What else can I help you with?
If we compare the force of gravity to strong nuclear force we could conclude that?
the strong nuclear force is much stronger than the force of gravity. Gravity is the weakest of the four fundamental forces, while the strong nuclear force holds atomic nuclei together and is much stronger than gravity on the atomic scale.
What object is so dense and has such strong gravity that no light can escape it?
A black hole is an object with such strong gravity that not even light can escape its pull. This intense gravity is due to its extreme density, formed when a massive star collapses in on itself.
What is stronger than earths gravity?
The gravity of a black hole is stronger than Earth's gravity. Black holes have such a strong gravitational pull that not even light can escape from them.
How are gravity and strong nuclear force different?
Gravity is a universal force that acts between all objects with mass, while the strong nuclear force is a short-range force that holds atomic nuclei together. Gravity is much weaker than the strong nuclear force and acts over long distances, while the strong force is responsible for binding protons and neutrons together in atomic nuclei.
How is the strong force different from gravity and electromagnetism?
The strong force acts at very short distances within the atomic nucleus, binding protons and neutrons together. It is much stronger than both gravity and electromagnetism at these distances. Gravity is a force of attraction between masses, acting at macroscopic scales, while electromagnetism governs the interactions between charged particles.
Which probe saw a comet's nucleus?
The European Space Agency's Rosetta spacecraft was the probe that closely studied a comet's nucleus. It visited Comet 67P/Churyumov–Gerasimenko in 2014 and deployed a lander, Philae, to study the comet's surface.
When will the Rosetta space probe land?
The current scheduled contact with comet 67P/G-C is 12 November 2014
What comet occurs the most?
encke's comet that appears every 3.3 years
What is Philae?
Philae is an ESA (European Space Agency) lander vehicle. It successfully landed on comet 67P on November 12, 2014.
What is the name of the comet that Rosetta is currently following?
The comet that the Rosetta spacecraft is following is called 67P/Churyumov-Gerasimenko. Rosetta was launched by the European Space Agency in 2004 and successfully entered orbit around the comet in 2014, providing valuable data about its composition and behavior.
What is happening to comet 67p as it approaches the sun?
As comet 67P approaches the Sun, it experiences increased solar radiation and heat, which causes its ices to sublimate into gas, creating a glowing coma and a tail that extends away from the Sun. This process also leads to the release of dust and other materials from its surface, contributing to its unique shape and activity. The interaction between the comet's outgassing and the solar wind can create spectacular features, making it a fascinating object of study for astronomers.
What names have been given to different comets?
Some famous comets and their names include Halley's Comet, Comet Hale-Bopp, Comet Shoemaker-Levy 9, and Comet 67P/Churyumov-Gerasimenko. Each comet is named based on the astronomers who discovered them or based on a specific naming convention.
Is the ion tail of a comet on the top or bottom?
It is on the side of the comet furthermost from the Sun. Conventional wisdom dictates gravity defines up and down therefore it is on "top" of the comet since the comet is trapped by the gravity of the Sun.
What is the gravity of Comet Hale Bopp?
7
How many comets have been studied by spacecraft?
As of 2021, spacecraft have studied five comets up close: Halley's Comet (by the European Space Agency's Giotto spacecraft), Comet Borrelly (by NASA's Deep Space 1), Comet Wild 2 (by NASA's Stardust spacecraft), Comet Tempel 1 (by NASA's Deep Impact spacecraft), and Comet 67P/Churyumov-Gerasimenko (by the European Space Agency's Rosetta spacecraft).
What makes comet to fall on earth?
earth's gravity
When have comets been spotted over the last hundred years?
Over the last hundred years, notable comets include Halley's Comet, which was last visible in 1986, and Comet Hale-Bopp, which captivated observers in 1997. Comet NEOWISE made a spectacular appearance in July 2020, and Comet Leonard was visible in December 2021. Additionally, Comet 67P/Churyumov-Gerasimenko was extensively studied by the Rosetta mission, which provided significant insights into comets from 2014 to 2016.
