We discussed the properties of operators used in quantum mechanics. let us prove some of the identities mentioned there. 1. show that any linear operator î can be represented as l = a + ib. where a and b are hermitian operators (hint: write a and b in terms of l). (2 pt) 2. consider the commutators (a, bc and ab, ĉof any three linear operators a, b, and ĉ. show that they can be expressed via the commutators (a, b], (a, c), and (b, c). (3 pt) 3. consider the following operator, (a-ib)-1. assuming that is small, expand this operator in a power series in 1. hint: write (a - xb)-1 = "în and determine cn. remember that a and b do not necessar- ily commute

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
