A) According to the nebular theory, the Solar System formed from a huge gaseous nebula which at a certain point was perturbated. Atoms and molecules started colliding, forming planetesimals (a sort of big rocks). The planetesimals were attracted to each other by gravity, forming bigger warm almost spherical objects called protoplanets, which at the end cooled down forming planets.
Therefore the correct answer is "all of the above".
b) The planets closer to the Sun were (and still are) subject to higher temperatures, due to their close distance to the Sun. In these conditions, rocky materials undergo condensation, while iced gaseous materials undergo vaporization. In the outer parts of the Solar System temperatures are too low to allow these transformations.
The correct answer is again "all of the above".
Since the process occurs at constant pressure, the work done by the gas on the piston is given by
where
W is the work
p is the pressure
is the final volume
is the initial volume
In our problem, we have
(where the negative sign means the work is done by the piston on the gas)
We can re-arrange the previous equation and use these values to find the pressure:
Answer:
Below in bold.
Explanation:
1. Speed = distance / time
= 100 / 9.84
= 10.16 m/s.
Speed = 200/19.32 = 10.35 m/s.
Speed = 400/43.49 = 9.20 m/s.
White light is composed of light of different wavelengths (colors) i.e. violet, indigo, blue, green, yellow and red.
Yes we do. Without scientific notation, we would be in deep do-do
whenever we need to tell somebody else the mass of the sun, the
number of electrons in 1 coulomb of charge, the frequency of our
favorite radio station, or the wavelength of orange light.
