An astronaut leaves the International Space Station (ISS) on a tethered line. Although ISS and Earth exert gravitational force on the astronaut, why does she appear to be weightless?
A) Earth only exerts gravitational force on objects at its surface.
B) The mass of the astronaut is insufficient to be affected by gravity.
C) Earth and ISS cancel each other's gravitational force on the astronaut.
D) The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut.

we need answer choices

a coal burning power plant

  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

it would be c. predictability
