Antoine-Laurent Lavoisier was the first person to report the four element classification system but also ended up including some compounds rather than elements.
Answer:
The column number tells us the amount of valence electron the element has
If the temperature is high there is less water because it evaporates if it is cloudy it is more because it doesn't evaporate
Answer:
a) 32.58 m/s²
b) 161.84 m/s
Explanation:
Initial velocity = u = 0
Final velocity = v = 145 m/s
Time taken = t = 4.45 s
s = Displacement of dragster = 402 m
a = Acceleration


The final velocity is greater than the velocity used to find the average acceleration due to the gear changes. The first gear in a dragster has the most amount of toque which means the acceleration will be maximum. The final gears have less torque which means the acceleration is lower here. The final gears have less acceleration but can spin faster which makes the dragster able to reach higher speeds but slowly.
The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
