Some of the similar ways that medieval university and modern universities are: There were different structures from differente majors, it was arts, science, and engineering which is similar to te universities now. As well money ranks the better place you study. Rich people in those times had the posibility of studying with better teachers like now people who are wealthy go to Ivy League universities.
In addition, they also gave general studies like grammar and vocabulary which is still part of the general studies f your first two years of college.
Answer:
The answer is below
Explanation:
1. Earth's revolution is usually completed after 365 and a quarter days; on the other hand, Moon's revolution is usually completed after 29 and a half days.
2. The revolution of the earth is the movement around the sun, while the revolution of the moon is the movement around the earth.
3. The revolution of the earth makes it appear that the sun rises in the east and set in the west, while the moon revolution only changes how we see or observe the moon at night.

Answer:
Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness.

To give numerical values to this physical property, minerals are ranked along the Mohs scale, which is composed of 10 minerals that have been given arbitrary hardness values. The minerals contained in the scale are shown in the Table; also shown are other materials that approximate the hardness of some of the minerals. As is indicated by the ranking in the scale, if a mineral is scratched by orthoclase but not by apatite, its Mohs hardness is between 5 and 6. In the determination procedure it is necessary to be certain that a scratch is actually made and not just a “chalk” mark that will rub off. If the species being tested is fine-grained, friable, or pulverulent, the test may only loosen grains without testing individual mineral surfaces; thus, certain textures or aggregate forms may hinder or prevent a true hardness determination. For this reason the Mohs test, while greatly facilitating the identification of minerals in the field, is not suitable for accurately gauging the hardness of industrial materials such as steel or ceramics. (For these materials a more precise measure is to be found in the Vickers hardness or Knoop hardness) Another disadvantage of the Mohs scale is that it is not linear; that is, each increment of one in the scale does not indicate a proportional increase in hardness. For instance, the progression from calcite to fluorite (from 3 to 4 on the Mohs scale) reflects an increase in hardness of approximately 25 percent; the progression from corundum to diamond, on the other hand (9 to 10 on the Mohs scale), reflects a hardness increase of more than 300 percent.
