The 1848 revolution of the liberals:

The 1848 revolution was led by the educated middle class along with the poor, unemployed, starving peasants and workers in many European countries for fulfilling their demands of constitutionalism with national unification.

Following were the political, social and economic ideas supported by the liberals:

Political ideas: The ideology of liberalism supported the ideas of national unity and abolition of aristocratic privileges. In German regions, a large number of political associations whose members were middle-class professionals, businessman and prosperous artisans came together in the city of Frankfurt and decided to vote for all German National Assembly.
Social ideas: A large number of women had participated actively and formed their own political associations founded a newspaper, took part in political meetings and struggled for the right to vote. They supported freedom for the individual and the idea of equality of all before the law.
Economic ideas: Liberalism stood for the freedom of markets and the abolition of state-imposed restrictions on the movement of goods and capital.

It is given in the question that, The vertices of a parallelogram PQRS taken in order are P(3,4), Q(-2,3) and R(-3,-2) Let, the fourth vertices is S (x , y). The parallelogram's PQRS's vertices, listed in order. Because of this, a parallelogram's diagonals are split in half. We know that the diagonals of a parallelogram bisects with each other. ∴ Coordinates of the PR's midpoint = coordinates for QS's midpoint \begin{gathered}(\frac{3-3}{2} ,\frac{4-2}{2} ) = (\frac{-2+x}{2}, \frac{3+y}{2} )\\ (0,1) = (\frac{-2+x}{2}, \frac{3+y}{2} )\end{gathered}(23−3,24−2)=(2−2+x,23+y)(0,1)=(2−2+x,23+y) Now, 0 = \frac{-2+x}{2}0=2−2+x .............(1) Simplify the equation, \begin{gathered}0 = -2+x\\x=2\end{gathered}0=−2+xx=2 Again, 1=\frac{3+y}{2}1=23+y ...............(2) Simplify the equation, \begin{gathered}1=\frac{3+y}{2}\\2=3+y\\y=-1\end{gathered}1=23+y2=3+yy=−1 the coordinates of its fourth vertex S are (2,-1).

Preeti Dabral 3 years, 1 month ago

Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO₃). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral. Limestone originates in wet areas which mean it could also be composed of shells and waste matter from organisms.

why do sky appear dark to an astronaut

Posted by Prachi Chhikara 3 years, 1 month ago

CBSE > Class 10 > Science

2 answers

Preeti Dabral 3 years, 1 month ago

Blue colour of the sky as seen from earth surface is on the account of scattering of light of shorter wavelength by particles present in the atmosphere of the earth. If the earth had no atmosphere, there would not have been any scattering and sky would have looked dark. When an astronaut is in his spacecraft, he is present above the atmosphere of earth, from where the sky appears dark to him because there is no scattering of light there.
