What is the efficiency of a cars engine when heat input 2000000 joules and waste heat is 150000 joules?
The efficiency of the car's engine can be calculated using the formula: Efficiency = (Useful energy output / Total energy input) * 100%. In this case, the useful energy output is the heat used for work, which is (2000000 - 150000) Joules. Therefore, the efficiency would be ((2000000 - 150000) / 2000000) * 100% = 92.5%.
What are people that design cars called?
Automotive Engineers
What factors might detract from creating cars with higher fuel efficiency or cars that use alternative energy sources?
There are many factors that may detract from manufacturing more fuel efficient cars. Resources and money are 2 such factors.
What is the efficiency of a cars engine when he input is 200 million Jules and the waste he is 1150000 jewels?
The efficiency of the car's engine is calculated by dividing the useful energy output by the total energy input. In this case, the useful energy output would be 200,000,000 J - 1,150,000 J = 198,850,000 J. Thus, the efficiency would be (198,850,000 J / 200,000,000 J) * 100 = 99.43%.
