Gas because liquids and solids volumes don't change from switching containers.
Explanation:
Since its accelerating, the velocity vs time graph is linear
For displacement we need initial velocity (which is zero because it starts from rest) and final velocity (which is calculatee thro acceleration formula
A= (vf - vi)/t
a= vf-0/t
1.25=vf / 7
1.25*7=vf
8.75 = vf
Now for displacement plug all the values in
X = 1/2(vf-vi)/t formula
The displacement (x) is 30.625 m
For part 3, we know new displacement that is 22m , the final and initial velocities are the same so just plug in the values for same formula above
The answer is t = 5.02
Im pretty sure all the answers are correct
Answer:
i think maybe because it has more than 6 or 5 parts.
Well, there's no jet that can travel at that speed ... 14.75 km/s is like 33,000 miles per hour ! But I'll just take the numbers that are there, and work it out just the way the question says.
Distance = (14.75 km/s) x (4.25 hours) x (3,600 sec/hour)
Distance = (14.75 x 4.25 x 3,600) (km-hr-sec/sec-hr)
<em>Distance = 225,675 km</em> (a little more than half-way to the Moon)
