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.

What is the difference between a pure
substance, solution, and mixture?
A pure substance cannot physically be separated, and is made out of one atom (or molecule). Unlike a mixture, however, which are made out of two or more atoms or molecules. A solution in itself is the example of a mixture. (The composition of a pure substance being fixed, and a mixture's being varying depending on which.) And a solution branching off from a mixture into being either homogeneous mixtures or heterogeneous mixtures.

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
hope this helps
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.

What is the process of satellite orbiting?The goal of satellites is to achieve balance. They rotate around the globe quickly enough to avoid being entirely drawn down into the planet's center of gravity, yet slowly enough to avoid drifting out into space.
When a satellite is travelling at the right speed, the earth's gravitational attraction is just strong enough to keep it in place. A satellite must move quicker to maintain orbit the nearer it is to the earth's surface. Additionally, satellites' orbits are circular or elliptical due to the continual pull of the curved surface of the planet.
Therefore, gravity plays a crucial role in our daily lives, whether it's keeping us anchored to the planet's surface or keeping the satellites we use to communicate and learn more about our environment in orbit.
