Testable: Able to be tested or tried.
<em>ex. An example of a testable hypothesis is, Students who attend class more have higher grades, while those who skip have lower grades. </em>
Data: Data is the items of information that represent our analyze, or our findings in an experiment.
<em>ex. An example of Data, is the results of information collected for a research paper.</em>
Evidence: Evidence is information that helps show whether a proposed idea is valid.
<em>ex. We can use evidence to help support our point and strengthen our findings with reasoning.</em>
Theory: Theory is an explanation of something in the natural world that can be tested and gives us the same results each time. A proven hypothesis.
<em>ex. Examples of scientific theories are gravitation, evolution, and plate tectonics. </em>
Hypothesis: A hypothesis is a theory or question that can be tested through study and experimentation. It has more reasoning to it than a simple guess, but not enough information to be a theory.
<em>ex. An example of a possible hypothesis is, If we play music while working on homework, the participant's perfomance will increase.</em>
Do you have a chart or something that goes with it?
True. Because you can touch it and it's physically real.
Answer:
0.91 J
Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the lemming in this problem, when he jumps, we have:
m = 0.0780 kg is the mass
v = 4.84 m/s is the speed
Substituting into the equation, we find:
Answer:
255 metres
Explanation:
The answer to thi question is actually quite simple. Since the car goes for 3.4 seconds, and it goes 75 metres every second, the answer is just 3.4 multiplied by 75 Metres.
