0.85 x 45 x 128 = 4896
Change in energy = specific heat capacity x mass x change in temperature
There are several approaches. The most favourable one (in my opinion) is this one:
1. Asking a question
2. Doing a research (how to answer this question)
3. Creating a hypothesis (NOT a thesis!)
4. Experimenting (to prove the hypothesis)
5. Analysing results from the experiment
6. Writing a thesis
Hello there.
<span>Kaleesha says that not a property of matter . Which statement below best describes why kaleesha is not correct?
</span><span>C) taste is a physical property that can be described</span>
Answer:
I would say since it is still water the stream flow is 0km/h. Especially because he needs the same time upstream as He does down stream.
<span>We can use conservation of energy to solve this question.
The woman increases the potential energy of the box by applying her force over a certain distance.
The work that the woman does is force * distance.
The work the woman does is 25 N * 1 meters = 25 Joules.
25 Joules is the increase in potential energy of the box.
100 * distance of the box = 25
distance of the box = 0.25 meters
Therefore, for every one meter the woman pulls downward, the box rises a distance of 0.25 meters.</span>
