone wants to pass exam – especially when it comes to Board Exams. Many enjoyed the entire year in company with friends from the class and outside. Now the exam fever is on and some are finding it difficult to get pass marks and Physics is the one subject many find it difficult to mug up in a hurry. So, here we have come up with a sure shot method to succeed. If you are ready to work hard, you can score more than 50% marks with the method we suggest. But you should strictly follow the schedule.
Step #1
Make a strong determination and say aloud “I will Pass Exam”
Your decision and determination will work more than anyone else’s. The first step towards to success is to believe that you can do it and be ready to work for it irrespective of the hardships and troubles you may face during the course. Put a reminder at a visible place so that you’re always reminded of your decision to pass exam. Go to next page
Nicholas James is a motivational speaker from Australia. Born with phocomelia, a rare disorder characterised by the absence of legs and arms. As a child, he struggled mentally and emotionally as well as physically, but eventually came to terms with his disability. He presents motivational speeches worldwide which focus on living with disabilities and finding hope and meaning in life.
Vujicic asked his parents when he was aged 13 about his birth. Several days before he was born, there was no notification from a doctor or nurse that something was wrong. However, when he was born his mother asked a nurse how the baby was and there was a silence among the nurses. When his mother persisted and asked a doctor what had happened with the baby, he said “phocomelia”. As his mother worked as a paediatric nurse in charge of a delivery room, she immediately knew what the medical term meant. At first, she refused to see him or hold him when the nurse had him in front of her, but she and her husband tried to accept it and tried to understand God’s plan for their son through a strong faith in God
Even though his mother gave him a cushion to support himself, he overcame and taught himself how to stand up with a method by leaning his forehead over the wall and slowly standing up. Originally, he was born with combined two toes, so he could use them for rolling over, shoving and bracing himself. Because of this, his parents and doctor decided to have an operation to separate his toes so that he could use them as fingers to grab, turn pages and other functions. Even though the operation did not go as well as the doctor wanted, he tried to adapt using these freed toes and with the help of an electronic wheelchair, computer and mobile phone became more free.
After his mother showed him a newspaper article about a man dealing with a severe disability when he was seventeen, he started to give talks at his prayer group and later founded his non-profit organisation, Life Without Limbs.
He concludes that his childhood was an “amazingly normal childhood” and he advises readers to not give up, to change their circumstances if needed and to stop their concerns about whether their luck will be better and run after any desire.
CBSE Physics Class XII Important diagrams from Electromagnetic Induction and AC can be downloaded here.
The students should note that the diagrams are to be as per the text books and therefore we have taken care to follow the text book in preparing the files.
The following diagrams are included in the file
ELECTROMAGNETIC INDUCTION
Faraday’s Experiment on Electro Magnetic Induction
Download the collection of diagrams from the chapter Magnetic Effects of current from the link below. Cyclotron and Moving Coil Galvanometer seems to the most important topics here. Conversion of galvanometer to ammeter and voltmeter is also to be given due weightage. Remember, the importance of a radial magnetic field in MCG (Moving Coil Galvanometer) is a frequently asked question in CBSE.
There are a lot of circuit diagrams and other diagrams to be practised from the chapter current electricity. The essential diagrams are prepared in the following file for ready use. You may take a printout of the file for practice.
When you draw the diagram, don’t draw freehand diagrams. Use geometrical instruments and pencil. The diagram should be neat and perfect. At the same time, you should not be consuming lot of time in perfecting the diagrams at the cost of answers to other questions.
In order to draw diagrams perfectly consuming very less time, it is necessary to practise all the diagrams well in advance. the file given below is a collection of all diagrams from the chapter current electricity as per the NCERT textbook.
