When the magnet falls toward the copper block, the changing flux in the copper creates eddy currents that oppose the change in flux. the resulting braking force between the magnet and the copper block always opposes the motion of the magnet, slowing it as it falls. the rate of the fall produces a rate of flux change sufficient to produce a current that provides the braking force. if the copper is cooled with liquid nitrogen, the resistivity of the copper drops dramatically. how will this affect the speed at which the magnet falls toward the copper? a) the magnet will fall at the same speed. b) the magnet will fall more rapidly. c) the magnet will fall more slowly.

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

ill do it for 100, also this isnt 80 its 40

  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
