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.

Of the following reactions, which is a fusion reaction?
a.
uranium-235 absorbing a neutron and splitting into xenon-140, strontium-94, and two neutrons
b.
hydrochloric acid combining with sodium hydroxide to form a salt and water
c.
carbon-14 decaying into nitrogen-14 and a beta particle
d.
curium-246 combining with carbon-12 to form nobelium-254 and four neutrons
Answer:
Option D is correct.
Explanation:
It is fusion reaction.because curium combines with carbon to form a big nuclei of nobelium.[tex]Cm_{246} +C_{12}[/tex] → [tex]No_{254}[/tex]
Hence, it is the fusion reaction.
What is fusion?When two or more nuclei fuse together to form a heavy nucleus with the energy released, is called fusion.

If 10 crests and 10 troughs pass through a point in 5 seconds. Calculate its time period and frequency?
Answer:
frequency = 5 /s
period = 0.5 s/
Explanation:
number of revolution = 10+10/2 = 20/2 = 10
frequency = n/t = 10/5 = 5 /s
period = t/n = 5/10 = 0.5s

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.
