In theory, any force will do. According to Newton's Second Law (F=ma; that is, force = mass x acceleration), a smaller force will take longer to slow it down.
It would take longer for the house to cool down because hot air can heat up the house faster
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
No. At least, not yet. For information about certain progress in this are, and ongoing research, take a look at the Wikipedia article - or other sources - on "Theory of everything".
because with a longer chain you are giving the hammer momentum so it will take more strength to move
Theory-practice-theory take existing theory in education, apply to distance learning, develop new theory Practice-research-theory see what is happening in distance learning, submit to research, develop theory from results Theory-theory-research/practice build on an initial theory to develop a second theory, then apply and test it
What is a hypothesis? (plural: hypotheses) I'll take Science Experiment terms for $1,000, Alex.
they think really hard..
It varies from years to forever (or never).
150 years, after microscopes were invented.
Form a question. Develop a hypothesis. Make observations. Conduct controlled experiments. Make predictions. Collect data. Analyze data. Develop a conclusion.
As long as you haven't scientifically proven that a statement you make or a phenomenon you describe is actually true and repeatable all over the world, then you may call this statement a hypothesis. It is something you personally believe in, but the rest of the world will not believe you unless you test your hypothesis and prove it right. (Needless to say, if your test results prove your hypothesis wrong, then you need to start over and rephrase the hypothesis.) After repeated empirical testing with getting the same results every time, and when you believe your hypothesis is right, then you might announce your findings to the world by presenting a theory. This theory is accepted by your peers, but only if they get the same results under similar conditions in their own labs. And if your theory is truly revolutionary, resulting in a so-called change of paradigm, then you may expect a Nobel prize at some point.Answer 2:A hypothesis is a guess or proposed explanation for an observed phenomenon. It's a starting point for further investigation. A theory is much more substantial. To become a theory, after the hypothesis is proposed it is tested in various ways. For example, theories can be used to make predictions which can then be tested. And, a after testing a theory has not been contradicted by these tests.
190 years passed between the discovery of cells and when the third cell theory was added.
More scientists worked on finding out about cells
It is usually the more intelligent or bigger animals that take longer because there is a much bigger teaching element involved. Some animals are just bigger and take longer to develop.
The way scientists form a hypothesis is there is something called the scientific method. You establish your question or problem first. Next, you research it. You take your hypothesis, theory, or prediction of what is going to happen from your research. Then, its testing time!A scientist makes an educated guess about the answer to a scientific question.
After observational evidence is published to support a hypothesis, particularly one that challenges conventional wisdom, scientists begin to analyze the evidence to see if there is some error. This analysis can take weeks to months; if other scientists try to replicate the experiment, it can take a few years. If the initial observations -- and the conclusions that can be drawn from them -- are shown to be correct, scientists (sometimes grudgingly) cease to refer to the original idea as a hypothesis and start to call it a theory.
