Asatellite is orbiting earth with a distance r = 2rearth from earth's center. if the satellite is moved to a distance r = 4rearth (twice as far away), its potential energy would be what is was before.

Half

Explanation:

Given that:

Now, if the satellite is moved to a distance

We  have the mathematical expression for the potential energy fue to gravitational field as:

...................(1)

where:

M = mass of earth

m = mass of satellite

R = radial distance of satellite

Now from eq. (1) initially we have:

after the satellite is moved, we have:

which is half of the initial condition.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
