<span>The answer is heterogeneous mixture. A heterogeneous mixture is a combination of substances that are combined physically but not chemically. This is a mixture that is not uniform in composition. Its components can easily be separated from one another. For example, pile of soil is a heterogeneous mixture because it consists of different components.</span>
Answer:
This is an astrophysics question and we will use the following formulas to get the time 't' it will take the sun to move a distance equals to it's own diameter 'd'.
Recal:
ω = 2π rads,
Then the earth's angular velocity will be,
ω = (2πrads / (24h * 3600s/h)) = 7.27x10⁻⁵ rad/s
and note that the Angular Acceleration
∅= ω*t
9.28x10⁻³rads = 7.27x10⁻⁵rads x t
t = 127 s
Hence, the time (in seconds) it take for the sun to move a distance equal to its own diameter = 127seconds
<h2>
Answer: The volume will triple (increase by a factor of three).</h2>
Explanation:
The expression for an Ideal Gas is:
(1)
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
Finding :
(2)
If we are told the the amount of gas and pressure remain constant, but we increase the temperature by a factor of three; we will have to rewrite (2) with the new temperature :
(3)
(4)
Now, if we compare (2) with (4), it is clearly noticeable the volume of the gas has increased by a factor of 3.
Answer:
during a solar eclipse the earth and the sun are lined up so that the moon blocks the sun from our veiw.
the reason the east coast doesn't see it at the same time as the west coast is because of the rotation of the earth and the movement of the moon
hope this helps. :)
Yes, the phases should be visible. The phases are,
New moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning cresent, repeat
