A suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation about a question that emerged by observing form the real world.
In this case, the dependent variable is the rate of chemical modification because this variable is modified in the experiment.
In conclusion, a suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.

Answer:
Newton's first and third law of Motion
Explanation:
The laws applying in the example Newton's first and third laws of Motion.
- The first law states that any object at rest (ie. not moving) will stay at rest until it is forced to move by an external force. In this case, said force were the propulsion gases ignited.
- As the hot gases were pushed out from the engine nozzle, there was another force <em>equal in magnitud but opposite in direction</em> (as the gases went down, that force went upwards), said force is directly responsible for the rocket taking off. That is an example of the third law.
Thank you for posting your question here. You just provide a situation, I assume below are the questions:
<span>1. What is the current in the heating element?
</span>
<span>2.What is the resistance of the dryer's heating element at its operating temperature?
</span>
Below are the answers:
1. <span>P = V∙I </span>
<span>I = P/V = 4100 W / 240 V = 17.08 A
</span>
2. <span>Ohm's law: </span>
<span>V = R∙I
</span><span>R = V/I = 240 V / 17.083 A = 14.05 Ω</span>
