1. a=(v-v0)/t
a=14 m/s / 2s
a=7 m/s^2
2. a=(v-v0)/t
a=(30 m/s - 0 m/s) / 12 s
a=2.5 m/s^2
3. a=(v-v0)/t
a=(37 m/s - 22 m/s) / 2 s
a= 7.5 m/s^2
4. a=(v-v0)/t
a=(12 km/s - 0 km/s)/8 s
a=1.5 km/s^2
etc

Consider a resonator with ω0 = 100 rad/sec and a Q factor of 100. Calculate the time takes it to settle within 2% of the final v

Alla [95]

Answer:

8 s

Explanation:

Damping factor, F is given by

$F=\frac {1}{2Q}$ where Q is quality factor

Also, we know that the settling time, T is given by

$T=\frac {4}{FW}$ where W is the resonant frequency.and substituting the first equation here we get

$T= \frac {4\times 2Q}{W}$

Since it takes 2% of final value to settle and considering 100 rad/s for resonant frequency and taking quality factor of 100 then

$T=\frac {4\times 2\times 100}{100}= 8 s$

does a Neon atom emits specific frequencies of light that correspond to decreases in energy of its electrons.

zlopas [31]

Answer:

Yes, the frequency of light emitted is a property of the difference between the levels of energy of its electrons.

Explanation:

Neon atom is a noble gas which glows when its electrons de-excites after absorbing energy.

Niels Bohr postulated that the energy level in all atoms are quantized, thus electrons do not exist in-between two levels. When electrons in the Neon atom are excited, this increase in energy causes them to jump to a higher energy levels. On de-excitation, the electrons drops to their initial level releasing the absorbed energy in the form of a photon.

The photon emitted has a frequency that is directly proportional to the energy change in the electron.
