Two pendulums begin to swing simultaneously. If the ratio of the frequency of oscillations of the two is 7 : 8, then the ratio of lengths of the two pendulums will be

Two pendulums differ in lengths by 22m . They oscillate at the same place so that one of then makes 30 oscillations and the other makes 36 oscillations during the same time. The length ( in cm) of the pendulum are :

Two simple pendulum with heavy bobs-one using iron wire and the other aluminimum wire are excited simultaneously. It is found that when the first pendulum completes 1000 oscillations the other completes 1001. When the temperature is raised by t^(@)C , it is found that the two pendulums now oscillate together. If he coefficients of thermal expansion of iron and aluminimum are 10 xx 10^(-6)//^(@)C and 30 xx 10^(-6)//^(@)C then the value of t is :
