Answer:
Explanation:
Maximum speed is get at maximum power. Let assume that ship travels at constant speed, the expression for power is equal to:
Where 
and 
are the forward force and speed of ship measured in newtons and meters per second, respectively.
The forward force can be determined by clearing it in the expression described above:
Hi there,
Burning fossil fuel should be a cause. Using aerosols also would be a cause.
Smog is an effect of air pollution. As well as acid rain, also I believe that loss of the ozone layer should be an effect of air pollution. I believe that volcano eruptions should be an cause of air pollution
I believe that smog reducing filters should be in the prevention box, as well for using electric cars.

Answer:
the linear speed of the car is 28.83 m/s
Explanation:
Given;
radius of the car, r = 0.33 m
angular speed of each tire, ω = 13.9 rev/s = 13.9 x 2π = 87.35 rad/s
The linear speed of the car is calculated as;
V = ωr
V = 87.35 rad/s x 0.33 m
V = 28.83 m/s
Therefore, the linear speed of the car is 28.83 m/s
Notice that
<em>B</em> = 4<em>i</em> + 6<em>j</em> - 2<em>k</em> = 2 (2<em>i</em> + 3<em>j</em> - <em>k</em>) = 2<em>A</em>
so both vectors point in the same direction and the angle between them is (A) 0°.
