The simplest type of motion is the motion along a straight line. Two different quantities Distance and Displacement are used to describe the overall motion of an object and to locate its final position...
Suppose an object having mass m has an initial velocity u and after certain time t it attains a velocity v. Now momentum P1=mu and P2=mv So change in momentum =P2-P1=mv-mu =m(v-u) So the rate of change...
QUESTION Q) Let ‘A’ = (x^2 - 3x + 4) / (x^2 + 3x + 4) Then the minimum value that ‘A’ can undertake for all real values of x, lies in which of these intervals? A) (-inf, -2) B)...
