The wattage of speaker describes the rate at which energy is converted from electrical energy to sound energy. this is the description of which of these?

energy
eliminate
b) power
c) transformation
d) work

The correct answer is B.

Explanation:

Power is defined as the rate of doing work.

The unit of power is watt. It is defined as one joule per second.

The formula for the power is defined as:

Here, W is the work and t is the time taken.

In the given problem, the wattage of speaker describes the rate at which energy is converted from electrical energy to sound energy.

Therefore, this is the description of Power.

  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
