Assignment al Affiliation Assignment 3: Astronomy Essay Below is a formula used to work out velo of a galaxy; Vr = CZ C whichis considered to be the speed of the light is 300,000 Km/s and Z is the redshift respectively.
In order to find the Redshift, the fraction of the two wavelength ratios must be considered.
This is shown in the below calculations.
Z = (Wavelength- Rest Wavelength)/ Rest Wavelength)
Therefore the Velocity is,
300,000 X (Wavelength- Rest Wavelength)/Rest Wavelength)
a) Galaxy I has a Wavelength of 8204 and the Rest Wavelength of 6563. Therefore, calculation the Radial velocity will be;
300,000 Km/s (8204-6563)/6563
= 75011.4277 Km/s
b) Galaxy II has a wavelength of 6549 and the Rest Wavelength of 6563. Therefore, calculation of radial velocity will be as follows;
300,000 Km/s (6549-6563)/6563
= -639.95124 Km/s
2. In respect to particle interaction, the following reactions must take place;
Conservation of energy takes place in the process of the interactions thus involving momentum aspect. Besides, conservation of charge takes place together with the Lepton and the Baryon number. A strong interaction between the weak particles occurs hence making the process of annihilation take place that involves a proton and an antiproton. In order for one anti up and up quarke to take place, annihilating which is responsible for producing energy is examined.
3. Proofs about the dark energy which are related with the galaxy clusters have been developed and they have distance difference that shows the densities of the galaxy which has a year difference with the universe. The proofs were presented through the view of the South Pole Telescope where by the brightest cluster galaxies have been found. They are undergoing a violent internal motion caused by a smashup from other galaxies. Abell 3627 generates an x ray which is blue along with hydrogen light. On the other side, Eso 137-001 galaxy has been seen for 260000 light years. It has a tail which the scientists have failed to understand to date. Clusters of galaxies are a collection of galaxies which are bonded by the gravity that is bounded by hot gases. The tails which were formed from the hot gas formed by the spiral arms of the galaxies. This causes an effect to the galaxy hence evolution changes the formation of the stars.
4. In relevance to the top down structure formation, the scenario first forms the large pancakes then followed by the fragment that forms the lumps which are sized. The scenario is important because of the information concerning the existence of the large sheets with low density. In respect to bottom up structure’s scenario, there occurs a formation of the galaxies which are small and dwarfs first, followed by the formation of the clusters.
5. The world was molten many years ago. It took some years for the earth to cool and pass through the process of conduction and radiation. In respect to laws of thermodynamics, the earth has around 24 to 40 million years. The amount of the salt in the oceans also shows that it must have taken them time for salt evaporation process to occur. Nowadays, oceans have only a small amount of salt. The thickness of existing sedimentary rocks is over three million years old. Marine mollusks have also a number of series of million years on the universe thus the world is old enough to have been completed many years. The decay of the radioactivity processes also passes a number of age measures of the rocks and minerals on earth.

...Evaluate how far the provisions of the Landlord and Tenants (Covenants) Act 1995 can be said to benefit tenants to the detriment of landlords? The property disputes are quite common now a days and lack of proper legal provisions may complicate these problems further (Rotherham, 2000). Landlord and tenant problem is one of the common property disputes witnessed by us through out the world (Canadian Legal Information Institute, 1973).

### Assign2

...Question Question 2 Harlow Shapley and Haber Curtis are two well-known astronomers who debated on the structure and form of the universe, in relation to our galaxy. They based their argument on the study of a galaxy known as the Milky Way. The latter argument known as the great debate brought out a number of issues about the universe, which Shapley and Curtis held different ideas or assumptions on their relation to our galaxy. Hence, Curtis and Shapley disagreed on issues such as the diameter of our galaxy, the distance of the sun in relation to our galaxy, and finally the description of the spiral nebulae in the sky. Curtis held his argument that our galaxy bares a diameter of 30,000 light years; with the sun close to the center... Question...

This view however changed in 1922 when the PID control was initially used in industrial applications. Today PID controls are applied in about 95% of the closed loop industrial processes (Ogata, 2008). Controllers are normally used to generate output signals depending on the input signal received. It is important to note that the input signal is usually an error signal. Discussions 1. Reasons for the widespread use of PID controls The use of PID controls has become very popular especially in industrial applications and this can be attributed... Introduction...

### What does Unconscionable Mean

...﻿The term unconscionable is mainly associated with contracts and it is generally defined as a contract which is refused to enforce by the court due to its fundamental unfairness. “Unconscionable” means unreasonably excessive or advantageous and in the context of law it implies that the terms of contract are unreasonably advantageous to one of the parties pursuing the contract. It is important to note that a contract is not deemed to be described as unconscionable just because one party’s term and condition are unfavorable. For a contract to be deemed as unconscionable, it is imperative that the terms of the contract should prove to be shocking to an ordinary person’s conscience. To identify whether that a contract... term unconscionable is...
