What is the potential energy of a dipole in uniform electric field? P.E=−pEcosθ=−p⋅E. This is negative when θ is acute and positive when θ is obtuse. In which situation the potential energy of dipole is maximum and minimum? Potential energy is maximum when dipole moment is anti parallel the the direction of EF ( condition […]

Can a matrix have nullity 0? As to why a matrix is invertible if is has zero nullity, this comes back to what it means for a matrix (or more specifically a linear map) to be invertible. It means that you can reverse its effects. If a matrix has nullity above 0, that means there […]

What is a real life example of friction? Following are the ten examples of friction in daily life: Walking –We can walk only if we apply frictional force. Friction is what holds your shoe to the ground. The friction present on the ice is very little, this is the reason why it is hard to […]

What is resistance and current? Resistance is a measure of the opposition to current flow in an electrical circuit. All materials resist current flow to some degree. They fall into one of two broad categories: Conductors: Materials that offer very little resistance where electrons can move easily. What are the types of resistance? Resistor types […]

How jewelers cut and polish diamonds so they sparkle? As light hits a diamond, it penetrates the diamond, bounces around and reflects within the diamond and ultimately returns light to your eye. That is the sparkle that you see. The cutting of a diamond directly impacts the amount of light performance achieved. How do you […]

What are the 4 factors that can affect a car going into a curve? The four factors that can affect control over a curve include speed, sharpness of the curve, load (being what the vehicle is carrying, how much weight), and shape of the road. What is the most important factor in maintaining control of […]

Can you swim under an island? No, the land doesn’t go all the way down under an island. Rock and sand floats. You can swim right underneath islands. What is the smallest island in the world? Bishop Rock What is the most crowded island on earth? Its significant population, compared with its small size, results […]

Do lone pairs affect bond length? Re: Lone Pairs Affect on Bond Strength Lone Pairs of electrons on neighboring atoms weaken the bond because of electron repulsion. Neighboring atoms in a molecule that have lone pair electrons will not be held together in their bond as tightly because the lone pair electrons of both atoms […]
