Engineers are trying to improve a race car. Their goal is to increase the acceleration of the car using the same engine. The change that shows the best application of Newton’s laws of motion to achieve this goal is - option D - decreasing the mass of the car.
When the mass of the car will be less, it will automatically accelerate to higher speed as lighter things move faster than heavier things.
The correct answer is B) Prairies wind erosion usually happen in deserts and coastal sand dunes and beaches, certain land conditions will cause wind erosion in agricultural areas.
So the answer for (a) is basically the enzyme is breaking down the protein (which is the colored part) and this leaves the clear.
For the constants it would be the film and the temperature that the solution is at
For the final question, they could be improved by using more data and multiple trials
