Answer:
Fluid friction.
Explanation:
Friction can be defined as a force that resists the relative motion of two objects when there surface comes in contact. Thus, it prevents two surface from easily sliding over or slipping across one another. Also, friction usually reduces the efficiency and mechanical advantage of machines but can be reduced through lubrication.
Generally, there are four (4) main types of friction and these includes;
I. Static friction.
II. Rolling friction.
III. Sliding friction.
IV. Fluid friction.
Fluid friction can be defined as a type of friction that acts on objects moving through a liquid or gas. A fluid refers to any physical substance that can flow and is able to take the shape of a container.
Answer: The objective of this analysis is to review a spectrum of functional brain imaging technologies to identify whether there are any imaging modalities that are more effective than others for various brain pathology conditions. This evidence-based analysis reviews magnetoencephalography (MEG), magnetic resonance spectroscopy (MRS), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI) for the diagnosis or surgical management of the following conditions: Alzheimer’s disease (AD), brain tumors, epilepsy, multiple sclerosis (MS), and Parkinson’s disease (PD).
The reporter interpreted the findings correctly. In Ontario, there will be an estimated 950 new cases and 580 deaths due to brain cancer in 2006. Treatments for brain tumors include surgery and radiation therapy. However, one of the limitations of radiation therapy is that it damages tissue though necrosis and scarring. Computed tomography (CT) and magnetic resonance imaging (MRI) may not distinguish between radiation effects and resistant tissue, creating a potential role for functional brain imaging.
Explanation:
Answer:
The Zionist Movement.
Explanation:
The birth and actions of the Zionist Movement were spurred by two things: the Jewish beliefs regarding a return to their ancient homeland and the anti-Semitic events in Europe in the early 20th century. The founder is Theodore Herzl. Its origins are in Eastern and Central Europe in the last years of the 19th century.
