Two variables, which are directly proportionaql to each other always give a linear relationship.

Can two right angles be complement to each other?

Given the linear equation 2x+3y-8 = 0, write another linear equation in two variables such that the geometrical representation of the pair so formed is : intersecting lines .

Can two acute angles be complement to each other?

Give two examples of simple linear motion.

Which of the following expresson gives the de-Broglie relationship ?

Two parallel wires carryiing current in the same direction attract each other, while two beams of electrons travelling in the same diection repel each other. WHy? Give reasons.

The force exerted to pull a cart is directly proportional to the acceleration produced by the body. Express the statement as a linear equation of two variables and draw the graph of the same by taking the constant mass equal to 6kg. Read from a graph, the force required when the acceleration produced as: 5m/sec^2
