Physics Spl

With an 86.5% in HSC boards and 95% in PCM, you have a strong chance of getting into St. Xavier's College for a BSc in Physics, especially if you're not in the general category. 

Here's a more detailed breakdown:

St. Xavier's College, Mumbai:

Admission is based on merit scores in the qualifying examination. 

HSC Boards:

An 86.5% overall score is a good starting point, but St. Xavier's is highly competitive, especially for Science courses. 

PCM Subjects:

A 95% average in Physics, Chemistry, and Mathematics significantly strengthens your application. 

In Physics, Power is the rate at which work is done or energy gets transferred per unit time. It is expressed by the following formulae:

P stands for power, W is for work, t is for time. Power is measured in unit Watt (W) where 1 watt = 1 joule per second. Another unit which is commonly used to measure the power is horsepower (hp), 1hp =746 W.
Power at a specific moment is instantaneous and over a period it is average. 

The work-energy theorem in Physics Work, Energy and Power refers to that net work done on an object is equal to its change in kinetic energy. The following is the formula:

Work-energy theorem means that when work is done on an object, the object gains kinetic energy and when an object does the work, it loses kinetic energy. This theorem helps in solving problems related to motion and forces without directly using kinematic equations. It is especially useful in conservative and non-conservative forces cases and it helps in simplifying complex motion analysis.

Energy in Physics means the ability to do work and it can exist in different forms:

• Kinetic Energy (? ) – It is the energy of a moving object. The formulae are KE=1/2mv2
• Potential Energy (PE) - It is stored energy due to position. Formulae are PE=mgh for gravitational potential energy.
• Mechanical Energy - Total of KE and PE.
• Thermal Energy - Energy generated due to heat.
• Chemical Energy - Energy stored in chemical bonds.
• Nuclear Energy - Related to atomic nuclei.
• Electrical Energy - Related to electric charges.

Your books provide a strong foundation, but for JEE Mains, you need more problem-solving practice. Add HC Verma (Physics), Arihant/Cengage (Maths), and P. Bahadur (Physical Chemistry), along with mock tests for better preparation.

Students need to successfully complete their Class 12 year with Physics along with both Chemistry and Biology/Biotechnology together with English to become eligible for NEET admission. Candidates who fall into the General category must achieve a minimum of 50% marks in PCB yet General-PWD applicants need 45% marks and SC/ST/OBC candidates must demonstrate 40% marks. The percentage of NEET marks depends on your category while your total PCB score amounts to 167. Students within the SC/ST/OBC category should consider taking the NEET examination whereas those from the General category will have to reevaluate their candidacy.

Students can get access to the NCERT Solutions for Class 12 Chapter 8 Electromagnetic Waves in PDF by visiting the Shiksha homepage related to the Ch 8 Electromagnetic Waves and then click on the "Class 12 Alternating Current Chapter NCERT Solution PDF: Download PDF for Free," and then donwload free PDF.

These NCERT PDFs are helpful for students to improve their exam preparation, understanding of important and difficult concepts and to do their revision before exam. 

Here are some o the points for candidates to focus on while preparing for the Class 12 Physics Ch 8 Electromagnetic Waves:

• Focus on understanding Maxwell's equations.
• Understand the role of displacement current.
• Comprehend the practical applications of electromagnetic waves.
• Solve numerical problems and refer to NCERT Solutions for Class 12 Physics PDF for the detailed explanations. 

The Class 12 Physics Chapter 8 Electromagnetic waves consists of some of the important topics that can be asked in the CBSE Board exams and other competitive exams. Therefore, it is necessary for candidates to follow up with these important topics such as Electromagnetic waves properties, Maxwell's equations, displacement current, and the electromagnetic spectrum. These waves are used for real-world applications like communication systems, medical imaging, and remote sensing.
