Let (x, y) be a point on the terminal side of θ and let r be the distance from (0,0) to (x,y). By the distance formula, the distance from (x,y) to (0,0) is r = √[(x-0)2 + (y-0)2] = √[x2+y2]. So, x2 + y2 = r2 By definition, cosθ = x/r and ...

Define and explain the formula for velocity.Velocity:The velocity of a body relies upon the value of distance traveled as well as the amount of time taken by the body while traveling. The standard measuring unit of the linear velocity of a body is {eq}m/s {/eq}. Newton's equations of...
The next time they are in phase is when the phase difference =2πrad.Hence approximate distance from O for maxima =5cm*4=20cm→ Approximate distance to move from P=20-5=15cm(iv)Approximating using the double-slit equation, ax=λDa=(2.5*10^(-2))(3.2)/(20*10^(-2))=0.4m(ci) ...
