docker41 [41]

Answer:

Angular velocity is same as frequency of oscillation in this case.

ω = \sqrt{\frac{7K}{m} } x [\frac{L^{2}}{mK}]^{3/14}

Explanation:

- write the equation F(r) = -Kr^{4} with angular momentum <em>L</em>

- Get the necessary centripetal acceleration with radius r₀ and make r₀ the subject.

- Write the energy of the orbit in relative to r = 0, and solve for "E".

- Find the second derivative of effective potential to calculate the frequency of small radial oscillations. This is the effective spring constant.

- Solve for effective potential

- ω = \sqrt{\frac{7K}{m} } x [\frac{L^{2}}{mK}]^{3/14}

What has research determined about the orbit of an electron around a nucleus?
Wittaler [7]
<span>I think the correct answer from the choices listed above is the second option. The research that determined about the orbit of an electron around a nucleus would be that electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model.</span>

Because of its retrograde spin, Venus has a longer solar day than its year : Select one:
ELEN [110]

Answer:

FALSE

Explanation:

The rotation of a planet is determined by the rotation of the initial mass that formed the planet.

The retrograde spin has nothing to do with the length of the solar day.

One reason why the rotation of Venus is slow may be due to the tidal lock and the sun's gravity. One solar day in Venus lasts 243 Earth days and it orbits the sun every 224.7 Earth days.
