Answer:
The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy. ... Many quantum mechanical properties are washed out by the thermal agitation that occurs in materials.
Answer:10 A
Explanation:
According to the KCL (Kirchhoff's current laws)
Explanation:
Below is an attachment containing the solution.
The average speed of an equatorial point is given by the ratio between the distance covered during one complete rotation (therefore, the circumference of Jupiter at the equator) and the time to complete one rotation:
![v= \frac{S}{t}](https://tex.z-dn.net/?f=v%3D%20%5Cfrac%7BS%7D%7Bt%7D%20)
where S is the circumference and t the time.
The radius of Jupiter is
![r=7.1 \cdot 10^4 km = 7.1 \cdot 10^7 m](https://tex.z-dn.net/?f=r%3D7.1%20%5Ccdot%2010%5E4%20km%20%3D%207.1%20%5Ccdot%2010%5E7%20m)
so the circumference at the equator is:
![p=2 \pi r = 2 \pi (7.1 \cdot 10^7 m)=4.46 \cdot 10^8 m](https://tex.z-dn.net/?f=p%3D2%20%5Cpi%20r%20%3D%202%20%5Cpi%20%287.1%20%5Ccdot%2010%5E7%20m%29%3D4.46%20%5Ccdot%2010%5E8%20m)
While the time to complete one rotation is (in seconds)
![t=9h 50 min=590 min = 35400 s](https://tex.z-dn.net/?f=t%3D9h%2050%20min%3D590%20min%20%3D%2035400%20s)
Therefore the average speed of a point at the equator is
