If a man drives his car 6km North before making a right hand turn and driving 6 km to the East. then, he makes a left hand turn and travels another 2 km to the north. What is the magnitude of the overall displacement of the driver ?

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
