In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.
How long have scientist been genetically modifying humans?
The first successful gene therapy to modify human DNA was in 1990. However, the practice of genetic modification in humans has been controversial and is subject to strict regulations and ethical considerations.
Benjamin franklin a man of reason and science was a good example of the?
Benjamin Franklin, a man of reason and science, is a good example of an American diplomat, statesman and scientist.
What type of scientist studies natural hazards such as volcanoes and tornadoes?
It depends on the type of hazard. Volcanoes are studied by volcanologists, who are a variety of geologist, while tornadoes are studied by meteorologists (weather scientists). Most natural hazards are of a meterological or geological nature, and so will be studied by meteorolgists or geologists.
An object that attracts material containing iron and always faces the same direction when moving freely is lodestone.
----
Nickel and cobalt are two other metals, in addition to iron, that display this type of magnetism. If you wish more information it is available on the wikipedia article entitled 'magnet'.
They have kept the traits that they need in their environment and that same environment has caused them to lose the others. They fit the niche perfectly without any excess traits. Thus saving energy and reproducing more efficiently.
What did Stephen hawking do to affect your lives?
My life... I enjoyed his book, A Short History of Time. References to him on the TV show 'Big Bang Theory' are very entertaining.
Can a tornado turn into a hurricane?
No. Tornadoes are short-lived small scale weather events and are a byproduct of thunderstorms. Hurricanes are long-lived, large scale storm systems.
Why is probability important to a scientist?
Some but not all scientific models are based on the ability to determine the likelihood that a given experimental outcome has happened by chance alone. If you have an accurate understanding of how the variables in the experiment change when nothing in particular is affecting them, then you have a way to establish some confidence that your outcome is the result of your experimental procedure and not the result of purely random events. The experimental 'lingo' is that the researcher has to determine if the 'Null Hypothesis' can be rejected. The Null Hypothesis is that the experimental outcome is not significantly different from what you would expect if the experiment had no effect at all.
As an example, if the probability in the natural world is that some event will happen by chance only one tenth of one percent of the time, then when I observe that event as my experimental outcome, I can be reasonably sure that my procedure has brought about the event; it is so unlikely that it happened by chance. It is not perfect, but few scientific procedures are. This also highlights the importance of replicating studies or of doing meta-analyses of experimental data gathered in many experiments to further reduce the likelihood that observed outcomes are nothing more than chance events.
Why did scientist agree to use one system of measurement?
Scientist agreed on one unit of meaure because for scienctist all over te world could conduct the same experaments without having to worry about getting the wrong meaurements. Also if they had different units when they meet they wouldn't be able to communicate their ideas.
What have scientist learned from volcanoes?
The petrology of igneous rock, the nature of volcanic erutpions themeslves,and, together with all the other processes and events, the nature of plate tectonics.
Also of course, their studies aim to improve eruption prediction, but these processes and their effects are all notoriously difficult to predict, as we saw recently when Italy effectively made it illegal to make a mistake.
Who was isaac newton and what important laws did he discover?
Newton discovered many of the laws and theories that not only furthered our understanding of the universe, but also gave future scientists the tools to discover how to enter space. He discovered gravitational force and established the three Universal Laws of Motion.
What were the circumstances of Harad's life?
grew up in Philadelphia, where he played sandlot baseball as a youngster. He remained an active baseball player when he enrolled at Franklin and Marshall College in Lancaster, Pennsylvania
How many years had Galileo been a prisoner in his home?
Galileo was a prisoner in his home for about 8 years before he died in 1642.
What was Rene descartes significance to the scientific revolution?
Descartes contributed to mathematics and physics, adding to the advances of the scientific revolution. The skepticism expressed in his philosophical theories also influenced thought in the scientific revolution and the Enlightenment.
What does it mean if a scientist fails to rejects a hypothesis?
the hypothesis has not been proven wrong.
Where is Rene Descartes buried?
At Rene Descartes death, Sweden was primarily a Protestant country so he was buried in the graveyard for unbaptized babies, although he was a Catholic. Later, his remains were taken to the Abbey of Saint-German-des-Prés, the oldest church in Paris, where he was laid permanently to rest.

Fleming was only married twice. He passed away in 1955.
Contributions of Rene descartes in the field of mathematics?
One of Descartes simple but important contributions to the field of mathematics is his notation, which made exponents into a superscript after the root. He also came up with the formula for reflection and refraction and the Cartesian plane
What type of visual display should the scientist use?
The scientist should use a circle graph type of visual display. This is because it is the simplest to draw.
