Calculate the work required to move a planet’s satellite of mass 1820 kg from a circular orbit of radius 2r to one of radius 3r, where 7.37×106 m is the radius of the planet. the mass of the planet is 7.51 × 1024 kg. answer in units of j.

The work required to move a planet's satellite is W = 2854.61 J

Explanation:

Given data,

The mass of the satellite, m = 1820 kg

The radius of the circular orbit, r =  2R

The radius of the planet, r = 5.37 x 10⁶ m

The mass of the planet, M = 7.5 x 10²⁴ kg

The formula for work done from the 2R to 3R is,

                            W =

                            W = GMm/3R - GMm/2R

                             W = (-0.17)GMm/R  J

The negative sign indicates that the energy stored in the satellite as the potential energy.

Substituting the values

                              W = (-0.17) 6.673 x 10⁻¹¹ X 7.51 x 10²⁴ X 1820 / (7.37 x 10⁶)²

                                  = -2854.61 J

Hence, the work required to move a planet's satellite is W = 2854.61 J

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
