Does gravitational force increase with distance?

Does gravitational force increase with distance? Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. What happens to the […]

How do you find the Hamiltonian system?

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 the most important factor in soil formation?

Is the most important factor in soil formation? Climate: This is probably the most important factor that can shape the formation of soils. Two important climatic components, temperature and precipitation are key. They determine how quickly weathering will be, and what kind of organic materials may be available on and inside of the soils. Which […]

What are the 2 types of cardiovascular fitness?

What are the 2 types of cardiovascular fitness? Cardio training increases the function, capacity, and health of the heart and lungs. There are basically two types of cardio training: aerobic and anaerobic. Is too much cardio bad for your heart? But two new studies published in the journal Heart suggest doing too much high-intensity exercise […]

How do key beds help date rock layers?

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 […]

Is 70 kg a good weight?

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 […]

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 […]

What is the principle of optical Fibre?

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 […]
