Answer:
C. crust, mantle, core
Explanation:
density increases as you travel from the crust to the inner core
the crust is on top
next is the mantle
and then the core
Answer:
The acceleration is ![11.1g\ m/s^2](https://tex.z-dn.net/?f=11.1g%5C%20m%2Fs%5E2)
Explanation:
Given that,
Speed ![v= 6.50\ km/s=6.5\times10^{-3}\ m/s](https://tex.z-dn.net/?f=v%3D%206.50%5C%20km%2Fs%3D6.5%5Ctimes10%5E%7B-3%7D%5C%20m%2Fs)
Time t = 60.0 sec
We need to calculate the acceleration
Using formula off acceleration
![a = \dfrac{\Delta v}{t}](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7B%5CDelta%20v%7D%7Bt%7D)
![a=\dfrac{v_{f}-v_{i}}{t}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv_%7Bf%7D-v_%7Bi%7D%7D%7Bt%7D)
We know that,
Missile goes from rest
So, Initial velocity =0
Put the value into the formula
![a =\dfrac{6.50\times10^{3}}{60.0}](https://tex.z-dn.net/?f=a%20%3D%5Cdfrac%7B6.50%5Ctimes10%5E%7B3%7D%7D%7B60.0%7D)
![a=108.33\ m/s^2](https://tex.z-dn.net/?f=a%3D108.33%5C%20m%2Fs%5E2)
On right hand side multiplying and dividing by g = 9.8m/s²
![a=108.33\times\dfrac{g}{g}](https://tex.z-dn.net/?f=a%3D108.33%5Ctimes%5Cdfrac%7Bg%7D%7Bg%7D)
Put the value of g
![a = \dfrac{108.33}{9.8}g\ m/s^2](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7B108.33%7D%7B9.8%7Dg%5C%20m%2Fs%5E2)
![a = 11.1g\ m/s^2](https://tex.z-dn.net/?f=a%20%3D%2011.1g%5C%20m%2Fs%5E2)
Hence, The acceleration is ![11.1g\ m/s^2](https://tex.z-dn.net/?f=11.1g%5C%20m%2Fs%5E2)
Weight is a force caused by gravity. The weight of an object is the gravitational force between the object and Earth.
Friction made it difficult because an object in motion may not always stay in motion due to the friction caused by its movement. For instance, if you roll a ball down a straight platform, it will not go on forever. The friction of the platform and the ball with eventually slow it down and stop it.
Hope this helps!!
