Is 60 a bad grade? This is an above-average score, between 80% and 89% C – this is a grade that rests right in the middle. D – this is still a passing grade, and it’s between 59% and 69% F – this is a failing grade. Is a C+ a bad grade? Don’t kid […]
What are the difficulties in using ground based optical telescope how are they overcome?
What are the difficulties in using ground based optical telescope how are they overcome? Solution. The difficulties faced in using ground based telescopes due to which it does not make good quality observations are: Intensity of light rays reaching the Earth’s surface decreases as some of the light is absorbed by the atmosphere. What other […]
What is the hardest mineral explain why?
What is the hardest mineral explain why? Diamond is the hardest known mineral, Mohs’ 10. Notes: It must be noted that Mohs’ scale is arbitrary and non-linear, i.e. the steps between relative hardness values are not necessarily equal. Rather, it is a method of gauging the relative hardness of a mineral. What is the rarest […]
What do you use to measure diameter?
What do you use to measure diameter? Slide calipers (Digital, Dial or Vernier), outside/ inside micrometers, bore gauges and pin gauges are often used for diameter measurement and control in mechanical engineering applications. The selection of the tool depends on the accuracy requirement and the feature to be measured. What is the most common diameter […]
What is a basic circuit?
What is a basic circuit? A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. Circuits are driven by flows. Which circuit consumes more power? In general, if the […]

Why is glass not a ceramic?
Why is glass not a ceramic? Glass can be called as a type of ceramic. Glass is known to be a non-crystalline material. It is an amorphous solid, which means that it has no long -range order of positioning of its molecules. Ceramic can be termed as an inorganic material. Is ceramic stronger than glass? […]
What is strain structure?
What is strain structure? Strain is the deformation of a material from stress. It is simply a ratio of the change in length to the original length. Deformations that are applied perpendicular to the cross section are normal strains, while deformations applied parallel to the cross section are shear strains. What is structure stress? Structural […]
