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.
Answer: it turns into energy
Explanation: In a nuclear fusion reaction, two reactants combine, and form new products. But the mass of the products is less than total mass of the reactants. This is because a part of mass is lost as energy. This can be seen in an example shown below. You can see that mass is of the products is less than that of the reactants.
Hope This Helps :)
Average acceleration = (change in speed) / (time for the change)
In this case . . .
Average acceleration = (speed at the end - speed at the beginning)/10sec.
We can't be any more specific without knowing the difference
between the beginning speed and the ending speed.
Should the question say “what is the weight of the truck”? :)
I can then answer it. There is no information to find the weight of the boat ;)
