Metal ores
Explanation:
in an area where subduction has occurred in times past, metal ores are likely to be found.
Metallic ores find subduction zone regions very favorable to crystallize out of a magma.
- Ores have different modes of formation.
- Typically, they are found in hydrothermal vents and black smokers of igneous intrusives.
- These are igneous terrains where metallic sulfides and other minerals crystallize out of magmatic body.
- Metals in magma usually have large sizes and do not partition easily in the melt.
At a subduction zone, partial melting of the subducting plate forces magma into nearby country rock as an intrusive and to the ocean floor where they form black smokers.

Explanation:
when a capacitor and resister are connected in series. charge on its plates decreases exponentially
where,
CHARGE q =15.0 C
INITIAL CHARGE q_0 = 30.0 uc
Resistor R = 20.0 F
capacitor C = 3.00
t = 0.04159 s
Answer:
Explanation:
We're starting a car. We have the fuel in the engine, and when the engine starts, that fuel is converted into power to move the car. The fuel is made of chemicals, right? Propane, gasoline, so on. What kind of energy comes from chemicals? <em>Chemical energy</em>, right?
That fuel is <em>chemical energy</em>, and the energy to move the car must be <em>kinetic/mechanical</em> energy. However, that's not the <em>only</em> source of <em>mechanical energy</em>.
There's another source of <em>mechanical energy</em> here as well: we have an electric battery. What kind of energy is found in a battery? The battery has electricity, and so it has <em>electrical energy</em>. Some of that <em>electrical energy</em> turns into <em>mechanical energy</em> when the car starts up.
But the engine heats up as well, right? There's one more energy that the <em>electrical energy</em> and <em>chemical energy</em> produce here: <em>thermal energy</em>. That's the source of the heat.
I hope this makes sense for you. Have a wonderful day!
