What was the Copernican revolution?
Zolol [24]

The Copernican revolution is about the model of the solar system and was given by a polish astronomer. Option C. The discovery that the universe was expanding.

The Copernican Revolution become the paradigm shift from the Ptolemaic model of the heavens, which described the cosmos as having Earth stationery on the center of the universe, to the heliocentric version with the solar on the center of the solar system.

Copernican Revolution, shift the subject of astronomy from a geocentric understanding of the universe, focused around Earth, to heliocentric knowledge, concentrated across the sun, as articulated by the Polish astronomer Nicolaus Copernicus.

This revolution changed the way of thinking of the solar system. Earlier it was thought that earth is in the center of the solar sysytem,i.e; people believed in the geocentric model, but according to Copernicus the solar system has the sun at the center and the remaining planets revolve around it i.e he believed in a heliocentric model.

2 Use the chart to answer the question. Solubility Curves of Various Salts 180 160 140 120 100 80 KNO3 in g NaCl in g KCl in g A
VMariaS [17]

According to the information in the graph, it can be inferred that the amount of solute that will precipitate out of solution at 20°C is 130 grams.

<h3>How to calculate the amount of solute that precipitates out of solution?</h3>

To calculate the amount of solute that precipitates out of solution we must identify the solute data at 80°C and 20°C and identify the difference as shown below:

  • Quantity of solute at 80°C: 170 grams.
  • Quantity of solute at 20°C: 40 grams.

  • 170 grams - 40 grams = 130 grams

According to the above, the amount of solute that will precipitate out of solution due to the change in temperature is 130 grams of KNO3.

Note: This question is incomplete because the graph is missing. Here is the graph

MULTIPLE CHOICE QUESTION
schepotkina [342]

Answer:

(a) The slope of distance-time graph gives the speed of the objects.

           As the slope of object  (B) is the greatest among all, thus  B has the largest speed and hence it is the fastest among all the objects.

(b)  :      As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.

(c)   :      On the y axis  (i.e.  distance line), 7 small represents 4 km

      ∴  1 small line  =  

7

4

​  

=0.57 km

           Position of C at the instant B passes A is  8 km

       

(d)   ;     Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km  

       ∴ Distance traveled by B   =5.14−0=5.14 kmV
