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 […]
What is heat loss by radiation?
What is heat loss by radiation? Radiation is a form of heat loss through infrared rays. This involves the transfer of heat from one object to another, with no physical contact involved. For example, the sun transfers heat to the earth through radiation. The last process of heat loss is evaporation. How can a patient […]
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 […]
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 […]
What are two signs of hydroplaning?
What are two signs of hydroplaning? It’s sometimes hard to tell when you’re hydroplaning. The vehicle’s rear end may be a little squirrelly. Steering may feel loose or too easy. Watch for standing water or spray from vehicles in front of you. Should I buy AWD or FWD? It’s lighter, so front-wheel drive cars tend […]
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 […]

What is the relationship between angular speed frequency and period?
What is the relationship between angular speed frequency and period? Period, , is defined as the amount of time it takes to go around once – the time to cover an angle of radians. Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, […]
What are the disadvantages of using a pinhole camera?
What are the disadvantages of using a pinhole camera? The image formed does not give any details. Usually, it is faint. Image is obtained on the screen and no permanent record of the image can be obtained. Pinhole camera cannot be used for studying moving objects. What are the major differences between a pinhole camera […]
What would happen if the orbit was circular?
What would happen if the orbit was circular? “If the Earth’s orbit were a perfect circle, we would not have seasons.” This statement is clearly false. A perfectly circular orbit would mean that the earth is always the same distance from the sun. However, the primary cause of our seasons is the tilt of the […]
