17- Soient deux conducteurs ohmiques de résistances R1 =10 22
et R2=2012.
Calculez la résistance du conducteur
ohmique équivalent lorsque ces deux
conducteurs sont groupés;
a- en série
b- en dérivation.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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 .
