Which three rocky planets have atmospheres
Which waves have oscillations parallel to their direction of motion
Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.
Explanation:
The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.
What are sound waves?A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.
Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

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.
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.

The density of iron is 7.97 g/cm. Express it in Sl unit.
Answer:
[tex]d=7970\ kg/m^3[/tex]
Explanation:
Given that,
The density of iron is 7.97 g/cm³.
We need to find the density in SI unit. The SI unit of density is kg/m³.
We know that,
1 kg = 1000 g
1 m = 100 cm
So,
[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]
So, the density of the iron is [tex]7970\ kg/m^3[/tex].

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.

The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical
rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.
Answer: Boat P
Explanation:
Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436
The minimum time taken to unwind the rubberband is by boat P.
The highest amount of force to unwind the rubberband is generated by boat P.
Force, Mass and AccelerationThe table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.
Force = Mass [tex]\times[/tex] Acceleration
For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]
For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]
For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]
For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]
Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10 2 T acting at
right angles to the wire of length 19 m and current of 0.043 A? Round your answer to 2 significant
figures.
Answer:
2900 N
Explanation:
We are given;
Magnetic flux density; B = 3.6 × 10² T
Length of wire; L = 19 m
Current; I = 0.043 A
Formula for force in this regards is;
F = BIL
Where;
B is Magnetic flux density
I is current
L is length
Thus;
F = 3.6 × 10² × 0.043 × 19
F = 2941.2
To 2 significant figures gives;
F = 2900 N

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
