Answer:
0.000000113 or 1.13*
meters
Explanation:
One nanometer is
meters. So 113 nanometers would be 113*
, or 1.13*
meters. That's expessed on "cientific notation." On the "usual" notation, it will be 0.000000113 meters.
The momentum of each cart is given by:

where
m is the mass of the cart
v is its velocity (at the bottom of the ramp)
To answer the problem, let's calculate the momentum of each of the 4 carts:
1)

2)

3)

4)

Therefore, the cart with greatest momentum is cart 3, so the right answer is
<span>- trial 3, because this trial has a large mass and a large velocity</span>
Answer:
atoms
Explanation:
All matter is made of elementary particles called "atoms".
