What is C in binding energy? 12 C. This is the mass of the carbon atom, i.e. the mass of the nucleus plus the six electrons in the neutral carbon atom. Let’s calculate its binding energy. Why heavy nuclei are unstable? The presence of too many protons and neutrons in heavier nuclei will upset the […]
Which quality is rotating at a constant angular velocity?
Which quality is rotating at a constant angular velocity? The angular velocity is defined as the rate of change in the angular position of a rotating object. It is rotational equivalent to the linear velocity. It is measured in rad/sec in the SI unit system. How do you find the constant angular acceleration? For a […]
Which color is not a primary color of light?
What are the two basic principle of electromagnetism?
What are the two basic principle of electromagnetism? Electromagnetic survey methods are based on two fundamental principles: Faraday’s law of electromagnetic induction and the fact that electric currents generate magnetic fields, expressed in Ampère’s law. What are the properties of magnetism? Magnets exhibit the following properties: All magnets have two poles: the North Pole and […]
What are the characteristics of sensory receptors?
What are the characteristics of sensory receptors? Sensory receptors that share a common location often share a related function. Sensory receptors code four aspects of a stimulus: modality (or type), intensity, location, and duration. Cutaneous touch receptors and muscle spindle receptors are both mechanoreceptors, but they differ in location. Which type of cell is sensory? […]
What is the only Fsii additive approved for turbine fuels?
What is the only Fsii additive approved for turbine fuels? Innospec’s FSII-41 ice inhibitor is based on Di-Ethylene Glycol Monomethyl Ether (DiEGME) chemistry, the preferred solution for today’s market. The additive is suitable for use in either aviation turbine fuel (jet fuel) or aviation gasoline, subject to specification requirements and approvals. What is Prist made […]
Which of the following describes a qualitative study?
Which of the following describes a qualitative study? It describes and answers questions about participants and contexts. It explores a phenomenon to better understand it. It answers questions and illuminates issues that cannot be answered by quantitative methods. Qualitative research can provide understanding of a particular setting or contextually relevant situation. What is qualitative data? […]
What is the minimum energy needed to ionize hydrogen atom when it is in the N 2 state?
What is the minimum energy needed to ionize hydrogen atom when it is in the N 2 state? Minimum energy needed to ionize an electron from 2nd Bohr orbit of hydrogen atom is 5.45×10−19 J/atom. How much energy would it take to remove an electron from hydrogen? For a hydrogen atom, composed of an orbiting […]
How can we save water at home and school?
How can we save water at home and school? Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other similar waste in the dustbins rather than the toilet. Landscape with native, drought tolerant plants, and mulch regularly. Raise awareness of the importance of water by creating colorful posters on water use and water saving. […]
Why linear regression is called linear?
Why linear regression is called linear? Given a data set of n statistical units, a linear regression model assumes that the relationship between the dependent variable yi and the p-vector of regressors xi is linear. The model remains linear as long as it is linear in the parameter vector β. Why is regression linear? Simple […]
