a) Elapsed time for trial B: 3.0 s

Explanation:

The elapsed time is defined as the difference between the final time and the initial time:

t_{elapsed} = t_{final}-t_{initial}

For trial B, the final time is 4.5 s, while the initial time is 1.5 s, therefore the elapsed time is

t_{elapsed} = 4.5 s-1.5 s=3.0 s


b) Average speed for trial B: 1.3 m/s

Explanation:

The average speed is given by the distance traveled divided by the elapsed time:

v=\frac{d}{t_{elapsed}}

For trial B, the distance traveled is d=4.0 m, while the elapsed time is t=3.0s, therefore the average speed is

v=\frac{4.0 m}{3.0 s}=1.3 m/s

Answer:

John Dalton

Explanation:

Dalton's atomic theory was the foundation for a new understanding of chemical structures. He proposed that matter was constituted by indivisible and indestructible particles "atoms." He theorized that all atoms of a particular substance were equal, and the atoms of different substances had atoms of different sizes and masses.

He also proposed that all compounds of elements were combinations of elements but in a very precise ratio.
