Kepler's first law states that a. the square of the orbital period of a planet is directly proportional to the cube of the semimajor axis of its orbit. b. the square of the orbital period of a planet is indirectly proportional to the cube of the semimajor axis of its orbit. c. planetary orbits are elliptical in shape. d. planets remain at a constant distance from the sun.

Kepler's first law states that planetary orbits are elliptical in shape. (C)

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

  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
