Q  34 the pendulumn of  certain clock has time period 2.04s how fast or slow does the clock run during 24 hrs???

 

 

the pendulumn of colock has time period 2.04sec

now, no. of collision in 1 daY =24*3600/2

                                            =43200

but ,in each oscillation it is slower by (2.04-2.00)=0.04sec

in 1 day it is slower by =43200*0.04

                                   =1728/60

                                   =28.8

 

so the clock runds 28.8 min slower in 1 day
