How do you find the Hamiltonian system? For many mechanical systems, the Hamiltonian takes the form H(q,p) = T(q,p) + V(q)\ , where T(q,p) is the kinetic energy, and V(q) is the potential energy of the system. Such systems are called natural Hamiltonian systems. How do I know if my Hamiltonian is Hermitian? The kinetic […]

Is 70 kg a good weight? According to BMI chart and their classification, BMI score of 22.86 for 70 kilograms weight & 175 cm tall indicates that your weight is Normal. The Body Mass Index of 22.86 is derived from the weight of 70 kilograms divided by the square of height 175 centimeters. Is 70 […]

What holds nucleus together? strong nuclear force Which element has the most stable nucleus in the universe? Iron 56 Which is the least stable nuclide? Elements with atomic number less than 83 have at least one stable isotopes except technetium (Tc, Z = 41) and promethium (Pm, Z = 61). Why is s 32 A […]

How do key beds help date rock layers? Like index fossils, key beds are used to match rock layers. A key bed is a thin layer of rock. The rock must be unique and widespread. For example, a key bed from around the time that the dinosaurs went extinct is very important. What is biostratigraphy […]

What is the principle of optical Fibre? Optical Fibers are based on Total Internal Reflection. The phenomenon in which the angle of incidence is more than the critical angle is known as total internal reflection. What are the properties of optical fiber? The most important properties for communications are attenuation, light collection and propagation, fiber […]

What is the focal length of concavo-convex lens? The focal length of a concave-convex lens of radii of curvature 5 cm and 10 cm is 20 cm. Why power of convex lens is positive? Answer. The power of a convex lens is positive as a convex lens has a positive focal length, while the power […]

Which is the best example of potential energy? Potential energy is the stored energy an object has because of its position or state. A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy. What are two examples of kinetic and potential energy? What Are […]

What are 5 types of catapults? There are five historical types of catapults: the mangonel, onager, ballista and trebuchet, using three types of motive force: tension, torsion and gravity. Side view of a torsion powered mangonel catapult in the cocked position. What angle is best for a catapult? 45-degree angle How far can a catapult […]
