What is the radius of the first Bohr orbit in He+? The radius of first Bohr orbit of hydrogen atom is 0.529 A. What is the radius of the third orbit of He+? the basic formula for calculating the radius of nth orbit is Rn=0.529×(n^2/Z)angstrom where Z is the atomic number of the element. What […]
What is the most dangerous mutation?
What is the most dangerous mutation? Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. What are examples of […]
Can I take a picture of something and you tell me what it is?
Can I take a picture of something and you tell me what it is? The Google Goggles app is an image-recognition mobile app that uses visual search technology to identify objects through a mobile device’s camera. Users can take a photo of a physical object, and Google searches and retrieves information about the image. How […]
What is the magnitude of a displacement?
What is the magnitude of a displacement? Magnitude of displacement is equal to the absolute value of the displacement vector. In physical sense, the magnitude of displacement is equal to the linear distance between initial and final positions along the straight line joining two positions i.e. the shortest distance between initial and final positions. Does […]
What is the adiabatic equation?
What is the adiabatic equation? The normally used equation is the so-called adiabatic equation. For a given fault of I, which lasts for time t, the minimum required cable cross-sectional area is given by: A=√I2tk. where: A – the nominal cross-section area, mm2. I – the fault current in, A. What is work done in […]
What is the typical size of magnetic domains?
What is the typical size of magnetic domains? 0.1 to 1 mm How do you align magnetic domains? Use the Magnet Position slider to move the magnet closer to the ferromagnetic material so that it interacts with the field lines. As you repeat the process, you’ll notice the domains gradually aligning – with the field […]
What are the limits of mathematical models?
What are the limits of mathematical models? It is difficult to represent real-world systems in terms of mathematical relationships. Data are often unavailable or inaccurate. Combining the sub- system models to create the model is seldom simple. Assumptions and estimates must be made at almost every step of the process. What is the meaning of […]
What are the 10 most common food allergies?
What are the 10 most common food allergies? The 10 Most Common Food Allergies Peanuts. Soy. Wheat. Tree Nuts. Shellfish. Fish. Raw Fruits and Vegetables. Sesame Seeds. Put down the everything bagel — one seed on your favorite breakfast treat could cause a boatload of allergenic symptoms. Does food intolerance involve immune system? Food intolerance […]
Does a proton have a magnetic field?
Does a proton have a magnetic field? Protons and neutrons, both nucleons, comprise the nucleus of an atom, and both nucleons act as small magnets whose strength is measured by their magnetic moments. The magnitude of the proton’s magnetic moment indicates that the proton is not an elementary particle. Why is the trajectory of the […]
What will eventually happen to the concentration of particles inside and outside the cell?
What will eventually happen to the concentration of particles inside and outside the cell? If the number of particles inside the cell is higher than the number of particles outside of the cell a hypotonic system has been established. Again the water molecules move more easily than the particles inside the cell. With the concentration […]
