Answer:
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Answer:
x = 1.58 m
, As this distance is much less than the distance to Ferdinand, it doesn't get wet
Explanation:
This problem can take a small amount of water as if it were a particular to analyze if it reaches where Ferdinand is (x = 10m), with this analysis we see that we can treat this problem as a projectile launch.
Let's look for the time it takes to reach the ground, the water initially comes out horizontally, so the initial vertical speed is zero (I go = 0)
y = t - ½ g t²
y = 0 - ½ g t²
t² = -2y / g
t² = - 2 (-1.0) /9.81
t = 0.452 s
with this time we calculate the horizontal distance traveled
x = v₀ₓ t
x = 3.5 0.452
x = 1.58 m
As this distance is much less than the distance to Ferdinand, it doesn't get wet
Forgot to measure the volume in the beginning so the student could tell the difference
