[login to view URL] the several repetitive phenomenon occurring in nature which serve as reasonable time standard? [login to view URL] phenomenon that repeats itself after a certain intervals of time is called repetitive phenomenon whivch can serve as time standard. EXAMPLES: (a)Sunrise and sun set (b)Change of weathers (c)Heart beat of a human person [login to view URL] the drawbacks to use the period of pendulum as time standards? [login to view URL] the time period of the simple pendulum can be expressed as; T= 2 π√l/g But this time period cannot served as reasonable time standard ue to several reasons. REASONS: [login to view URL] period of simple pendulum varies on value of g and g varies with altitude [login to view URL] force of air and support may effect time period [login to view URL] do we find it useful to have two units for the amount of substance ,the kilogram and mole? [login to view URL] we concerned with number of particles we use mole as the unit of the mount of substance But in case when we are not concerned with the number of particles then we may measured the mass in kilogram. [login to view URL] students measured a length of needle of with a scale on which the minimum division is 1mm and record as; (a)0.2145m (b)0.21m (c)0.214m which may correct? ANS.0.214 is correct REASON: The correct record is 0.214 because the least count of scale is 1mm or [login to view URL] length can be preciely measure upto three [login to view URL] 0.214 is correct. [login to view URL] old saying is that “ a chain is only as strong as its weakest links.”what analogous statement can you make regarding to experimental data used in computation? [login to view URL] statement : “A result of experimental data is only as much accurate as its least accurate reading in experimental data” Q6. The period of simple pendulum is measured by a stop watch .what types of errors is possible in time period ? [login to view URL] are two types of possible errors : [login to view URL] error : Stop watch may be faulty (zero error may present or the calibration is incorrect ). [login to view URL] error: Negligence and inexperience of person (at the time to start or stop the stop watch). [login to view URL] a dimensional analysis give any information on constant of propotionality that may appears in algebric expression ?explain . [login to view URL] analysis does not provide any sort of information about the value of constant of propotionality ,it can be determined by experiment For example: For time period of simple pendulum
