How do you represent elevation? Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface. How do […]
How many molecular orbitals will have an N value of 2?
How many molecular orbitals will have an N value of 2? Explanation: The atomic orbitals with an n value of 2 are the 2s orbital and the three 2p orbitals. When these four orbitals from one atom interact with four orbitals from another atom, they generate 8 molecular orbitals, half of which will be bonding […]
How does experience affect our perception?
How does experience affect our perception? Past Experiences and Education What you perceive is strongly influenced by your past experience, education, culture, values and other factors. All these influences predispose you to pay particular attention to certain information and to organize and interpret the information in certain ways. Has any of your past experiences affect […]
Why is my diastolic pressure high?
Why is my diastolic pressure high? A: A high diastolic blood pressure (80 mm Hg or higher) that stays high over time means you have high blood pressure, or hypertension, even when systolic blood pressure is normal. Causes of diastolic high blood pressure include both lifestyle factors and genetics, but the disease is multifactorial. Why […]
Is heat equal to change in enthalpy?
Is heat equal to change in enthalpy? At constant volume, the heat of reaction is equal to the change in the internal energy of the system. At constant pressure, the heat of reaction is equal to the enthalpy change of the system. What is flow and non flow process in thermodynamics? Non flow process: It […]
Which correlation is the weakest?
Which correlation is the weakest? Strength – The weakest linear relationship is indicated by a correlation coefficient equal to 0 (actually this represents no correlation!). The strongest linear correlation is indicated by a correlation of -1 or 1. What is considered a low correlation? Moderate degree: If the value lies between ± 0.30 and ± […]
What is the 5 era?
What is the 5 era? The book divides the timeline of the universe into five eras: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the […]
Where should the receiver be placed to maximize reception?
Where should the receiver be placed to maximize reception? The receiver of the satellite dish is placed at the focus of the parabola, to maximize signal reception. How many inches should the receiver be located from the vertex for optimal reception? 10.126 inches How do you measure the depth of a parabolic dish? Step 1: […]
Which principle is used in rocket?
Which principle is used in rocket? The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses is explained by the same physical principle—Newton’s third law of motion. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. Another common example is the recoil of a […]
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down?
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down? Another way to say this is that if the acceleration has the same sign as the velocity, the object will be speeding up. And if the acceleration has the opposite sign as the velocity, the object will […]
