<h3><u>Answer;</u></h3>

<em>D.) motion energy  </em>

<em>E.) radiant energy</em>

<h3><u>Explanation;</u></h3>
  • <em><u>Energy is the ability to do work. From the law of conservation of energy, energy can not be created nor destroyed by may be transformed from one form to another.</u></em> Instruments or devices which converts energy from one form to another are called transducers.
  • <em><u>Hair dryer is an example of a transducer which converts electrical energy to either thermal or heat energy and also to kinetic energy. </u></em>Electrical energy entering the hair dryer is converted to kinetic energy or motion energy as the small electric motor in the dryer spins a fan blade.
  • Additionally,<em><u> electrical energy is also converted into heat or thermal energy in a grid of wire that heats up.</u></em> The fan pushes air across the hot wires, and hot air blows out the nozzle of the hair dryer.

One circuit contains only an ac generator and a resistor, and the rms current in this circuit is IR. Another circuit contains on
snow_tiger [21]

Answer:

1/3 times.

Explanation:

Let V₀ be the peak voltage .

IR ( rms )  = ( V₀ / √2 R )

R is value of resistance

IC =  ( V₀ ωC / √2  )

( 1 / ωC is reactance of capacitance in ac circuit  )

\frac{I_R}{I_C} =\frac{\frac{V_0}{\sqrt{2}R } }{\frac{V_0\omega C}{\sqrt{2} } }

= \frac{I_R}{I_C} = \frac{1}{\omega C R}

When frequency is tripled angular frequency will also be tripled

hence the ratio \frac{I_R}{I_C} becomes 1/3 times.

How are sublimation and deposition different from each other
yanalaym [24]
There are six distinct changes of phase which happens to different substances at different temperatures. ... Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase. Deposition: the substance changes directly from a gas to a solid without going through the liquid phase.

How much energy is contained in matter what the mass of 1 gram (0.001 kilogram)
kaheart [24]

Classically and Newtonianly, it's the sum of the chemical energy if any,
the electrical energy if any, the thermal energy if any, and the mechanical
energy consisting of potential and kinetic energy if any.

The mechanical energy, consisting of potential and kinetic energy if any, is

           0.001 x [ (acceleration of gravity x height) +  (1/2) (speed)² ] .

But I've got a sneaky hunch that you're not talking about any of these.
You want to know how much [ <em><u>mc</u>² </em>] there is in 1 gram of mass.  No prob.

           E = m c² = (0.001) x (3 x 10⁸)² = <em>9 x 10¹³ joules</em>

That's the energy that a 1,000-watt toaster uses
in  <em>2,852 years</em>  of continuous toasting.
