FAQs on JEE Main 2014 April 9th Shift 1 Physics Question Paper with Answer Keys and Solutions
1. What books should I refer to and study from for JEE Main Physics?
One can easily refer to JEE Physics study materials from vedantu. Vedantu provides chapterwise solutions for the JEE Main and Advanced. For, Optics and Modern Physics, Understanding Physics: OPTICS & MODERN PHYSICS by DC Pandey and Cengage Physics for JEE (Advanced): Optics & Modern Physics by BM Sharma but could also look at the brilliant notes that Vedantu provides (Read Vedantu’s recommended books for preparation here).
One of the keys to breaking JEE is to complete mock tests however much as could reasonably be expected. It provides you with the possibility of the assessment just as how long you really want to isolate for every subject. The more derides you solve the better are your odds of coming to an IIT or any foundation that you have as a primary concern.
2. What sub-topics will come under Oscillations and Waves for JEE Mains?
The sub-topics that come under Oscillations and Waves are Periodic motion – period, frequency, displacement as a function of time. Periodic functions. Simple harmonic motion (S.H.M.) and its equation; phase; oscillations of a spring -restoring force and force constant; energy in S.H.M. – Kinetic and potential energies; Simple pendulum – derivation of expression for its time period; Free, forced and damped oscillations, resonance.
In the case of Wave motion, Longitudinal and transverse waves, Speed of a wave. Displacement relation for a progressive wave. Principle of superposition of waves, the reflection of waves, Standing waves in strings and organ pipes, fundamental mode and harmonics, Beats, Doppler effect in sound.
3. What should one study while preparing for Properties of Solids and Liquids?
In the unit Properties of Solids and Liquids, one should prepare Elastic behavior, Stress-strain relationship, Hooke’s Law, Young’s modulus, bulk modulus, modulus of rigidity. Pressure due to a fluid column; Pascal’s law and its applications. Viscosity, Stokes’ law, terminal velocity, streamline and turbulent flow, Reynolds number.
Bernoulli’s principle and its applications. Surface energy and surface tension, angle of contact, application of surface tension – drops, bubbles, and capillary rise. Heat, temperature, thermal expansion; specific heat capacity, calorimetry; change of state, latent heat. Heat transfer-conduction, convection, and radiation, Newton’s law of cooling and so much you can find on the official Vedantu site/app with revision notes too.
4. What is current electricity and how should one study for it for JEE Mains exams?
Current Electricity holds the maximum weightage of 10% and Current Electricity is the pace of charge flows through any cross-segment, for example, I = dq/dt.
The heading of the development of positive charge is routinely considered as the bearing of electric flow. It is a scalar amount and the S.I. Unit is Ampere (A).
Current conductor transporters are electrons, (valence e – s) electrolyte particles, semiconductor electrons and openings, and positive particles or electrons in gases.
Charge of electron = 1.6 × 10–19c
1 ampere = 6.25 × 1018 electrons/sec.
A student can easily Refer to these notes that are available on the Vedanta app and can work his way through. Current electricity is a very important topic for JEE Mains preparation because it sets the base for other chapters as well and helps a student understand other complex problems that will further come in the chapters. Vedanta provides you with revision notes and presentations along with LIVE classes that a student can attend and learn all about current electricity.
