When you want to save money on gasoline, there is nothing more frustrating than having a car that has poor gas mileage. One way to save money on gasoline is by completely eliminating the gasoline factor. Buy a vehicle that does not require gasoline. Electric cars are becoming the top choice for getting rid of the gasoline factor. These cars can be a bit on the pricier side, but not compared to how much money you save in the long run.
What else can I help you with?
What is the efficiency of a car that uses 400000 J of energy from gaseline to make 48000 J of kinetic energy?
The efficiency of the car can be calculated as the ratio of the useful output energy (kinetic energy) to the input energy (energy from gasoline). In this case, the efficiency would be (48000 J / 400000 J) * 100% = 12%. This means that 12% of the energy from gasoline is being converted into kinetic energy.
What is the efficiency of a car if you put in 50 units of energy and it gives you 15 units of energy out?
15/50 = 30%
What is the efficiency of a car's engine when he input is 20000 joules and the waste heat is 15000 joules?
The efficiency of the car's engine is calculated by dividing the useful energy output by the energy input. In this case, the useful energy output would be 5000 joules (20000 input - 15000 waste heat), thus the efficiency would be 5000/20000 = 0.25 or 25%.
What is the difference between high efficiency and low efficiency?
Efficiency describes how well a device transfers one form of energy to another form of usefull energy. High efficiency transforms most of the energy with very little loss. Low efficiency only transforms a small amount into usefull energy and the rest is usually lost to heat energy from friction. For example, a car is a low efficiency device because only a small amount (I forget the actual number. Probably around 50%) of the chemical energy in gasoline actually gets converted to energy of moving the car. The rest is lost to air resistance, friction between all the moving parts & and unused heat out the exhaust pipe.
What type of energy is converted by a solar powered car?
A solar-powered car converts solar energy into electrical energy using photovoltaic cells in its solar panels. This electrical energy powers the car's electric motor, enabling it to move. Additionally, the car may utilize batteries to store excess energy for later use, enhancing its efficiency and range.
Why does a car that runs fuel cells have a similar overall efficiency to a car that runs on petrol?
A car that runs on fuel cells only has a similar overall efficiency to a car that runs on petrol because a car that runs on fuel cells is designed to not pollute the Earth but you need renewable energy resources to generate the electricity which is like the efficiency of the petrol pollution. That was what I put on my homework anywayz. :)
Why does adding oil increases efficiency?
The purpose of adding oil to a car i to lubricate the engine. if the engine is not lubricated there will be much more friction between gears and friction generates heat. because energy is needed to create heat that energy is taken away from the energy that would be propelling the car forward. this causes the efficiency yo drop.
Which describes the energy conversions used to make a car go up or down a street?
When a car goes up a street, chemical energy from the fuel is converted into mechanical energy through the engine, allowing the car to overcome gravitational potential energy. Conversely, when a car goes down a street, gravitational potential energy is converted back into kinetic energy, allowing the car to accelerate without additional fuel consumption. In both cases, energy transformations are crucial for the car's movement and efficiency.
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 type of energy is lost as a car goes up a hill?
As a car goes up a hill, kinetic energy is converted into gravitational potential energy, resulting in a loss of kinetic energy. Additionally, some energy is lost as thermal energy due to friction in the engine and between the tires and the road. This energy loss manifests as heat, reducing the car's overall efficiency as it climbs the incline.
The efficiency of a car depends on the weight of the car?
Efficiency(weight), or E(w)
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%.
