Suppose the Sun were suddenly to shrink in size but that its mass remained the same. According to the law of conservation of angular momentum, what would happen?

The Sun would rotate faster than it does now. More test answers on https://studyhippo.com/chapter-4-39279/

Based on the law of conservation of angular momentum, what would happen to a collapsing cloud of gas and dust–isolated in space with no external forces–as its size decreases? Choose one: A. The cloud will lose mass. B. The cloud will spin faster. C. The cloud will spin more slowly. D. The cloud will gain mass. E. The cloud will not be able to collapse at all.

The law of conservation of angular momentum

According to our theory of solar system formation, which law best explains why the solar nebula spun faster as it shrank in size? – The law of conservation of angular momentum – Einstein’s law E=mc2 – The law of universal gravitation – The law of conservation of energy More test answers on https://studyhippo.com/astro-ch-6-2-39668/

Law of conservation of angular momentum

An individual object can change its angular momentum only by transferring some angular momentum to or from another object–> Total angular momentum can never change Angular Momentum= Mass x Velocity x Radius More test answers on https://studyhippo.com/ast-101-exam-2-laws-of-astrophysics/

6) According to our theory of solar system formation, why do all the planets orbit the Sun in the same direction and in nearly the same plane? A) The original solar nebula happened to be disk-shaped by chance. B) Any planets that once orbited in the opposite direction or a different plane were ejected from the solar system. C) The laws of conservation of energy and conservation of angular momentum ensure that any rotating, collapsing cloud will end up as a spinning disk. D) The Sun formed first, and as it grew in size it spread into a disk, rather like the way a ball of dough can be flattened into a pizza by spinning it. E) Luck explains it, as we would expect that most other solar systems would not have all their planets orbiting in such a pattern.
