CBSE Class 11-science Answered

what is meant by phase and phase difference?also please let me know how to determine wether an equation is SHM or not and at last,what is meant by resonance ???

Resonance:
Resonance is the tendency of a system to oscillate at maximum amplitude at certain frequencies, known as the system's resonance frequencies. At  these frequencies, even small periodic driving forces can produce large amplitude vibrations.
 
When natural frequency of the system equals the applied frequency, system vibrates with maximum amplitude.
 
Kindly ask seperate questions as seperate query.
