The additive inverse is used to solve equations; equations, in turn, are used to model many real-world situations.
Subtracting an integer is the same as adding the additive inverse. In symbols: a - b = a + (-b), where "-b" is the additive inverse (the opposite) of b.
Additive inverse: change all signs. Multiplicative inverse: flip it over.
(a) Why should we use petrol, diesel and CNG with utmost care?
Jack was sure he'd filled the car with petrol, but he checked the fuel gauge just to be certain.
Tetraethyl lead was previously used as an additive in gasoline to improve engine performance. However, due to its harmful effects on the environment and human health, its use has been largely phased out.
Petrol is a refined product derived from fossil fuels such as crude oil. Crude oil is a fossil fuel formed from the remains of ancient plants and animals over millions of years. Through refining processes, crude oil is converted into various products like petrol for use in vehicles.
Yes. Many internal combustion engines today can and do run perfectly well on 85% alcohol and require just slight modification to run on 100% alcohol.
Some collective nouns to use for petrol are a tank of petrol, a can of petrol, a container of petrol.
i think that we use petrol for vehicles lawn mowers etc. but we use on a daily basis too much petrol we should really cut our oil use
Use no oil additive. It is a waste of money and might actually do harm.
Petrol
No, it is not recommended to put rubbing alcohol in a diesel engine. Rubbing alcohol is not formulated for use as a fuel additive and can cause damage to the engine. It's best to use diesel fuel additives that are specifically designed for diesel engines.
In theory yes but there's very little point in it as you can either get ethanol from crude oil through distilling and cracking through which you can also get diesel and petrol from. You can also make ethanol out of vegetables but again you can also make diesel. The main use of ethanol in running cars I would say is bio-petrol which is just a mixture of petrol and ethanol. All this achieves is less petrol being used. But yes, you can fuel your car on it after modifications but it's more commonly used as an additive to petrol.
Many use standard petrol, some use high octane petrol.
If you use Petrol or Gasoline in a Diesel engine you will destroy that engine. That is why you do not use it.
The majority of cars in the USA use petrol (we call it gasoline).The majority of cars in the USA use petrol (we call it gasoline).
