Answer:
The same
Explanation:
The change in momentum of each cart is equal to the impulse given by the force applied on the cart:
where
F is the force applied
is the time during which the force is applied
The force applied to both carts (F) is the same, as well as the time (). This means that the change in momentum, 
, is the same for both carts. But both carts start from rest (momentum = 0): this means that at the end, both carts will have exactly same momentum.
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

A baseball is accelerated downward at 9.8 m/s^2 when the only vertical force acting upon the baseball is gravity.
It’s more dense than air and less dense than liquid!
