Gamma rays and X rays are both dangerous to living cells because they are very penetrating and pass easily through flesh, harming the DNA of cells.
The density of petrol is 0.8g cm3 which is the same as 800g per litre The mass of petrol supplied is 4Kg = 4000 grams =4000/0.8 = 5000cm3 5000cm3 = 5 litres of petrol. Answered by the longfield BTEC boys.

The density of petrol varies, depending on its composition. 20 thousand litres would weigh between 14200 kg and 15400 kg.
because it has very less density.
because the density of oak wood is less than the water and greater than the petrol.
The density of petroleum diesel is about 0.85 kg/l whereas petrol (gasoline) has a density of about 0.72 kg/l, about 15% less
Many hydrocarbons such as petrol has an Sg of about .7
No, the density of frozen water is less than petrol's.
3.78litters
13J energy is stored in petrol,
About 100 to 150
A full tank of petrol is worth as much as a full tank of petrol in any other car.
