The correct option is:
<span>chainsaw, diesel truck, rustling leaves
In fact, this option lists the sounds from greatest amplitude (which means, greatest loudness) to smallest amplitude. For comparison, this is the intensity of the three different sounds:
- chain saw: approximately 120 dB
- diesel truck: approximately 80 dB
- rustling leaves: approximately 20 dB

Use Net Force Equation.
Fnet = F1 + F2 + F3 + F4
In which the following main forces in play are:
F1 = Gravitational Force
F2 = Normal Force
F3 = Thrust Force
F4 = Air resistance
Since this is assumed to happen on a flat surface, the gravitational and normal forces cancel out. So we are left with:
Fnet = F(thrust) + F(air resistance)
Now we can use this equation to solve for the net force.
Fnet = 10N [right] + 7N [left]
Fnet = 10N [right] - 7N [right]
Fnet = 3N [right].
Therefore, the total net force acting on this car would be 3N [right]
Ummm I’m not sure let me do the work

Answer:
<h2>289.9 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 130 × 22.3
We have the final answer as
<h3>289.9 kg.m/s</h3>
Hope this helps you
