NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT
Since potential energy is derived from work, it is also a scalar quantity. 3. Conclusion: - Among the quantities analyzed, potential energy is the only one that does not possess both magnitude and direction. Therefore, it is not a vector quantity. Final Answer:The quantity that is not a ...

However, since these eigenvalue-based methods are scalar-valued, many researchers and textbooks accepted that vorticity is vortex. In recent years, Dr. Liu developed a new vortex identification method called Luitex. Liutex is a vector quantity with a clear physical meaning that overcomes the ...
In the above, vectorband scalarpare to be estimated. This model commonly arises in a random-effects context. One assumes that u_it = v_i + e_it (3) where v_i are fixed constants within panel and e_it are independent. The random-effects equation (3) implies a constant correlation mat...

Footnote9 In the case of a 1-factor model (k=1), f⁁ is a scalar (a single score for each person), whereas y is a vector of p observed variables, so W reduces to a 1×p row vector of optimal weights for each variable. For multi-factor models, each row of W gives optimal ...
It is often more convenient to work with the angular momentum parameter a=J/M. The evolution of Kerr black holes under Hawking evaporation is straightforward – they spin down. It is true that if a Kerr black hole only emits scalar particles, it will evolve towards a/M≈0.555, however ...
The plant maintenance respiration is calculated as a function of leaf nitrogen, air temperature, and previous biomass 𝐶𝑖−1Ci−1. 𝑟10r10 is the plant tissue respiration rate at 10 °C; cn stands for plant carbon-to-nitrogen ratio; 𝜎𝑖σi is a scalar that modifies the ...
