Answer:
In the forward direction and releases carbondioxide gas from backside.
Explanation:
In the forward direction and the carbondioxide gas which is a waste material is removed from the engine at the back. The chemical energy of fuel is converted into mechanical energy with the help of engine which able the car to move in the forward direction so engine is the key component that is responsible for the movement of car.
Answer:
i think by their salinity (the saltiness or amount of salt dissolved in a body of water)

If an an element has an atomic number of 60, then there would me 60 protons.
Something that helps me is APE.
The atomic number is the same as the number of protons and electrons.
Mass of metal piece is 611 g and volume of graduated cylinder is 25.1 mL. When metal piece is placed in the graduated cylinder water level increases to 56.7 mL. The increase in volume is due to volume of metal piece that gets added to the volume of water.
Thus, volume of metal piece can be calculated by subtracting initial volume from the final one.
Thus, volume of metal piece will be 31.6 mL. The mass of metal piece is given 611 g, density of metal can be calculated as follows:
Therefore, density of metal is 19.33 g/mL.
