Power supplies used in desktop computers many years ago, commonly referred to as AT, had a power switch that switched on the 120
Karolina [17]

Answer:

Power supply relay coil

Explanation:

The power supply known as ATX used in today's PCs is very complicated kind of power supply. The main objective of ATX form of the power supply is conversion of the input supply from the line into different voltages to be supplied in order to run the desktop computer's mother board.

While the AT supply that was used many years back that supplied about 120 VAC, The ATX power supply in today's world is capable of supplying power supply of about 300 W or more.

Power supply relay coil is a solitary estimation of source voltage planned by configuration to be connected to the input or coil.

An excited electron in an Na atom emits radiation at a wavelength 589 nm and returns to the ground state. If the mean time for t
11Alexandr11 [23.1K]

Answer:   Inherent width in the emission line: 9.20 × 10⁻¹⁵ m or 9.20 fm

                length of the photon emitted: 6.0 m

Explanation:

The emitted wavelength is 589 nm and the transition time is ∆t = 20 ns.

Recall the Heisenberg's uncertainty principle:-

                                 ∆t∆E ≈ h ( Planck's Constant)

The transition time ∆t corresponds to the energy that is ∆E

E=h/t = \frac{(1/2\pi)*6.626*10x^{-34} J.s}{20*10x^{-9} } = 5.273*10x^{-27} J =  3.29* 10^{-8} eV.

The corresponding uncertainty in the emitted frequency ∆v is:

∆v= ∆E/h = (5.273*10^-27 J)/(6.626*10^ J.s)=  7.958 × 10^6 s^-1

To find the corresponding spread in wavelength and hence the line width ∆λ, we can differentiate

                                                    λ = c/v

                                                    dλ/dv = -c/v² = -λ²/c

Therefore,

      ∆λ = (λ²/c)*(∆v) = {(589*10⁻⁹ m)²/(3.0*10⁸ m/s)} * (7.958*10⁶ s⁻¹)

                                 =  9.20 × 10⁻¹⁵ m or 9.20 fm

     The length of the photon (<em>l)</em> is

l = (light velocity) × (emission duration)

  = (3.0 × 10⁸  m/s)(20 × 10⁻⁹ s) = 6.0 m

grigory [225]

There are different kinds of care given to machine parts. Technician A says that a pilot bearing should always be replaced when a clutch is replaced is a true statement and thus is the only correct one.

<h3>When should I replace my pilot bearing?</h3>
  • If one notice vibration on the clutch pedal, it is shows that it is worn-out bearing and thus needs changing.

Most times, pilot bearing is often replaced as kind of precautionary measure that is taken when clutch is replaced.

Torsional vibrations are said to be vibrations due to firing force twisting and accelerating of the crankshafts when a cylinder fires and cannot be absorbed by oft-dampened clutches.
