In the circuit shown on the right, the rate at which R1 dissipating electrical energy is 20.0W.
(a) Find R1 and R2.
(b) What is the emf of the battery?
(c) Find the current through both R2 and the 10.0-Ω
resistor.
(d) Calculate the total electrical power consumption in all
the resistors and the electrical power delivered by the battery

are there answer choices to this question? this seems like a question where you have options to choose from.

  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
