Answer:
0 J
Explanation:
The mass is not moving, therefore the kinetic energy is 0.
(I had this same question and the answer is 0)
Answer:
I am pretty sure its the second one but I could be wrong sorry if I am.
Explanation:
:D
Answer:
I am not 100% sure but i think its because it has moving parts
Explanation:
pls let me know if i was wrong or right in the comments below
hope this helps
<em>Answer:</em>
<em>When </em><em>a </em><em>body </em><em>is </em><em>moving </em><em>on </em><em>a </em><em>circle </em><em>it </em><em>is </em><em>accelerating </em><em>because </em><em>centripetal </em><em>acceleration</em><em> </em><em>is </em><em>always </em><em>acting </em><em>on </em><em>it </em><em>towards </em><em>the </em><em>center.</em>
<em>Please </em><em>see</em><em> the</em><em> attached</em><em> picture</em><em>.</em><em>.</em><em>.</em>
<em>From </em><em>the </em><em>above </em><em>diagram,</em><em>we </em><em>can </em><em>say </em><em>the </em><em>acceleration</em><em> </em><em>is </em><em>always </em><em>acting </em><em>on </em><em>the </em><em>body </em><em>when </em><em>it </em><em>moves </em><em>in </em><em>a </em><em>circle.</em>
<em>Hope </em><em>this </em><em>helps.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>

Answer:
The ratio is ![R_c:R_e = 4 : 1](https://tex.z-dn.net/?f=R_c%3AR_e%20%3D%204%20%3A%201)
Explanation:
From the question we are told that
The period of the satellite is ![T_c = 8 \ years](https://tex.z-dn.net/?f=T_c%20%3D%20%208%20%5C%20%20years)
Generally the period of earth around the sun is ![T_e = 1 \ year](https://tex.z-dn.net/?f=T_e%20%3D%20%201%20%5C%20%20year)
Generally from Kepler's third law , which is mathematically represented as
![\frac{T_c ^2}{T_e^2} = \frac{R_c^3}{R_e^3}](https://tex.z-dn.net/?f=%5Cfrac%7BT_c%20%5E2%7D%7BT_e%5E2%7D%20%20%3D%20%20%5Cfrac%7BR_c%5E3%7D%7BR_e%5E3%7D)
Here
is the radius of the orbit which the satellite rotate around the sun
is the radius of the orbit which the earth rotate around the sun
=> ![\frac{R_c^3}{R_e^3} = [\frac{8}{1} ]^2](https://tex.z-dn.net/?f=%5Cfrac%7BR_c%5E3%7D%7BR_e%5E3%7D%20%20%3D%20%5B%5Cfrac%7B8%7D%7B1%7D%20%5D%5E2)
=>
=>
=> ![R_c:R_e = 4 : 1](https://tex.z-dn.net/?f=R_c%3AR_e%20%3D%204%20%3A%201)
