Magnetic resonance imaging (MRI) is a medical imaging technique that located in hospitals and radiology centers. MRI uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body. (i) MRI system operators must make sure not to carry any metallic objects when they enter the room that house the MRI, even when the machine is not operating. Give the reason. (ii) What happens if a magnet was hitted with a hammer repeatedly? Explain your answer. Robots are used in automobile industries to weld two components at specific locations. Thus, the end position of the robot arms must be determined accurately in order to weld the components at the precise position. In selecting a proper material for the robot arms design, identify the factors must be considered for this application.

Suppose NASA sent a robotic craft to explore the deep oceans of Jupiter’s moon, Europa (assume the ocean water has an index of refraction 1.34) . In an attempt to be discrete, NASA applies a coating to the submarine-like craft, to make it indetectable to any creatures in the ocean who can see light with a wavelength of 1200nm. The coating material has anindex of refraction of 1.25.a) Draw a clear physics diagram of the problem.b) Technology only allows for coatings to be 1 micrometer or thicker. What is the thinnest coating that can be applied to the craft to make it invisible at 1200nm.
