Some people think a pendulum with a period of 1.00 s can be driven with mental energy or psycho kinetically, because its period is the same as an average heartbeat. True or not, what is the length of such a pendulum?

so period of pendulum is given by T equal to square a two pi squared Would alibi gee said to buy square root El divided by Jin Jin Beon Gravity on We're supposed to find the length so let's do that So length is equal to cheese square, divided by four pi square times the gravity. So let's substitute while the values we know seeing is one second. So it's one square times 9.8 divided by full price square. So when we saw this questions, if you want approximate answers, you can simply do 9.8 is equal to Pi Square. This is true approximately so answer here will be one bullet which is 0.25 But let me do this on my calculator. So this is 9.8 divided by Ford about it. Bye. Hi square. So answer will be 0.24 eight, which is very close. If I if I had assumed I scored by square approximately 1 to 9.8 then answer would be 1/4 which is zero point to fight. So which is a side note. So answer in this case is 0.248 meters. Thank you
