What famous person has dissociative identity disorder? The painter Kim Noble is a niblet-sized woman with long, auburn hair and startlingly blue eyes. She lives in a small terrace house in south London with her 14-year-old daughter Aimee, two dogs and more than 100 separate personalities. Kim, 50, has dissociative identity disorder (DID). Does a […]

Why are hybrid orbitals formed? Hybrid orbitals are the result of a model which combines atomic orbitals on a single atom in ways that lead to a new set of orbitals that have geometries appropariate to form bonds in the directions predicted by the VSEPR model. The VSEPR model predicts geometries that are very close […]

What does an emission spectrum look like? An emissions spectrum looks like a set of colored lines on a black background as opposed to an absorption spectrum which looks like black lines on a colored background. It’s a set of frequencies of the electromagnetic spectrum emitted by excited elements of an atom. Which property can […]

Which QB can throw the fastest? Mahomes How fast do pro football players throw? The average speed at the NFL combine is 54 mph. Tom Brady was clocked at 61 mph recently. Josh Allen was clocked at 62 mph. Who has a stronger arm Josh Allen or Patrick Mahomes? As for throwing speed, Mahomes threw […]

What are the major differences between the inner and outer planets? The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of […]

Are mass number and atomic number the same? Atomic Number and Mass Number While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is […]

Is the major concern in frequency reuse? Co-channel interference is a major concern. The frequency reuse distance, D, (i.e., the distance between the two adjacent co-channel cells of radius R) is related to the number of cells in a frequency reuse pattern K by the following CCI reduction factor: [D/R]2=3K. K-1: frequency reuse efficiency. Why […]

What does an eraser symbolize? Moreover, an eraser can stand for so much more than just a means of correction. It represents a means of redemption. The eraser serves as a reminder that mistakes are bearable and, in the end, there is a solution to even the most difficult of problems. Why does an eraser […]

What is the electric field due to a dipole? The direction of the electric field at points on the dipole axis is directed along the direction of dipole moment vector but at points on the equatorial plane it is directed opposite to the dipole moment vector, that is along – . (ii) At very large […]

How many electrons are transferred in ionic bonds? The tendency to form species that have eight electrons in the valence shell is called the octet rule. The attraction of oppositely charged ions caused by electron transfer is called an ionic bond. The strength of ionic bonding depends on the magnitude of the charges and the […]
