Answer:
Explanation:
Given that,
A car accelerates negatively from 35m/s to 8m/s in 8s.
We need to find the car's acceleration.
Initial speed, u = 35 m/s
Final speed, v = 8 m/s
Time, t = 8 s
The acceleration of an object is equal to the rate of change of velocity. So,
Put all the values,
So, the acceleration of the car is equal to 
.
Incomplete combustion<span> occurs when the supply of air or oxygen is poor. Water is still </span>produced<span>, but </span>carbon<span> monoxide and </span>carbon<span> are </span>produced<span> instead of </span>carbon dioxide<span>. The </span>carbon<span> is released as soot. </span>Carbon<span> monoxide is a poisonous gas, which is one reason why </span>complete combustion<span> is preferred to </span>incomplete combustion<span>.</span>
