If a car speeds up from 80km/hr to 110km/hr to pass another vehicle in 1.5 min (0.025hrs), what is their acceleration?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
