Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
The majority of candidates enter the exam through their respective schools, but those who have completed their school education can also apply as private candidates. The qualification also serves as an entrance requirement for Sri Lankan state universities. The exams are offered in three mediums: Sinhala, Tamil, and English.
The preliminary round of the Sri Lankan Astronomy and Astrophysics Olympiad competition is a two-hour theory paper on Astronomy and Astrophysics. [2] It usually consists of 20-30 multiple choice questions and five structured essay type questions. The competition is conducted in three languages Sinhala, Tamil and English.
The concept of establishing the Open University of Sri Lanka was by Dr. Nissanka Wijeyeratne the Cabinet Minister of Education & Higher Education at the time. [3] [4]As Cabinet Minister of Education and Higher Education, [5] Wijeyeratne introduced the Universities Act No 16 of 1978 to Parliament. [3]
g is the gravitational acceleration [m/s 2] Requiring the force balance F d = F e and solving for the velocity v gives the terminal velocity v s . Note that since the excess force increases as R 3 and Stokes' drag increases as R , the terminal velocity increases as R 2 and thus varies greatly with particle size as shown below.
The newton-second (also newton second; symbol: N⋅s or N s) [1] is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second.

The exams are held in three mediums Sinhala, Tamil and English. The exam is the basic Certificate awarded in Sri Lanka as proof of completion of Secondary Education. The GCE O/L examination is an important milestone for students as it determines their eligibility to pursue further studies at the Advanced Level (A/L) or vocational training courses.
