b) justify the stand taken by raghu in your own words.
c) write the energy transformation taking place while raghu rides his bicycle.
Dear Student
a) As Raghu's school is 8 km away so to cover this distance with speed of 8 km/hr
time taken by him is 1 Hr.
As he wants to reach the school 10 mins before then he should leave his house 1 hr 10 min before the school starts.
(b) Raghu has taken a good stand he is really concerned about environment. He choose bicycle over motorcycle to avoid noise and air pollution.
(c) Raghu rides bicycle then chemical energy from body converts into mechanical energy (kinetic energy).
