The largest planet in the Solar System is Jupiter, which is located five planets from the Sun. It is a gas giant with a mass that is slightly less than one thousandth that of the Sun, but more than two and a half times greater than the combined mass of all the other planets in the Solar System. Observed since ancient times, Jupiter is the third brightest natural object in the night sky of the Earth after the Moon and Venus. It was given the title "Jupiter" in honor of the Roman god and supreme deity.
Helium makes up one-tenth of Jupiter's volume and one-quarter of its mass, despite the planet's primary chemical composition being hydrogen. Though, like the other major planets in the Solar System, it likely contains a rocky core made of heavier elements.

one scientific theory is that at the time of the creation of the universe, that for every matter particle created, an equal amount of antimatter was created. t or f
The scientific theory which says that at the time of creation of universe an equal amount of matter and antimatter was created is still under research. So, it is not possible to say whether the statement is true or false.
In the early universe, there should have been equal amounts of matter and antimatter created by the Big Bang. In any case, today, all that we see from the tiniest life forms on Earth to the biggest heavenly bodies is made up of matter. So, when comparison is drawn there is not that amount of antimatter. The balance must have been shifted by some event. Finding out what happened to the antimatter or why there is an asymmetry between matter and antimatter is one of the most difficult problems in physics.
Despite having opposite properties like electric charge, antimatter particles have the same mass as their matter counterparts. The opposite of the negatively charged electron, for instance, is the positively charged positron. Particles of matter and antimatter are always made in pairs, and if they come in contact with each other, they explode, leaving behind only energy. Particle-antiparticle came into existence just a fraction of seconds after the big bang. It appears that the universe would only contain energy leftover from the creation and destruction of matter and antimatter together.
However, a very small amount of matter, about one particle per billion, was able to survive. Particle physics experiments have demonstrated over the past few decades that the natural laws do not apply equally to matter and antimatter. Physicists are interested in figuring out the reason. Before they decay, researchers have observed millions of spontaneous transformations between particles and their antiparticles.
By studying the subtle differences in the behavior of matter and antimatter particles produced by high-energy proton collisions at the Large Hadron Collider, physicists may be able to determine the nature of this process. Scientists may gain a better understanding of the reasons for the abundance of matter in our universe by studying this imbalance.

a distant observer looks at the surface of a neutron star of 2m and radius of 11 km. how many seconds elapse for this distant observer for every 1 second measured on the surface of the star?
A distant observer looks at the surface of a neutron star of 2m and radius of 11 km. 16.06 seconds are elapse for this distant observer for every 1 second measured on the surface of the star.
The collapsing core of a large supergiant star with a total mass of between 10 and 25 solar masses—possibly even more if the star was very metal-rich—is what we refer to as a neutron star. Neutron star are the tiniest and densest class of stellar objects currently known, with the exception of black holes and some hypothetical objects (such as white holes, quark stars, and weird stars). Neutron stars are roughly 10 kilometers (6 miles) in diameter and weigh 1.4 solar masses. They are the outcome of a large star's supernova explosion coupled with gravitational collapse, which reduces the core's density to that of atomic nuclei from white dwarf star density. Once formed, they gradually cool down and stop actively producing heat, although they can still evolve further through collision or accretion. Neutrons are subatomic particles with no net electrical charge and a slightly larger mass than protons. According to the majority of basic models for these objects, neutron stars are almost entirely composed of neutrons; under the conditions in a neutron star, protons and electrons combine to create neutrons.

if the frequency of ultrasound in increased from 0.77 mhz to 1.54 mhz, what happens to the propagation speed?
If the frequency of ultrasound in increased from 0.77 mhz to 1.54 mhz, the propagation speed is remains same.
Since these are not modifications to the characteristics of the medium, changing the frequency or amplitude of the waves will not alter their speed. In a particular medium, the speed of propagation is constant; only the wavelength varies as the frequency does. Your physical, emotional, and mental bodies feel lighter as your energy or vibration frequency rises. More inner strength, clarity, tranquility, love, and joy are felt by you. Your physical body experiences little or no pain or suffering, and you can manage your emotions with ease.

if c1 = 25µf, c2 = 20µf, c3 = 10µf, and ∆v0 = 21v , determine the energy stored by c2.
The energy stored by c2 is =0.00144478
As per the details share in the above question are as bellow,
The value of the capacitor is ,c1 = 25µf, c2 = 20µf, c3 = 10µf.
While the potential difference is ∆v0 = 21v.
We have to determine the energy stored by c2?
In order to accomplish labor and to produce heat and light, energy must be transmitted to a body or to a physical system. Energy is the quantitative attribute that does this.
When the capacitors are connected in parallel then,
Ceq'= c2+c3= 20+10=30
When the capacitors are connected in series then
Capacitors in series (1/Ceq)=(1/c1)+(1/ceq')= (1/25)+(1/30)
Ceq=13.63μF
Now Energy is equal to one by two into c into v square,
[tex]E=\frac{1}{2} CV^2[/tex]
Substitute the value in above equation we get,
Energy[tex]=\frac{1}{2} (13.63 \times 10^{-6})\times (212)[/tex]
E=0.00144478
