Q1(belongs to vectors)
A=3i-2j+5k and B=2i-2j-2k then find A.B(dot product) also calculate the angle between these vectors
Q2) A progressive wave y =0.2sin 2 pie(t/0.5-x/20)m is travelling in a medium find the periodic time and wavelength of the wave
I am posting these questions here because nobody is answering me on any other fourm thanks in advance
