6. The table shows the first five energy levels for mercury. A mercury atom makes a transition that emits a photon with a freque

ncy of 4.91 × 1014 Hz. What was the transition? Use GUESS Method!!
Energy levels of mercury:
n energy level eV
1 -10.38
2 -5.74
3 -5.52
4 -4.95
5 -3.71

Now,
E= 2.03 eV
Also, 
Ef – Ei = E2 – E5 
= -5.74 eV – (–3.71 eV)
= –2.03 eV.
From the conservation of energy, we know that the atom lost energy when that atom emitted the photon. Thus, the transition was from E5 to E2.

The energy levels for an atom are quantized.

Where did we use rotational and irrotational flow​
WARRIOR [948]

Answer:

The term rotational and irrotational flow is associated withe the flow of particles in fluid.

The common example of irrrotational flow can be seen on the carriages of the Ferris wheel (giant wheel).

Explanation:

  • If the fluid is rotating along its axis with the streamline flow of its particles,then this type of flow is rotational flow.
  • Similarly if fluid particles do not rotate along its axis while flowing in a stream line flow then it is considered as the irrotational flow.
  • In majority, if the flow of fluid is viscid then it is rotational.
  • Fluid in a rotating cylinder is an example of rotating flow.

Please please help me, don't guess please my test is timed !!
dimulka [17.4K]

Answer:

a) J = F  t = 40 * .05 = 2 N-s

b)  J = 2 N-s     momentum changed by 2 N-s

c) Initial momentum appears to be zero

J = change in momentum = m v2 - m v1 = m v2 = 2 N-s

v2 = J / m = 2 / .057 = 35 m/s

d) if the impulse time was increased and the average force remained the same then the change in momentum would increase with a corresponding increase in velocity attained - note the increase in v2 in part c)
