1.	The amplitude of a damped oscillation reduces to one third of its original value a_(0) in 20s. The amplitude of such oscillation after a period of 40s will be……………..
Answer» `a_(0)//9` `a_(0)//6` `a_(0)//2` `a_(0)//27` Solution :In the first 20s, the amplitude reduces to one-third of the ORIGINAL value, i.e., to `a_(0)//3`. In the NEXT 20s, it will reduce to one-third of the reduced value, i.e., to `a_(0)//9`.
