दो तरंगों `y_(1) = A sin wt` तथा `y_(2) = A cos wt` में कितने कोण का कलान्तर है ?

The displacement of two particles executing S.H.M are represented by y_(1) = a sin(wt + phi) and y_(2) = a cos w t . The phase difference between the velocities of these particles is

If x = a cos theta + b sin theta and y=a sin theta-b cos theta , the value of x^2+y^2 is: यदि x = a cos theta + b sin theta तथा y=a sin theta-b cos theta है, तो x^2+y^2 का मान ज्ञात करें |

In the triangle, if AB=AC and angle ABC = 72^@ , then angle BAC is: एक त्रिभुज में, यदि AB=AC तथा angle ABC = 72^@ है, तो कोण BAC का मान क्या होगा ?

An AC current is given by i(t) = I_(1)sin wt + I_(2)cos wt . Find the rms value of current.

Two simple harmonic motions are represented as y_(1)=10 "sin" omega " and "y_(2)=5 "sin" wt +5 "cos" omega t The ration of the amplitudes of y_(1) " and " y_(2) is

Two plane longitudinal waves propagate along the x-axis and y-axis: zeta_(1)= a cos (wt-kx) and zeta_(2)=a cos (wt-ky( . Find the wave pattern of the particles in the xy plane.
