Many trials are taken and averaged in an experiment to reduce the measurement error.
A great manner by which error is reduced or to enhance the accuracy of measurement is to take many measurements and compute their average. In other terms, one attain accuracy via averaging.
This also validates the repeatability of the measurement. The kinds of experimental error include mistakes in data entry, human error, mistakes in the design of the experiment, or systematic error, or random error due to environmental circumstances.
Well we know that a microscope is used to see things we cant see like organism's so they can study those small creatures and learn
Answer:
In creating this list, one will have to start from the atom (which is the smallest in the list) to the giant polymer (which is the largest in the group). The arrangement below will also be based on there molecular weight.
oxygen molecule (this is the first because it is an atom)
water molecule (this is lighter in weight than carbon dioxide)
carbon dioxide
amino acid molecule (most amino acids have a lesser molecular weight than glucose)
glucose (has a molecular weight of 180.156 g/mol)
protein molecule (several proteins have a lesser molecular weight than starch)
starch molecule (has a molecular weight of 359.33 g/mol)
Explanation:
Once massive stars reach the red giant phase, the core temperature continues to increase as carbon atoms are formed from the fusion of helium atoms. Gravity continues to pull together the carbon atoms in the core until the temperature reaches 600,000,000 degrees Celsius. At this temperature, carbon atoms form heavy elements such as oxygen and nitrogen. The fusion and production of heavy elements continues until iron starts to form. At this point, fusion stops and the iron atoms start to absorb energy. This energy is eventually released in a powerful explosion called a supernova. A supernova can light the sky up for weeks. The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion. The core of a massive star that is 1.5 to 4 times as massive as our Sun ends up as a neutron star after the supernova. Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars. The core of a massive star that has 10 or more times the mass of our Sun remains massive after the supernova. No nuclear fusion is taking place to support the core, so it is swallowed by its own gravity. It has now become a black hole which readily swallows any matter and energy that comes too near it. Some black holes have companion stars whose gases they pull off. As the gases are pulled down into the black hole, they heat up and give off energy in the form of X-rays. Black holes are detected by the X-rays which are given off as matter falls down into the hole.
