It starts as a igneous rock and becomes metamorphic then sedimentary
The most likely element is silver
in second place is copper
Compounds
Explanation:
Reactive elements such as alkali metals and halogens are found in nature only as compounds. Such elements are too unstable to remain as stable atoms, therefore they readily combine and form compounds.
- Compounds are formed when two atoms combines together to share electrons.
- They either lose, gain, or share electrons between themselves.
- In the end, they end up becoming more stable.
- This is the reason why atoms combine.
- Unstable elements are very reactive especially alkali metals and halogens.
- On their own, they are unstable and prefers to bond with other atoms in order to gain a measure of stability.
- This is why they are found in combined state in nature.

From my experience, I would say it is true.
Answer:
0.001 s
Explanation:
The force applied on an object is equal to the rate of change of momentum of the object:
where
F is the force applied
is the change in momentum
is the time interval
The change in momentum can be written as
where
m is the mass
v is the final velocity
u is the initial velocity
So the original equation can be written as
In this problem:
m = 5 kg is the mass of the fist
u = 9 m/s is the initial velocity
v = 0 is the final velocity
F = -45,000 N is the force applied (negative because its direction is opposite to the motion)
Therefore, we can re-arrange the equation to solve for the time:
