QI) Fill the blanks with suitable expression
The given line graph 1 the sutrogen exide emuniens from buses. lorries, petrol can and
daesel cars. It casn be swen trom the graph that the manimm eminsuns are trom buses and the emissions
wary with the spend of the vehicle
Overall emisnions from lorries and buses follew a 2-patterm and those from diesel ant petrel
cas tollow a pattem.
AMa spred of 4kgah, buses produce 0 gkan emaama. However, as the speed ofl the bas
iterase to 60 kgai, the emisnions decrease gradsally and seadi a little over 25 ghm. It is isteresting to
note that if fle speed of the bus goes bryond 60 kpli, te euasiona again Iegin to rie, and at a upeed of
130 kph the emimioana are ver km. Larrien also shusw a nimilar pattem lut the averall emamans
are lower than that trom buses.
Anotives point of datferetnoe is that emisnionu deciease till the speed of 9Chph and only ater that
begin to tie again. The vaissionu from dirsel car and peteal car show a simular patten arud also do tet
shmr much variation with speed. Eminninna from diesel car are the least and hover areund -km
ad those trom petrel car are arouid 10g/han.
