Last two question for the day. brainliest will be given

1. The slope of a velocity curve is acceleration. The slope is negative, but is not constant. The 2nd choice would be better:

... changing negative acceleration

2. 1.5 hours is 1.5×3600 = 5400 seconds, so the change in velocity over that time will be

... 12 m/s² × 5400 s = 64,800 m/s = 6.48×10⁴ m/s

Adding that value to the initial velocity gives

... 2.39×10⁴ m/s + 6.48×10⁴ m/s = 8.87×10⁴ m/s

as the final velocity. Your choice is correct.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
