As an Interstellar Gas Cloud Shrinks

His angular momentum must be conserved so reducing his radius must increase his speed of rotation. As an interstellar gas cloud shrinks in size the law of conservation of angular momentum predicts it will Question 35 options.

Please Help Gas Cloud 1 Is Likely To Form A Star Gas Cloud 2 Is Not Based On This Information Brainly Com

The collapse amplifies the rotation rate.

. The Protoplanet hypothesis suggests that a dense cloud of interstellar gas and dust of at least 10 billion kilometers in diameter was rotating slowly in space about 5 billion years ago. Asked Nov 15 2019 in Physics Space Science by Johana. When the force of heaviness pulling in top top the cloud is better than the stamin of interior pressure pushing out the cloud collapses into a.

According to our theory of solar system formation which law best explains why the central regions of the solar nebula got hotter as the nebula shrank in size. Because the gravitational force pulls the gas particles together the cloud shrinks and under the right conditions a star may be formed. The other part of the gravitational potential energy is released through.

However along the. The collapse provides enough kinetic energy to the particles for hydrogen fusion to occur. As an interstellar gas cloud shrinks in size its gravitational potential energy.

As an interstellar gas cloud shrinks in size the law of conservation of angular momentum predicts it will. When a spinning ice skater pulls in his arms he spins faster because __________. Gas can easily collapse along the rotation axis or perpendicular to the plane of rotation.

But in a rotating cloud the gas does not collapse equally in all directions. A cloud of interstellar gas is rotating. This means that if an object shrinks its rotation rate must increase to compensate.

Stars type in cold dense regions of space called molecule clouds. B decreases because its angular momentum is conserved. The ISM is the name given to the gas and dust that exists between the stars within a galaxy.

As an interstellar gas cloud shrinks in size its gravitational potential energy gradually transforms into other forms of energy. Due to the collisions between particles the cloud will heat up. This photograph shows the Orion Nebula an interstellar cloud in which.

The gravitational collapse of an interstellar. The Interstellar Medium. A Heat up B Spin slower C Cool off D Continue shrinking.

As an interstellar gas cloud shrinks in size its gravitational potential energy. 15 As an interstellar cloud of hydrogen gas shrinks in size its rate of rotation A increases because its angular momentum is conserved. C decreases because the force of gravity strengthens as the cloud shrinks.

According to the virial theorem the gravitational potential energy of the the gas cloud is converted into two forms of energy. An interstellar cloud is generally an accumulation of gas plasma and dust in our and other galaxies. Molecular clouds are perfect star-forming regions because the combination of these atoms into molecules is much more likely in very dense regions.

What happens when an interstellar cloud fragment shrinks Summary. As an interstellar gas cloud shrinks in size the law of conservation of angular momentum predicts it will. If an interstellar gas cloud shrinks in size what does the law of conservation of energy predict it will do.

Put differently an interstellar cloud is a denser-than-average region of the interstellar medium ISM the matter and radiation that exists in the space between the star systems in a galaxy. As time passed the cloud shrank under the pull of its own gravitation or was made to collapse by the shockwave due to explosion of a passing star Supernova. Would the angular velocity of the star be less than greater than or equal to.

It is 99 gas and 1 dust by mass. As an interstellar gas cloud shrinks in size its gravitational potential energy gradually transforms into other forms of energy.
