Assuming nothing else blocks their view, approximately how far can two people stand from each other in clear atmosphere until they can not longer see each other due to the curvature of the earth ? [take : radius of earth = 6400 km] (assume height of each people is 2m) (1) 10 m (3) 1 km (2) 100 m (4) 10 km

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
