Chapter 32, Problem 2RQ
What plutoid was downgraded from planetary status in 2006?
Expert Solution & Answer
To determine
The reason for downgrading from planetary status of Plutoid in 2006.
Answer to Problem 2RQ
The plutoid was downgraded from planetary position in 2006 because the material inside the plutoid not settled as the core of the plutoid.
Explanation of Solution
The large size icy objects originate from the Kuiper belt are called Plutoid. The size of these objects is same as of Pluto.
The large size objects in space are called planets if all the material is collected in the orbital paths. The all the material in the Kuiper belt is not settled in the form of the core of the planet. The dense material of planets settled in the core.
The dense material of the plutoid is not settled in the form of core, so it does not include in the category of the planet.
Conclusion:
Therefore, the plutoid was downgraded from planetary position in 2006 because the material inside the plutoid not settled as the core of the plutoid.

- Three slits, each separated from its neighbor by d = 0.06 mm, are illuminated by a coherent light source of wavelength 550 nm. The slits are extremely narrow. A screen is located L = 2.5 m from the slits. The intensity on the centerline is 0.05 W. Consider a location on the screen x = 1.72 cm from the centerline. a) Draw the phasors, according to the phasor model for the addition of harmonic waves, appropriate for this location. b) From the phasor diagram, calculate the intensity of light at this location.arrow_forwardA Jamin interferometer is a device for measuring or for comparing the indices of refraction of gases. A beam of monochromatic light is split into two parts, each of which is directed along the axis of a separate cylindrical tube before being recombined into a single beam that is viewed through a telescope. Suppose we are given the following, • Length of each tube is L = 0.4 m. • λ= 598 nm. Both tubes are initially evacuated, and constructive interference is observed in the center of the field of view. As air is slowly let into one of the tubes, the central field of view changes dark and back to bright a total of 198 times. (a) What is the index of refraction for air?
