For this case we must do a conversion. By definition we have to:
1 inch equals 2.54 centimeters
1 day equals 24 hours.
So, we have:![18 \frac {in} {day} * \frac {1} {24} \frac {day} {h} * \frac {2.54} {1} \frac {cm} {in} =](https://tex.z-dn.net/?f=18%20%5Cfrac%20%7Bin%7D%20%7Bday%7D%20%2A%20%5Cfrac%20%7B1%7D%20%7B24%7D%20%5Cfrac%20%7Bday%7D%20%7Bh%7D%20%2A%20%5Cfrac%20%7B2.54%7D%20%7B1%7D%20%5Cfrac%20%7Bcm%7D%20%7Bin%7D%20%3D)
Canceling units we have:
![\frac {18 * 1 * 2.54} {24 * 1} \frac {cm} {h} =\\\frac {45.72} {24}\frac {cm} {h} =](https://tex.z-dn.net/?f=%5Cfrac%20%7B18%20%2A%201%20%2A%202.54%7D%20%7B24%20%2A%201%7D%20%5Cfrac%20%7Bcm%7D%20%7Bh%7D%20%3D%5C%5C%5Cfrac%20%7B45.72%7D%20%7B24%7D%5Cfrac%20%7Bcm%7D%20%7Bh%7D%20%3D)
![1,905 \frac {cm} {h}](https://tex.z-dn.net/?f=1%2C905%20%5Cfrac%20%7Bcm%7D%20%7Bh%7D)
Answer:

Answer:
Friction does not oppose motion, it oppose relative motion.
Explanation:
static friction opposes relative motion
The object in the lower orbit will move faster in its orbit, and will have a shorter orbital period. None of that depends on their masses either.
