Mars has a mass of 6.42 1023 kg and a radius of 3.40 106 m. Assume it is a uniform solid sphere. The distance of Mars from the Sun is 2.28 1011 m. (Assume Mars completes a single rotation in 24.6 hours and orbits the Sun once every 687 Earth days.) (a)What is the rotational kinetic energy of Mars on its axis?
J
(b)What is the rotational kinetic energy of Mars in its orbit around the Sun?
J

  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
