Student A use layer thickness of .1 mm and an infill density of 25%. Student B use a layer thickness of 0.07 mm and an infill density of 45%. Which student will take less time to print the gear? Select one: Stu nt since the ckness of layer is smaller and the infill density is higher. O We can't decide which process takes less time O Student A since the thickness of the layer is larger and the infill density is lower. Student B because thickness is higher than B and the infill density has no effect on the process speed.

- Discuss the importance of microchip manufacturing processes such as photolithography and etching in producing advanced microchips.arrow_forwardMagnetic 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.arrow_forwardGiven that the time constant's theoretical value is 150.8s, and the percentage error is 0.5%, what is the time constant's experimental value?arrow_forward
