when you turn a television on, you transfer electrical energy into __. choose all that apply.
a heat energy
b light energy
c elastic potential energy
d sound energy
I would choose a,b,d with a note that heat energy is the only end product of the transfer. The others are USING electrical energy to make the transfer from an electromagnetic wave in space that contains the video and audio signals into light and sound.
sound and light energy
a b d
light
which is it
When you turn a television on, you transfer electrical energy into two forms of energy: light energy and sound energy.
To understand this, let's break it down:
a) Heat energy: Although some electrical energy is converted into heat energy during the operation of a television, it is not the main form of energy being transferred when you turn it on.
b) Light energy: When a television is turned on, electrical energy from the power source is converted into light energy produced by the television screen or panel. This light energy is what allows us to see the images on the screen.
c) Elastic potential energy: Elastic potential energy refers to the energy stored in stretched or compressed materials. In the context of turning on a television, there is no direct conversion of electrical energy into elastic potential energy.
d) Sound energy: When the television is turned on, a portion of the electrical energy is converted into sound energy produced by the speakers. This sound energy allows us to hear the audio accompanying the video on the screen.
In summary, when you turn a television on, you transfer electrical energy into light energy and sound energy.
