Suppose the magnetic field in a given region of space is parallel to the Earth's surface, points north, and has a magnitude of 1.80 10-4 T. A metal cable attached to a space station stretches radially outwards 2.50 km. Required:
a. Estimate the potential difference that develops between the ends of the cable if it's traveling eastward around Earth at 7.70 X 10^3
b. Which end of the cable is positive, the lower end or the upper end?

measuring things 1 litre of water

the closer the planet is to the sun, the larger the gravity

  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
