Electric Heating systems use electricity as a source of heat.
<u>Explanation:
</u>
Each heater consists of an electric resistor, which the heating element in it. The process involved is Joule Heating. It is the phenomenon in which, passage of electric current produces heat. Heat is generated when the electrons from the current and the positive ions of the conductor start interaction.
The presence of voltage difference makes an electric fields, which in turn accelerates the charges present in the conductors. When they collide with ions of conductor, heat gets generated, and emitted out, which we use for heating purposes.
Answer:
8.4 m/s
Explanation:
The toy completes 10 circle in 30 seconds. So its frequency of revolution is
The periof of revolution is the reciprocal of the frequency, so
The radius of the circular path is
r = 4.0 m
So the total distance covered by the toy in one circle is the length of the circumference:
And so the average speed is
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.
<h3 /><h3>Velocidad
</h3>
La velocidad es la relación entre la distancia total recorrida y el tiempo total empleado. Está dado por:
Velocidad = distancia/tiempo
Para 10m de altura:
- Velocidad = 10 m/1.42 s = 7.04 m/s
Para 3m de altura:
- Velocidad = 3 m/0.78 s = 3.84 m/s
Para 1m de altura:
- Velocidad = 1 m/0.44 s = 2.27 m/s
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.
