Whenever cars, ambulances, trains or aeroplanes go past you notice the changes that the sound makes from a high pitch sound to a low pitch sound. Example if a sound wave is coming from a siren of an approaching ambulance or police officer the sound waves are produced by the siren repeating for then one time. The change in a wave length and a pitch is known as a Doppler effect. Christian doppler described it in 1842 researching what it mainly meant. Doppler effects also happen in light but firstly there is a change in its colour instead of its pitch change. scientist use a device known as spectrometer and they use this device to view various of colours or the light change of them. Edwin Hubble studied the position of dark lines within the spectrum light that was emitted by stars and galaxies. Stars that are moving away at a great speed or rate with spectrum moving towards the red end of the light is called a redshift. The example of the ambulance mainly moves away from us and the faster it goes the louder the sound gets.

RED SHIFT
Light from stars and more distant galaxies is not featureless but has spectral features and many characteristics of the atoms that are in the gases around the stars. When these spectra are researched or examined they are found to be shifted toward the red end of the spectrum. While that shift is called a Doppler shift and it basically outlines that in a fast amount of time all the galaxies are moving away from us.

This led Hubble to the fact that the red shift (recession speed) is proportional to distance and it is mainly called the Hubble’s Law that can be used as a distance-measuring tool itself.

sorry sir i couldn’t do it by yesterday friday because my computer was not working:

Research more about the Hubble Space Telescope. Gather information about
a) Hubble’s involvement in space research

Hubble research on the space has changed our understanding of the space and hubble has contributed to research on subjects as the Solar System to the structure of the most distant galaxies. His involvment has had a big impact in the astronomy from the research of the deep space to the origin of the universe. 

b) What the space telescope does
Hubble Space Telescope known as (HST) is a large space based on observatory which has revolutionized astronomy by providing a deep and clear views of the earths Universe.
c) Where it is

Hubble is located or is found 600 km or (375 miles) above the earths surface. Hubble in comparison is around 384400 or 238860 miles away from the moon.
d) What Hubble’s constant is

Hubbles constant is found mainly by the laws he had which were V=H*R while V symbolizes the galaxy R is the distance away from the earth and H was called the hubble constantand had units known as units of KM/SEC or KM/s?Mpc The hubble constant is used to orbit the universe and is able to find out the age of the universe. 

1.) Describe the term ‘prototype’ and give reasons why it could be used.
 A prototype is an original type or a form of something tjat serves a typical example. A prototype can be used to create a change on an original image to make the image your own by using different computer skills or programs such as photoshop
2.) Discuss another industry other than the car industry that would use prototypes.
The building industries or the kitchen industry might use prototype because they use parts of others kitchens or ideas of other houses to complete their work. I think shoes also provides prototype even though they are not a industry by using a model of another shoe first and then they change the design completely to make a new type of shoe. Another industry that provides prototype things and change things are cloth workers by making one pants out of that they can make more and different style ones.
Provide at least ONE image of a prototype within that industry.

The features of this cars are the following

1. big and bright lights
2. Curved shaped bonit
3. Hektik black big wheels
4. lit a lowow and small car
5. suitable for young tennages
6. colourful colours on the car such as black and silver
7. Lokks like a sports car

The car i have chose this car known as a Shelby Cobra

 1.) There are always TWO sides to a conscience. What would Roger’s conscience be telling him?

2.) Think of an example of Jesus’ teaching and explain how his teachings can help us to make an appropriate decision?

Roger smiths consquence would be telling him dont go in the water and save the boy just think about yourself while the second one is probably telling him go and save the boys live from the water his in danger.

Jesus teaching can help us amke a appropriate decision if we as young people follow him and listen to the words he tells us rather than ignoring him

Being in a relationship with god requires me to do the following:

Trust him and respect the lord’s name

Belief that his the father

Acknowledge that god is my creator and his one who created us humans

1.      I am the lord your god who brought you out of slavery                      I                     You should not have any other god except me 2.      You should not take the word of your lord in vain                              C3.      Remember to keep holy the Sabbath day                                           F4.      Honour your father and mother                                                           H5.      You shall not kill                                                                                 J6.      You shall not commit adultery                                                            B 7.      You shall not steal                                                                              A8.      You shall not bear witness against your neighbours                             G                           9.      You shall not cover your neighbour’s wife                                          D                                           10.  You shall not covet anything that belongs to your neighbours               E  

 The first place to start developing an informed conscience is with the life, teaching and deeds of Jesus Christ. We need to know what he stood for and what he taught so that we can consider this in making our own decisions. Read the following bible passages and identify the moral virtues that Jesus is trying to convey.
