Answer:


D) Heat flows from the copper cube to the iron cube.  


Step-by-step explanation:


The reason comes from the second law of thermodynamics:


Heat energy will flow spontaneously from an area of high temperature to one of low temperature.


When you bring two objects of different temperature into contact, heat energy always moves from the hotter to the cooler object.


The copper cube is hotter than the iron, so heat flows from the copper cube to the iron cube.


here hope this helps

Mademuasel [1]

The students have conducted an experiment to check their hypothesis on the thermal conductivity of two metals; Aluminum and steel. The experimental observations have been noted, and the next step based on the scientific procedure is to analyze the data.

Analysis of data suggests that; since the length of wax after 10 min is lower in Al than steel, aluminum is a better thermal conductor.

4. If the DNA nitrogen bases were TACCGGAT, how would the other half of
Illusion [34]

Answer:

<u>ATGGCCTA</u>

Explanation:

For this we have to keep in mind that we have a <u>specific relationship between the nitrogen bases</u>:

-) <u>When we have a T (thymine) we will have a bond with A (adenine) and viceversa</u>.

-) <u>When we have C (Cytosine) we will have a bond with G (Guanine) and viceversa</u>.

Therefore if we have: TACCGGAT. We have to put the corresponding nitrogen base, so:

TACCGGAT

<u>ATGGCCTA</u>

<u></u>

I hope it helps!
