Aspacecraft is in a 400-km by 600-km leo. how long (in minutes) does it take to coast from the perigee to the apogee?

To solve this problem we will use Kepler's third law for which the period is defined as

The perigee altitude is the shortest distance between Earth's surface and Satellite.

The average distance of the perigee and apogee of a satellite can be defined as

Here,

R = Radius of Earth

= Lower orbit

= Higher orbit

Replacing we have,

Time Taken to fly from perigee to apogee equals to half of orbital speed is

Replacing,

Therefore will take around to 47 min and 12.8s to coast from perigee to the apogee.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation

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 .
