Answer: The terrestrial planets, Mars, Earth, Venus, and Mercury all have relatively high densities and low gas content, e.g., they are small and rocky. The Jovian (or giant planets), Jupiter, Saturn, Uranus, and Neptune, are very large and have rather low densities, e.g., they are gaseous.

To solve this problem we will use the concepts related to energy conservation. Both potential energy, such as rotational and linear kinetic energy, must be conserved, and the gain in kinetic energy must be proportional to the loss in potential energy and vice versa. This is mathematically
![PE = KE_{lineal} + KE_{rotational}](https://tex.z-dn.net/?f=PE%20%3D%20KE_%7Blineal%7D%20%2B%20KE_%7Brotational%7D)
![mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2](https://tex.z-dn.net/?f=mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%2B%5Cfrac%7B1%7D%7B2%7D%20I%5Comega%5E2)
Where,
m = mass
v = Tangential Velocity
= Angular velocity
I = Moment of Inertia
g = Gravity
Replacing the value of Inertia in a Disk and rearranging to find h, we have
![mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2](https://tex.z-dn.net/?f=mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%2B%5Cfrac%7B1%7D%7B2%7D%20I%5Comega%5E2)
![mgh = \frac{1}{2}mr^2\omega^2 + \frac{1}{2}(\frac{1}{2}mr^2)\omega^2 )](https://tex.z-dn.net/?f=mgh%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmr%5E2%5Comega%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B1%7D%7B2%7Dmr%5E2%29%5Comega%5E2%20%29)
![h = \frac{3}{4} \frac{r^2\omega^2}{g}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cfrac%7Br%5E2%5Comega%5E2%7D%7Bg%7D)
Replacing,
![h = \frac{3}{4} \frac{(1.6)^2 (5.35)^2}{9.8}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cfrac%7B%281.6%29%5E2%20%285.35%29%5E2%7D%7B9.8%7D)
![h = 5.607m](https://tex.z-dn.net/?f=h%20%3D%205.607m)
Therefore the height of the inclined plane is 5.6m
Answer:
True
the reason why I chose tire is because when you put a straw in a cup of water the water refract or bend
Answer: A driver must not drive a vehicle at such a slow speed ... When driving under adverse weather, road or traffic ... before the school bus stops to pick up or let off students
