Observing the universe
The time that is takes light to travel in one year.
What is a light year?
Valence electrons connect to other atoms.
Why do atoms bond?
An organism which is adapted to live in an extreme environment.
What is an extremophile?
Used by the earliest rockets.
What is solid fuel?
This telescope uses lenses.
What is a refracting telescope?
The number of waves that pass a point every second.
What is the frequency of a wave?
Tardigrades from this when they are in a dormant stage.
What is a Tun?
This organism lives in a cow's stomach and creates energy from gases.
What is a "Methanogen"?
Kerosene, liquid hydrogen and liquid oxygen.
What are common liquid rocket fuels?
When fuel tanks separate from the rockets.
What is rocket stage separation?
This telescope uses mirrors.
What is a reflecting telescope?
An organism that uses chemicals in the environment to provide energy.
What is a Chemoautotroph?
This organism lives in deep sea hot springs.
What is a "Chemoautotroph"?
Centre of Mass is above the Centre of Pressure.
What is required for a stable rocket launch?
Hubble's constant confirms this theory of the universe's origins.
The Big Bang Theory.
This happens when an electron changes to a lower energy state in an atom.
When is energy/light given off by an atom?
Survived in space and began to consume the outside and windows of the space station.
What is the 'space fungi'?
The equation used to calculate the rocket apogee from the altitude angle.
What is Opposite = Tan (theta) times adjacent?
The four forces experienced by a rocket.
What are weight, thrust, lift and drag?
To reduce bacteria in food on the space station.
Why is all food going to the space station preserved?
When an emission spectra has a longer wavelength, indicating it is moving away from Earth.
What is redshift?
Cell theory.
What are the three rules of 'life' called?
The medicine could help astronauts increase bone density in space.
What are the medical applications of the fungi found on the space station?
By working out the surface area of the rocket.
How do you calculate Centre of Pressure?
v = H d
How is Hubble's constant calculated?
