What happens to the molecules when the solid changes phase?
they begin to move quickly and can break away from other molecules
Answer:
When solid changes atoms/molecules begin to speed up and move around. Compared to when they are in the solid phase, where they barely move and are slow and are compacted.

6. Dentists use a soft, clay-like material to make a filling for a cavity. The filling stays soft under the
light of the dentist's lamp, but it hardens when the dentist shines an ultraviolet flashlight on it. Why
does light from the ultraviolet flashlight harden the filling when light from the lamp does not?
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.
What is ultravoilet ray?Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.
Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,
Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.

Two ways I can decrease the force attraction between two charged objects?
Answer: Change distance and charge
Explanation:
Increase the distance between the two particles, and remove charge from one or more of the particles.
Coulomb's Law is:
[tex]F=\frac{kq_1q_2}{r^2 }[/tex]
k being a constant of 8.99 x 10^9 (units)
q1 and q2 being the magnitude of charges
r being the distance between them
All music, _______ in the world, is from only ______ notes.
Answer:
All music in the world, is form only two notes and those notes are described below in detailed explanation.
Explanation:
In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.
Varieties Of Musical Notes You Require To Understand
Semibreve (Whole Note)
Minim (Half Note)
Crotchet (Quarter Note)
All music, listened to in the world, is from only twelve (12) notes.
A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.
A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.
Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.
This ultimately implies that, any musical piece that you may have come across in this world comprises only twelve (12) notes and these include:

Wave 1
a) How many waves are there in this wave train?
b) Wavelength cm c) Amplitude
cm
Answer:
see below
Explanation:
a wave means one complete wave which is 1 period
so a) 5 complete waves
wavelength is the shortest distance between any two points in phase
so wavelength = 1 CM
amplitude of a wave is the maximum displacement of a particle from its rest position
so amplitude = 3 CM
