We are humans, therefore, we live in a society. There are different people next to our homes. They help us in difficulties. And we also help them in need. Thus, neighbourhood is the place where we share happiness and sorrow. We exchange goods .....

The gravitational force depends inversely upon the square of the distance between two objects from their centres.  i.e. F ∝ 1/d2 ----------- 1 So, when the earth is at postion Apoapsis, the distance between earth and the sun .....

Product of HCF and LCM = 384  or, 8 ⨉ LCM = 384 or, LCM = 48                 .....

Here,  Given that, Product of two numbers = 300 LCM of two numbers = 60 We know that,  Product of two numbers = HCF x LCM Or, 300 = HCF x 60 Or, 300/60 = HCF Or, 5 = HCF.   Therefore the HCF between the two numbers is .....

Rest and motion are relative term.  One object seen as on rest from one point can be seen to be in motion from another point. For example, mountains are seen to be in rest from earth, but they can be seen to be in motion from moon. We see .....

Here, 3a + 4a + 5a = 180o     ( Being angles of straight line) or, 12a = 180 or, a = 180/12   or, a = 15o Now you can get the required angles by placing the value of 'a' in the given angles. 3a = 3 x 15 = 45o 4a = 4 .....

Here, b = 50o (vertically opposite angle) a = c (vertically opposite angle ) ∴ c + a + b + 50o = 360o ( complete angle ) or, 2a + 50o + 50o = 360o  or, 2a = 360o - 100o ∴ a = c = .....
