Universal extra dimension, proposed and first studied in 2000, assume, at variance with the ADD and RS approaches, that all fields propagate universally in extra dimensions. Multiple time dimensions , i.e. the possibility that there might be more than one dimension of time , has occasionally been discussed in physics and philosophy, although ...
The fourth quadrant also has Frequently Asked Questions (FAQs) and their answers to clarify common misconceptions among students. [ 10 ] The University Grants Commission (UGC) considers that universities should play a key role in publicizing and popularizing SWAYAM courses among their learners and the university, enabling them to gain from ...
Question 21 requires comparing two social objects or phenomena (indicating two similarities and two differences). Question 22 is a matching task. Questions 23 and 24 test the ability to work with statistical materials (diagrams or tables). Question 25 assesses the ability to distinguish evaluative judgments from factual statements.
