Answer:

B: Electrical - Heat

C: Electrical - kinetic

Explanation:

When the hair dryer is plugged to electric supply, electrical energy is converted into heat. When this electricity is circulated through a resistor, heat is now created in the form of losses which make the air around the resistors to be heated.

After that process, this electricity turns into kinetic energy because it forms Electric energy which moves the fan in order to create a flow with the air that's heated.

Charge is distributed uniformly along a long straight wire. the electric field 2 cm from the wire is 20 n/c. the electric field
Serjik [45]

The electric field 4cm from the wire is

É = 10nc { }^{ - 1}

Given:

charge is distributed uniformly along a long straight wire.

electric field 2cm from the wire is 20n/c

To find:

electric field 4cm from the wire

what is electric field?

Electric field is the region around charge particle or charged body in which if another charge is placed it experiences electrostatic force.An electric field is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.

E   ∝ \frac{1}{r}

\frac{E}{É}  =  \frac{r2}{r1}

\frac{20}{ É }  =  \frac{4}{2}

É =  \frac{40}{4}

É = 10nc {}^{ - 1}

thus the electric field 4cm from the wire is

É = 10nc { }^{ - 1}
