Aplanetâs moon revolves around the planet with a period of 39 earth days in an approximately circular orbit of radius of 4.8ã10^8 m. how fast does the moon move?

v = 895 m/s

Explanation:

Time period is given as 39 Earth Days

now the radius of the orbit is given as

so the total path length is given as

now the speed will be given as

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

it is b. absorbs thermal energy
