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.
The factor that does not help determine whether a volcanic eruption will be explosive or relatively quiet is the composition of the lava.
On the other hand, the composition of the magma, the temperature of the magma, and the amount of dissolved gases in the magma are quite important for determining this.
For the first question the answer is C. We know this because Dalton considered matter to be composed of very tiny indivisible particles called atoms which means it can't be further subdivided and thus no sub-atomic particles. And for the second question the answer is the Last one: <span>Ernest Rutherford. The rest of them did not give evidence of the existence of a nucleus or gave poor evidence. Hope this helps</span>
