An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 2010 × 103 seconds (about 23 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 225.0 × 106 m and the planet has a radius of 3.80 × 106 m, calculate the moon's radial acceleration a c .

Radial acceleration of moon is

Explanation:

Given :

Time period sec

Distance from center of moon to planet m

From the equation of radial acceleration,

Where

So  

Now moon's radial acceleration,

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
