The collision of the deep impact probe with the nucleus of comet tempel 1 in 2005 revealed the nucleus as a rubble pile held tog
balu736 [363]

Answer

correct Answer is gravitation

Explanation

In 2005, collision of deep impact probe with the nucleus of comet tempel 1 was carried out. In this probe the length of Tempel 1's nucleus was about 5km long. In this probe it was revealed that the nucleus behave as a rubble pile which is held together by gravitation.

In this probe speed of Tempel 1  which is moving towards the nucleus was 10km/s.  In this probe series of images was recorded and cloud of debris was analyzed,It was discovered that comet is made up of a primordial chunk of solar system material. It was observed that Tempel 1's has tiny grains of silicates, iron compounds, complex hydrocarbons, and clay and carbonates thought to require liquid water to form it was more appropriate for a cosmic souffle, as the nucleus is apparently porous and fluffy.

<h2>Activities illustrates the Nature of a Dialectical Process</h2>

Dialectical method is at center a conversation among two or more characters carrying diverse localities of opinion regarding a topic but hoping to build the fact by reasoned disputes. Dialectic relates a discussion but cleft of biased components such as passionate plea and the recent derogatory knowledge of eloquence.

It can be compared with the dialectic method where one faction of the communication informs the another. Logic is alternatively identified as lesser reasoning, as objected to superior thought or commentary.

A leaf fell from a tree branch. The path it followed is shown in the diagram below.
prisoha [69]

The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.

<h3>What is an air current?</h3>

An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.

When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.

The maximum amount of work that can be extracted is equal to the changein Gibbs free energy___________.
steposvetlana [31]

Answer:

The statement is true

Explanation:

The Gibbs free energy is defined as:

ΔG = ΔH - TΔS

     Where  ΔH : Change in the  enthalpy

                   T : The temperature

                  ΔS : Change in the entropy

And the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure.

If the thermodynamic process is isothermal and isobaric, then the statement is true.
