Explanation:
The object stops moving in 5 places (namely B, D, F, H, and position after 28 seconds which isn't marked ).
We know that the object has stopped moving, since its position does not change with the passage of time i.e. at rest.
Jovian planets are also known as gas giants and are the four outer planets Jupiter, Saturn, Uranus and Neptune. Uranus stands out from this group because of the tilt of its axis. Uranus is tilted on its side. Scientists speculate that this tilt may be as a result of a collision with a large body just after the planet was formed. Uranus is tilted 98 degrees compared to earth's 23 degrees.
A) <u>Weight = mass × acceleration (due to gravity) </u>
= 60×9.8
= 588 N
<u>B) Potential energy = mass x gravity x change in height
</u>
1,000 = 60.0 x 9.8 x h
h = 1.7 m
<u>C) Kinetic energyF = potential energyI
</u>
KEF = 1/2mv2
PEI = mgh = 1,000 J
1/2mv2 = 1,000
1/2(60.0)v2 = 1,000
v2 = 33.33
v = 5.77 m/s
You can make sure there's no change in volume by keeping
your gas in a sealed jar with no leaks. Then you can play with
the temperature and the pressure all you want, and you'll know
that the volume is constant.
For 'ideal' gases,
(pressure) times (volume) is proportional to (temperature).
And if volume is constant, then
(pressure) is proportional to (temperature) .
So if you increase the temperature from 110K to 235K,
the pressure increases to (235/110) of where it started.
(400 kPa) x (235/110) = 854.55 kPa. (rounded)
Obviously, choice-b is the right one, but
I don't know where the .46 came from.
