Answer:
C. The brightness of the remaining light bulbs will not change
Explanation:
If the battery is assumed ideal, the voltage supplied to each of the remaining two bulbs is still 9 volts. This will drive the same current through the fixed resistance of each bulb both before and after the third bulb is removed.
Answer:
examples of mixture: smoke,fog,sand, potassium nitrate, sulfur and carbon.
examples of compounds: mithane, ammonia,salt and nitrous oxide.
examples of elements: hydrogen , helium, oxygen and neon.
Explanation:
there are more elements
To solve this process it is necessary to consider the concepts related to the relations between pressure and temperature in an adiabatic process.
By definition the relationship between pressure and temperature is given by
Here
P = Pressure
T = Temperature
The ratio of specific heats. For air normally is 1.4.
Our values are given as,
Therefore replacing we have,
Solving for
Therefore the maximum theoretical pressure at the exit is
