Final answer:
In conditions of water or rain, where braking action is reduced, one should apply steady pressure on the brakes until regular braking function is restored. Remember to drive at safe speeds and avoid sudden braking. New vehicle technologies, like regenerative braking in electric and hybrid cars, work differently and can provide additional safety.
Step-by-step explanation:
The question asks about what to do if the braking action of a vehicle is reduced due to water or rain. In such a case, you should apply steady pressure on the brake pedal until you regain regular braking function.
As background information, you should be aware that rain or water can increase the stopping distance of a vehicle. This is because of reduced friction between the tyre and the road surface. As per the high school physics concepts, rain or water can cause a layer of fluid to form between the road and the tyres, which can lead to a phenomenon called hydroplaning. Braking during hydroplaning can cause the car to skid, so a piece of advice is to drive the car at a safe speed and to apply the brakes in a steady and smooth manner.
It's also important to understand the technology of newer cars. The latest hybrid and electric cars use regenerative braking. This technology converts the kinetic and potential energy of the car into electrical energy, which is stored in the battery to be used later.
