Hello,

Hope you are doing great.

Answering to your question ,

Preparing for AP ECET involves understanding the exam pattern and reviewing the syllabus thoroughly. Practice previous year papers and take mock tests to assess your preparation level and improve time management skills. Focus on building a strong foundation of concepts in all subjects and allocate time for revision before the exam. Stay updated with any changes in the exam pattern or syllabus. By following these strategies consistently, you can effectively prepare for the AP ECET and increase your chances of success.For more information kindlyb got thropgh the link mentioned below: AP ECET Exam Pattern 2024: Qualifying Marks, Marking Scheme, Total Marks, Duration (careers360.com) AP ECET Mock Test 2024 (Released) - Free Practice Paper Here (careers360.com)

Hello Aspirant,

The posted universities are bigger and offer every course for application. You can select the course and then select the better  universities accordingly. Through placement rate, fee structure and other factors. These can be better options for any course.

ALL THE BEST

Hello,

Magnetic induction, also known as magnetic flux density or magnetic field strength, is a measure of the strength of a magnetic field at a particular point in space. It is represented by the symbol B and is measured in units of tesla (T).

Magnetic induction describes the density of magnetic field lines passing through a given area perpendicular to the direction of the field. The higher the magnetic induction, the stronger the magnetic field. It plays a crucial role in various applications, such as electromagnetism, magnetic materials, and electrical devices.

Hope this helps,

Thank you

Hi reader ,

The parallel axis theorem states that, the moment of inertia of a body about any axis is equal to the moment of inertia about parallel axis through its center of mass plus the product of the mass of the body and the square of the perpendicular distance between the two parallel axes.

If the moment of inertia known for axis through center of gravity of object and want instead of center the moment of inertia at the edge. Can use the parallel axis theorem to find that instead of reworking everything from the new axis.

i hope this helps

thank you

Dear Aspirant, since Y-chromosome possesses small amount of euchromatin that contains DNA or genes, therefore it is genetically less active. Recent research has shown that the Y chromosome has developed some pretty convincing mechanisms to "put the brakes on", slowing the rate of gene loss to a possible standstill. I hope you are clear now. If you have any other doubts feel free to ask. All The Best!!!

We know that the current that the electron will be emitting when it is in it's original state is e/T, or which is ev/(2*pi*r).

So, the field at the centre will be (mu*e*v)/(4*pi*r^2) = B.

Now, from this relation we can easily observe that B is inversely proportional to n^3. So, if the electron jumps from n=1 to n=2, then the magnetic field will reduce by a factor or 2^3 or 8. So, the new field is B/8.

Dear Student,

The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object . It is defined as the inverse of the distance or angular separation between two objects which can be just resolved when viewed through the optical instrument.

The resolving power of an optical system is ultimately limited by diffraction by the aperture. Thus an optical system cannot form a perfect image of a point.

Resolving Power of Telescope :

In telescopes, very close objects such as binary stars or individual stars of galaxies subtend very small angles on the telescope. To resolve them we need very large apertures. We can use Rayleigh’s to determine the resolving power. The angular separation between two objects must be

θ = 1.22 λ/d  and Resolving power = 1/θ = d/1.22 λ

Thus, the higher the diameter d, the better the resolution. The best astronomical optical telescopes have mirror diameters as large as 10 m to achieve the best resolution. Also, larger wavelengths reduce the resolving power, and consequently, radio and microwave telescopes need larger mirrors.

Resolving Power of Microscope :

For microscopes, the resolving power is the inverse of the distance between two objects that can be just resolved.

d = λ/2 n sin θ

Resolving power = 1/ d = 2n sin θ/ λ

Where n is the refractive index of the medium separating object and aperture. Note that to achieve high-resolution n sin θ must be large. This is known as the Numerical aperture.

Happy Learning!
