A blue flame is a manifestation that the combustion process is complete where there are no formation of carbon monoxide. On the other hand, a yellow flame represents an in complete combustion. Generally, a blue flame is much hotter as compared to a yellow flame so it heat things up faster. Also, it is a much cleaner flame as it does not produce soot which leaves a black residue on the material being heated.
Momentum is described as the result of the calculation of mass multiplied by that thing's velocity.
<span>
In equational formula we can write it: </span>
<span>
P (momentum) = m(mass) * v(velocity) </span>
so to find the mass, revert the equation:
<span>
P = m v </span>
m = P / v
now for the value entry,
<span>
m = 2.5 * 10^4 kgm/s / 30 m/s </span>
<span>
m = 8,3 * 10^2 kilograms

Answer:
A star that always remains above your horizon and appears to rotate around the celestial pole.
Explanation:
A) a star that is close to the north celestial pole: a circumpolar star could be close to the north celestial pole, but this answer is omitting the south celestial pole.
B) a star that is close to the south celestial pole: a circumpolar star could be close to the south celestial pole, but this answer is omitting the north celestial pole.
C) a star that always remains above your horizon and appears to rotate around the celestial pole: this is the definition of a circumpolar star.
D) a star that makes a daily circle around the celestial sphere: every star does this.
E) a star that is visible from the Arctic or Antarctic circles
: there are many starts visible from there that are not circumpolar.
The force of the collisions creates pressure on the container. ... Explain why atmospheric pressure changes as depth changes. Atmospheric pressure increases as depth increases because at lower levels of the atmosphere, there is more air above that is being pulled down by gravitational force.
44 x 12. I got the 12 from the total of 12 months in a year.
44 > 40
x
12 > 10
----------
The way my teacher taught me how to estimate is look at the neighbor to 44 and 12. The only time 44 can become 50, is when the neighbor is 5 or up. Same thing for 12. Now, multiply 40 and 10.
40 x 10 = 400.
Therefore, your estimate is 400.
The real answer is 520 breaths.
