Answer:
The cyclist’s displacement is +5 m.
Explanation:
We have, A cyclist starts at a position of origin. He takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.
It is required to find the cyclist’s displacement. Displacement of an object is the shortest path covered by it or it is given by the difference of final to the initial position.
Finally, he cycles west to a position of +5 m. Distance between final and initial position is +5 m.
Hence, the cyclist’s displacement is +5 m.
They both can expel water from the polymer network
Answer:
With an experiment following the scientific method
Explanation:
The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis. Critical thinking is a key component of the scientific method. Without it, you cannot use logic to come to conclusions.
