Power<span> may be defined as the rate of doing work or the rate of using energy. It can be calculated by dividing the energy output or the work done over the time period. It is calculate as follows:
P = W / t
P = 600 J / 4 s
P = 150 Watts</span>
Answer:
(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.
Explanation:
When a stars is converted from hydrogen to helium then this is known as proton -proton chain reaction.Due to this reaction the temperature between corona of the sun and photosphere increases.The main reason for increasing the temperature is exothermic reaction.
So the option C is correct.
(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.
Answer:
2 Mg + CO2 → 2 MgO
Explanation:
Magnesium ribbon burns in the presence of oxygen to produce Magnesium Oxide
The answer is Latitude (B)
Pressure is created by the number of collisions that occur between the molecules and the surface of container. If the temperature in the container is increased this will cause the molecules to move faster. ... By increasing the number of collisions, this will increase the pressure in the container.
Ex: A 5% increase in absolute temperature will resultin a 5% increase in the absolute pressure. ... Resultant pressure changes will vary. A useful thumb rule for water is that pressure in a water-solid system will increase about 100 psi for every 1 F increase in temperature.
