Well, you need no look further than the word "terrestrial" If you notice the beginning of the word you notice that it consists mostly of the word "terra" Terra by definition is just land. Due to the solid land of these 4 planets, they're called terrestrial planets, the other 4 aren't made of land but of gas which is why they aren't classified as terrestrial planets.
Answer:According to the Equation (2), centripetal force is proportional to the square of the speed for an object of given mass M rotating in a given radius R.
Explanation:The Period T. The time T required for one complete revolution is called the period. For. constant speed. v = 2π r T holds.
Answer:
The order of magnitude of the distance from the sun to Earth is 10⁸ km.
Explanation:
The order of magnitude of the distance from the sun to Earth can be calculated as follows:
![c = \frac{x}{t}](https://tex.z-dn.net/?f=%20c%20%3D%20%5Cfrac%7Bx%7D%7Bt%7D%20)
Where:
c: is the speed of light = 3x10⁸ m/s
t: is the time = 8 min
Hence, the distance is:
![x = c*t = 3 \cdot 10^{8} m/s*8 min*\frac{60 s}{1 min} = 1.44 \cdot 10^{11} m = 1.44 \cdot 10^{8} km](https://tex.z-dn.net/?f=%20x%20%3D%20c%2At%20%3D%203%20%5Ccdot%2010%5E%7B8%7D%20m%2Fs%2A8%20min%2A%5Cfrac%7B60%20s%7D%7B1%20min%7D%20%3D%201.44%20%5Ccdot%2010%5E%7B11%7D%20m%20%3D%201.44%20%5Ccdot%2010%5E%7B8%7D%20km%20)
Therefore, the order of magnitude of the distance from the sun to Earth is 10⁸ km.
I hope it helps you!
