Parallax measurements work by measuring the relative change in position of stars as the earth goes around the sun.
Answer:
speed of apparent on moon = 0.50847° per Hour
speed of apparent movement on Jupiter= 36.36° per Hour
Explanation:
given data
Sun appears to move = 15˝/hr
to find out
How many degrees per hour would the Sun appear to move if we at equator of the Moon and How many degrees per hour would the Sun appear to move if we at the equator on Jupiter
solution
we know that sun is stable it not move but earth is revolving around that sun but it appear sun rise
so movement of sun in sky 360° every day
and time taken = 24 hours
so as we have given
speed of the apparent movement=°/Hour = 15 °/Hour
so
we have given Time taken by the sun to Moon's sky = 29.5 days = 29.5 × 24 = 708 hours
so
speed of apparent on moon =
speed of apparent on moon = 0.50847° per Hour
and
we know Time taken by the sun to Jupiter = 9.9 hr
so
speed of apparent movement on Jupiter=
speed of apparent movement on Jupiter= 36.36° per Hour
Answer:
Explanation:
It used to be very difficult to travel to the west coast before the Panama canal was made. They had to circle the continents. And in the period when they started settling in the Americas the east of the continents was a lot closer to England, Spain, and Portugal. England was closest to the east coast and it was easy to trade and bring supplies there when compared to the west coast.
There is only a single part of the body that is able to get oxygen directly from the air and that is the <u>Cornea</u>.
The cornea is:
- At the front of the eye.
- Is clear which allows for the bending of light which is why blood cannot be there as it would mess with this process.
For this reason, the cornea gets no blood and so has to get its oxygen from the air unlike the rest of the body that gets it from blood supply.
In conclusion, the Cornea is the only part of the body that gets oxygen from the air.
