Reemplazamos en la ecuacion de energia cinetica.
Answer: Option (b) is the correct answer.
Explanation:
Metals are malleable and ductile, that means, metals can be beaten into thin sheets and they can be drawn into thin wires.
While showing the property of malleability and ductility, the bonds between metals did not break as there is only change in the shape of metal.
Thus, we can conclude that out of the given options, in metals, the properties of malleability and ductility are explained by the fact that metallic atoms can roll over without breaking their bonds.
Newton's Third Law of Motion states, for every action there is an equal and opposite reaction. So if this person kicks the door with a force of 32.0N, then the door kicks back with a force of 32.0N, but instead it is in the opposite direction, so it would be -32.0N.
Answer:
option B
Explanation:
The correct answer is option B
By adding insulation to ceiling we can save about 2,000 kilowatt-hours/year.
Insulation is the process of maintains the temperature of the room. Insulation of the ceiling helps in extreme winter and summer.
Insulation is also used to reduce the noise pollution inside the house and Insulation can be used to save energy.
As the usage of the heater in winter and ACs in summer can be reduced.
