The given question is incomplete the options of the compete are:
A. On racecar tracks
B. In real-world conditions
C. In flooded environments
D. On closed courses
Answer: In real world conditions.
Explanation:
Fuel cell vehicles use hydrogen has as a fuel in order to run the car. Unlike the other conventional vehicle that run on fossil fuels and gasoline.
The hydrogen and oxygen combines together in order to power the the motor in the car. The electricity produced by the combination of this runs the car and the waste product is water.
They are also called as electronic cars but the main problem is that it has not been yet tested in the real world. There are many more physiological conditions that differ from place to place in the real world conditions.
Firstly, the cars needs to be tested in the real world and see where there are any advantages and disadvantages over conventional vehicles.
Hence, it is not available to the general public for purchase.
It is estimated that about 1 ft of snow is equal to 1 inch of rain.
Converting inch to cm
1 inch=2.54 cm
Thus, 1 cm=0.393 inch
2.5 cm of rain will be 0.984 inch
now 1 inch of rain is equal to 1 ft of snow, thus, 0.983 inch of rain will be:
0.983 inch of rain=0.983 ft of snow.
Converting ft to cm:
1 ft =30.48 cm
Thus,
0.983 ft= 29.96 cm
Thus, 2.5 cm of rain= 29.96 cm of snow.
Answer:
Aluminium
Explanation:
Ionization energy is the amount of energy needed to remove an electron from a gaseous atom to form a gaseous ion.
The difference between the third and fourth ionization energies is great. This indicates a group III element which is in the third period.
This element is Aluminium (Al)
Many species of plants can absorb heavy metals: those with atomic number greater than 20.
Some are essential for plant growth. These include
Mg, Mn, Fe, Ni, Cu, Zn, and Mo
Plants can absorb other heavy metals, but we don’t know their biological function. Among these are:
Co, Se, Cr, Cd, Ag, Hg, and Pb
Add up all the grams to get 9.96, then divide the amount if each element by the total;
4.56 of Pb divided by 9.96 = 0.4578313 now multiply by 100 and get 45.8% of Pb, then do the same for the rest of the elements, hope this helped <3
