The purpose of this question is to motivate the introduction of the â and â' operators for the harmonic oscillator system. we will adapt the simple formula (а — іb)(а + ib) = a2+82 for real numbers a and b. (a) take the harmonic oscillator hamiltonian 1 +mu22 — н 2m 2 and write it in the form hw(q22) q and q is proportional to p, and § is proportional to â. find where in terms of p and â. (b) what is the point of factoring out hw? (c) show that [ë, qi = (d) expand (iq)(e + iq) and simplify. (e) hence show that h can be rewritten as q. and relate â and â* to £ and (f) show that [â, â*] = 1. (g) let {|n)} be the orthonormal energy eigenstates of the harmonic oscillation. recall that the energy eigenvalues are hw (n + 2). use the raising and lowering operator formalism to compute (n| f4 |n).

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
