Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known

What is the difference between hypothesis and law? A hypothesis is a statement‚ put forth on the basis of reasoning‚ about the things that are being studied. A hypothesis is an educated guess based on past scientific studies and previous experiments. It is not just a random guess. Observation is followed by a hypothesis. For example ‘Plants need sunlight to grow’ can be a hypothesis. It is formulated by taking into account all the observations that are know about the phenomenon under investigation

Null Hypothesis (McMillan‚ 2012‚ p. 49): A null hypothesis states that no significant statistical relationship or difference exists between the groups that are being compared in astudy. This term relates to all of the studies I read for my research study analyses. They all compared the academic achievement of high school athletes and non-athletes in some way or another. While the null hypotheses were not explicitly mentioned in the studies‚ they all would have been something along the lines of

Hypothesis Testing and Nursing Hypothesis testing is a method of making decisions using data from scientific study. In statistics‚ a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone‚ according to pre-determined threshold probability‚ the significance level. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect based on how
