An AC generator consists of 20 circular loops of wire with an area of 75 cm2 . It has a maximum induced
voltage of 24 V. If its armature rotates at a frequency of 60 Hz, what is the magnitude of the magnetic field,
assuming it is uniform?

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

  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

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
