Answer:
30Ω
Explanation:
To calculate the equivalent resistance in the circuit, do the following:
Step 1:
10Ω and 20Ω are in series connection. Therefore their equivalent is: 10 + 20 = 30Ω
Step 2:
The equivalent resistance (30Ω) obtained from the above is in parallel connection with 30Ω resistance shown in the diagram above.
Therefore their equivalent is given by:
1/30 + 1/30 = 2/30 = 1/15.
Now invert to obtain the equivalent
Therefore, the equivalent is 15Ω
Step 3:
Determination of the overall equivalent of the resistance of the circuit.
The new equivalent resistance 15Ω obtained above is in series connection with 15Ω resistance in the diagram above.
Therefore their equivalent is given by:
15Ω + 15Ω = 30Ω
Therefore, the equivalent resistance in the circuit is 30Ω
Answer:
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.
Explanation:
Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting
