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.

A puppy weighing 3 kilograms races through the dog park. If she slows from a speed of 2 meters/second to 1 meter/second, what wi

aliya0001 [1]

Ans: Thus, the kinetic energy change = 4.5 J

The mass of puppy = 3kg

Kinetic energy initial = $\frac{1}{2} mv^{2}$
= $\frac{1}{2}*3*4 = 6 kg-m/s2$

Kinetic energy final = $\frac{1}{2} mv^{2} = \frac{1}{2}*3*1 = 1.5 kg-m/s2$

Thus, the kinetic energy change = 4.5 J
