Sound is produced when a matter vibrates. Sounds consists waves and these waves travel as a longitudinal waves. Sound travels fastest in solids because the particles are closer. The speed of sound depends on the temperature of matter. The higher the temperature, the higher the speed of sound is. The properties of sound are reflection and refraction. In reflection, the sound wave turns back when it hits a barrier. A good example of this are echoes and reverberations. On the other hand, refraction is the bending of sound waves.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

12. Analysis of Results
1.What is Earth made of?
2.Describe the different layers of Earth’s
interior.

Which Parts of Earth Are Hit By
Earthquakes: sand and polysterene
Think This Over:
How does an earthquake occur?
16. Earthquake is the sudden
shaking of the ground that
we feel when rock layers of
Earth suddenly slip past one
another to a new position.
17. • Earthquakes results from the
release of stored energy
within earth’s interior.
• Earthquake cannot be
predicted.
18. • The fracture in he
surface of the crust
where two blocks of
rocks slip is called the
fault.
19. Map Reading/ Analysis
1. What do you notice with the edge
landforms among the continents?
2. Do the continents show any
evidence that they were connected
before as one big land mass? What is
this evidence?
