Answer:
The approximate absolute brightness is 10,000 and the temperature is 22,000 of the main sequence star.
The approximate absolute brightness is 100-1,000 and the temperature of the giant star is 22,000.
The answer is supergiants.
Explanation:
Hope u do good :)
Answer:
100 micro-ampere
Explanation:
The sensitivity of an ammeter is the current required for the ammeter to reach its maximum reading or to cause maximum deflection of the ammeter.
As the relative amount of current required to cause maximum deflection of an ammeter is lesser, the sensitivity of the ammeter is said to be higher or the ammeter is said to be more sensitive
Therefore, given that the maximum reading on the given microammeter is 100 μA, the current required to cause the maximum deflection an thus the sensitivity of the ammeter is 100 micro-ampere.
Answer:
The engine would be warm to touch, and the exhaust gases would be at ambient temperature. The engine would not vibrate nor make any noise. None of the fuel entering the engine would go unused.
Explanation:
In this ideal engine, none of these events would happen due to the nature of the efficiency.
We can define efficiency as the ratio between the used energy and the potential generable energy in the fuel.
n=W, total/(E, available).
However, in real engines the energy generated in the combustion of the fuel transforms into heat (which heates the exhost gases, and the engine therefore transfering some of this heat to the environment). Also, there are some mechanical energy loss due to vibrations and sound, which are also energy that comes from the fuel combustion.
1. They are made from metals combined in equal amounts
2. They are good conductors of electricity
3. They are brittle
