What are some things that have been engineered to help people deal with the effects of gravity?

Answer:

equivalence principle. Particles follow geodesics that are extremal paths in spacetime. These paths are the same for any mass m so long as this test mass is small m << M for M the mass of a central mass that defines a gravity field. If the spacetime curvature is due to a gravity wave or some other physics, the curvature of this field R is such that R >> 8πGm^2. If this test mass is sufficiently large it has its own appreciable curvature and this results in a highly complex problem similar to the 3-body problem in Newtonian mechanics.

I have though been thinking about this a bit differently. The equivalence principle states that the freely falling frame is equivalent to a frame in flat spacetime far removed from any gravity field. I have been thinking of this according to quantum field theory. A freely falling frame is one which has a vacuum equivalent to a quantum vacuum in flat spacetime. The geodesic the frame falls under is one which preserves this vacuum.

This may be extended to massive particles and massless particles. A massless particle is on a null geodesic and is then on a “null frame.” These frames are then projective varieties over massless quantum fields in that vacuum. These massless fields all have transverse modes, but no longitudinal modes. A massive particle has a longitudinal mode, and the vacuum modes have dispersion as a result. This is due to the presence of the Higgs field.

An accelerated frame is one which has a vacuum equivalent to a particular vacuum near a black hole. Depending on the acceleration parameter this can be a different vacuum. In this way aspects of spacetime physics can be thought according to quantum mechanical or quantum field properties. Spacetime is probably an emergent phenomenon of quantum physics.

Experts and non-expert groups do not categorize using the same levels. Suppose we compare horticulturalists to people with littl
lubasha [3.4K]

Answer:

- Subordinate; basic.

Explanation:

As per the question, given that five different plants are there to be labelled; it could be predicted that the expert group would firstly label the plants on 'subordinate' level while the 'non-expert' group would label on the 'basic' level. <u>The key reason for this difference is that the experts possess essential knowledge of the domain while the non-experts would move gradually towards the expertise</u>. Thus, the former views the information in a distinctly organized and meaningful pattern significant to the aspects of their knowledge while the latter lacks in such aspects and views the given domain or situation differently.

Whats the difference between high-use academic words and key terms ?
Helen [10]
fall into three tiers.
Tier 1 words include basic or high-frequency vocabulary words and usually don’t include multiple meaning words.
Tier 2 words are less familiar to students but help in comprehending written texts and conversations shared between the teacher and student. Tier 2 words are “general academic words” and sometimes may be referred to as “rich vocabulary.” These words are precise but more subtle forms of familiar words and include multiple meaning words. For example, instead of saying “he walked,” one may say “he sauntered.” Tier 2 words cross over into a variety of domains or subject areas.

2) What were the central Ideas of protestant Reformers, and why were they appealing to various groups across Europe?
valina [46]

Answer :

The central idea focused on emphasizing on faith, the power of god's grace and centralizing the Bible.

Explanation:

Martin Luther and John Calvin were the greatest protestant reformers. : John Calvin and Martin Luther broke from the Catholic Church by seeing the corruption in it. Luther believed that the individual has control over what happens in his life. Calvin believes in the doctrine of predestination.

Most Protestant reformers appeal to various groups across Europe because peasants and artisans were the victims of violent social and economic dislocation. The growing population led many to move from rural to towns. With declining wages, increasing taxation, rising prices caused a wide gap between the poor and the rich. Poverty, resentment and social discontent if the mass were some of the reason for their success.

Protestant ideas welcome to educated people and urban residents because if the printing press. Rulers also attracted because it brought a religious change in their kingdoms which allowed rulers to split from the Catholic Church and hold its supreme power in the state.
