Two small plastic spheres are given positive electrical charges. When they are a distance of 15.6{\rm cm} apart, the repulsive force between them has a magnitude of 0.235{\rm N} .What is the charge on each sphere if the two charges are equal? What is the charge on first sphere if it has four times the charge of the other?

Determine the probability mass function-pmf : encounter a sequence of birds while walking in the park. The birds can either be blue (B) or red (R). We let X be the random variable corresponding to the number of birds we encounter until seeing the first blue one.

Define when trans-1-chloro-2-ethylcyclohexane reacts : Draw the major E2 reaction product formed when trans-1-chloro-2-ethylcyclohexane reacts with hydroxide ion in DMSO

State three orbital designations that would be incorrect : Write three orbital designations that would be incorrect and explain why each is incorrect. For example, 1p would be an incorrect orbital designation because there is no p sub-shell in the first orbit.

Explain unpaired electrons are attracted by magnetic fields : One bit of evidence that the present theory of atomic structure is "correct" lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit paramagnetism.

Find equivalent impedance of transformer of low-voltage : A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
