Technician a says that a defective spark plug wire can cause an engine misfire. Technician b says that a defective spark plug can cause an engine misfire. In this case, both technicians are correct.
Technician A is correct, because, Bad spark plug wires can interfere with the electrical current flowing to the engine, making it difficult for the engine to complete the combustion cycle. An incomplete combustion cycle can cause an engine to misfire, also
Technician B is correct because, Dirty spark plugs can cause misfires as well as burned engine oil can prevent the plugs from creating the sparks needed to ignite the fuel after it goes into the cylinder. Old spark plugs can simply break and fail to produce a spark. A broken spark plug is a simple fix, just replace it.

From the given information, we don't know. All we can tell is the net effect of all the changes during those 4 seconds ... the "averages".
The average change in speed is an increase of 72 km/hr (20 m/s) during that time.
The average acceleration is a constant 18 km/hr/sec (5 m/s^2) during the same time.
But both the speed and the acceleration may have gone up or down many times during the 4 seconds.
Assertion(A):'
There is danger of a vehicle skidding on a wet road.
<h3>Reason (R) : </h3>
The tyres of the vehicle lose their grip on the road due to increase in friction due to presence of water on the road.
Answer:-
- Assertion is true
- Reason is true
- Reason is the perfect explanation of Assertion
Cause of high probability of accidents of loaded vehicles in over speed effected by momentum on the basis of first law of motion.
<h3>What does Newton's first law say?</h3>
When we are standing inside a bus and it brakes abruptly, due to inertia, we are thrown forward. When a car is going around a curve it is necessary for a force to act, otherwise the car will go in a straight line.
the cause of high probability of accidents of loaded vehicles in over speed occurs large amount of momentum.
