Answer: +/- 71,65 Calorías
Explanation: Se deduce que la fuerza aplica para aumentar o disminuir la energía del generador.
+/- x Calorías
X = Equivalente de 300 Joules en calorías
Para poder pasar Joules a calorías.
Hacemos una regla de 3 simple
1 Calorías = 4,18 Julios
0,2392 calorías = 1 Julio
( 1 / 4,18 = 0,2392 calorías)
300 Julios = 71,65 calorías
(0,2392 calorías x 300 julios = +/- 71,65 calorías)
Answer:
Convective zone, chromosphere, corona
Explanation:
A star like the Sun is divided into different layers according to pressure, density, temperature, and the mechanics of energy transport (in the case of the convective zone and radiative zone) for each of those layers.
In stars, there is an equilibrium between two forces, the force of gravity in the inward direction due to their own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in their core, that is known as hydrostatic equilibrium.
That leads to different layers according with the properties described above.
Near the core, in the Sun, there is a radiative zone since radiation is the best mechanism of energy transport in this area. Then, in the next layer, it can be found that convection becomes a more efficient way of energy transport that radiation due to the fact that the inner part of the convection zone is at a greater temperature than the outer one.
Finally, there is the atmosphere of the Sun (chromosphere, photosphere, and corona).
Key terms:
Convection: Transport of energy due to different in density and temperature of a material (liquid, gas).
Answer:
3%
Explanation:
The total energy ingested is 3000J and of those 3000J, 100J are used for growth and reproduction, this is the part of production in the porcupine, since the other 800J and 2100J are used for internal processes of the porcupine.
Therefore the production efficiency is 100J of the 3000J, let's find out how much it is in percentage:
⇒0.033=3.3% ≈ 3%
The correct option es 3% of production efficiency.
Answer:
the cell is the smallest unit
