The new acceleration is
Explanation:
We can answer this problem by applying Newton's second law, which states that:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
The equation can be rewritten as
In this problem, the initial acceleration is
Later:
- The net force is tripled:
- The mass is halved:
Therefore, the new acceleration is:
which means that the new acceleration is 6 times the original acceleration, therefore

A fault breaks through sedimentary layers.
Igneous rock forms between sedimentary layers.
Explanation:
The principle of cross-cutting relationships is useful in determining relative ages where a fault breaks through sedimentary layers and when igneous rocks form between sedimentary layers.
- The principle of cross-cutting relationships suggest that a fault and an intrusion are younger than the rocks they cut through.
- A rock displacement and joints when seen in sedimentary rocks are obviously older than the rocks they cut through.
- Igneous intrusions between rock layers are also younger than the beds they cut through.
- In tilted beds, we use the law of original horizontality to resolve it.

Answer:
A
I think I've read this passage before
Answer:
the law of motion
Explanation:
because the wheels are moving it means motion i am not sure which number law it is but I believe that it is 2nd but u should look it up to be safe
