Answer:Increase in the entropy of the universe are the result of chemical reactions
Explanation:
The second law tells about the quality of energy such that any isolated system tends to become more disordered. Any natural Process occurring on its own is irreversible and entropy is increasing for that process.
The entropy of the Universe is increasing which is the result of chemical reactions. Any chemical reaction which increases the number of gas molecules will generate more entropy. Entropy in simple meaning is the order of randomness.
Answer:
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
Explanation:
There are two ways to connect electrical circuits, in series and in parallel.
Series circuits have the problem that when one element is damaged, the entire circuit is interrupted and runs out of power.
In parallel circuits, if one element has a problem, it can be eliminated and the rest of the elements continue to work.
In Breaker it is connected in series so that when some maintenance is needed, all the energy can be interrupted simultaneously and if some equipment tries to consume a lot of energy, the circuit prevents this action by interrupting the energy of the entire circuit
Answer: SF6
Explanation: Hexa is a prefix means 6. Sulfur Hexafluoride is expressed in SF6
Answer:
The current through the tube is 73.39A.
Explanation:
The relationship between the resistivity
, the electric field
, and the current density
is given by

This equation can be solved for
to get:

Since the current is 

Now, for the tube of mercury
,
, and the area is
; therefore,


Hence, the current through the mercury tube is 73.39A.
C. The sun is the most massive object in our solar system.
It also has a stronger gravitational pull.
