What element has an oxidation number of 1+? hydrogen What is the oxidation number of Na? +1 What is the oxidation number for NO3? In the NO3- ion, each oxygen is assigned an oxidation state of -2. Since N-6 = -1, the oxidation state of nitrogen in NO3- will be +5. What is the difference […]
What forces act on the bullet being dropped and the bullet being shot?
What forces act on the bullet being dropped and the bullet being shot? There are no horizontal forces acting on it and it only experiences the downward acceleration of earth’s gravity. The correct answer is not quite, since there are complex lift and drag forces on the moving bullet. Generally the fired bullet will land […]
What is the vision input system?
What is the vision input system? Computer vision is the science and technology of machines that see. This type of processing typically needs input data provided by a computer vision system, acting as a vision sensor and providing high-level information about the environment and the robot. What is vision input system How does it work? […]
Is curl a vector?
Is curl a vector? In vector calculus, the curl is a vector operator that describes the infinitesimal circulation of a vector field in three-dimensional Euclidean space. The curl of a field is formally defined as the circulation density at each point of the field. A vector field whose curl is zero is called irrotational. What […]
How can you tell if its a satellite?
How can you tell if its a satellite? Watch the sky closely in the dawn or dusk hours, and you’ll likely see a moving “star” or two sliding by. These are satellites, or “artificial moons” placed in low Earth orbit. These shine via reflected sunlight as they pass hundreds of kilometres overhead. Can I see […]
What is the SI unit and dimensional formula of angular momentum?
What is the SI unit and dimensional formula of angular momentum? What is Angular Momentum? Symbol The angular momentum is a vector quantity, denoted by \vec{L} Units It is measured using SI base units: Kg.m2.s-1 Dimensional formula The dimensional formula is: [M][L]2[T]-1 What is the dimensional formula of frequency of vibration? Therefore, frequency is dimensionally […]

Who named the electron?
Who named the electron? G. Johnstone Stoney How did they discover the electron? In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas. What did E Goldstein discover? Eugen Goldstein […]
