A switch
What are the answers choices
Answer:
from the position of the center of the Sun
Explanation:
As we know that mass of Sun and Jupiter is given as
![M_s = 1.98 \times 10^{30} kg](https://tex.z-dn.net/?f=M_s%20%3D%201.98%20%5Ctimes%2010%5E%7B30%7D%20kg)
![M_j = 1.89 \times 10^{27} kg](https://tex.z-dn.net/?f=M_j%20%3D%201.89%20%5Ctimes%2010%5E%7B27%7D%20kg)
distance between Sun and Jupiter is given as
![r = 7.78 \times 10^{11} m](https://tex.z-dn.net/?f=r%20%3D%207.78%20%5Ctimes%2010%5E%7B11%7D%20m)
now let the position of Sun is origin and position of Jupiter is given at the position same as the distance between them
so we will have
![r_{cm} = \frac{M_s r_1 + M_j r_2}{M_s + M_j}](https://tex.z-dn.net/?f=r_%7Bcm%7D%20%3D%20%5Cfrac%7BM_s%20r_1%20%2B%20M_j%20r_2%7D%7BM_s%20%2B%20M_j%7D)
![r_{cm} = \frac{1.98 \times 10^{30} (0) + (1.89 \times 10^{27})(7.78 \times 10^{11})}{1.98 \times 10^{30} + 1.89 \times 10^{27}}](https://tex.z-dn.net/?f=r_%7Bcm%7D%20%3D%20%5Cfrac%7B1.98%20%5Ctimes%2010%5E%7B30%7D%20%280%29%20%2B%20%281.89%20%5Ctimes%2010%5E%7B27%7D%29%287.78%20%5Ctimes%2010%5E%7B11%7D%29%7D%7B1.98%20%5Ctimes%2010%5E%7B30%7D%20%2B%201.89%20%5Ctimes%2010%5E%7B27%7D%7D)
from the position of the center of the Sun
Answer:C
Explanation: I studied, and C is correct
Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance.
3. Sand has a low specific heat compared to air
