Students in Grade 13 had the second-highest depression and anxiety scores, with examination-related issues being the most commonly cited problem. Of the 445 students assessed, 22.9% of Grade 12 students and 28.6% of Grade 13 students reportedly had severe depression , while 28.6% of Grade 12 students and 32.1% of Grade 13 students experienced ...

The second moment of area, also known as area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with respect to an arbitrary axis. The unit of dimension of the second moment of area is length to fourth power, L 4, and should not be confused with the mass moment of inertia.
Refraction of light at the interface between two media of different refractive indices, with n 2 > n 1.Since the velocity is lower in the second medium (v 2 < v 1), the angle of refraction θ 2 is less than the angle of incidence θ 1; that is, the ray in the higher-index medium is closer to the normal.
Circular orbits are possible when the effective force is zero: = = [+] =; i.e., when the two attractive forces—Newtonian gravity (first term) and the attraction unique to general relativity (third term)—are exactly balanced by the repulsive centrifugal force (second term).
A number of different units of measurement were used in Sri Lanka to measure quantities like length, mass and capacity from very ancient times. [1] Under the British Empire, imperial units became the official units of measurement [2] and remained so until Sri Lanka adopted the metric system in the 1970s.
The test is taken during the first half of April each year by approximately 10,000 physics students. [1] Competitors must attempt 40 physics-related multiple choice questions in a 45 minute long time period. First-year physics students take the Division I test, while second-year physics students take the Division II test. [1]
Zahira College (commonly known as Zahira) (Sinhala: සහිරා විදුහල, Tamil: சாஹிரா கல்லுரி) is an Islamic school in Maradana, Colombo, Sri Lanka, founded in 1892 as Al Madrasathul Zahira by Islamic lawyer and educationalist, M. C. Siddi Lebbe, with the patronage of Ahmed Orabi Pasha of Egypt.
