<u>Answer</u>
1. <span>c. convection
</span>2. b. When it is very cold
<u>Explanation</u>
Water like any other liquid transfer heat energy through convection.
When a pot of water is put on a stove, the water at the top gets hot primarily by <span>convection.

A supperconductor is a material that can conduct electric current with no resistance at all.
The supperconductivity can be achieved under cooled temperatures.
Certain materials can become superconductors under what conditions? <u>When it is very cold</u>
# of protons found in the nucleus of an atom of that element,and, therefore identical to the charged nucleus.
Vector explanation is apex and I got 100 on the test and it’s the definition
So I would say (a) water isn't always wet; wetness is always relative to a given substance and/or type of surface and (b) as to why it is wet when it is, presumably the answer is in terms of surface tension.
Answer:
- The formula its
- After 5 years, the computer value its $ 1056
Explanation:
<h3>
Obtaining the formula</h3>
We wish to find a formula that
- Starts at 2816.
- Reach 0 at 8 years.
- Depreciates at a constant rate. m
We can cover all this requisites with a straight-line equation. (an straigh-line its the only curve that has a constant rate of change) :
,
where m its the slope of the line and b give the place where the line intercepts the <em>y</em> axis.
So, we can use this formula with the data from our problem. For the first condition:
So, b = $ 2816.
Now, for the second condition:
So, our formula, finally, its:
<h3>After 5 years</h3>
Now, we just use <em>t = 5 years</em> in our formula
