<span>The answer is B. It can be converted from high to low voltage and vice versa using transformers. That is why high voltages (tens or hundreds of kilovolts) is used to efficiently transfer electricity for large distances and then converted to 110-240V.
The answer can also be derived by elimination. [A] is not right because battery provides only Direct Current (DC). [C] is not right because high voltages are used for AC (from 110V to hundreds of kilovolts). [D] is not right because as the name Alternating Current suggests, the current is alternating in its direction. [E] is not right because DC was the first type of current invented.</span>
Answer:
Current in the circuit(I) = 0.5 ampere
Explanation:
Given:
Number of resistors = 2 (10 ohm each)
Series of resistors
EMF = 10 volt
Find:
Current in the circuit(I)
Computation:
Total resistance in series = R1 + R2
Total resistance in series = 10 + 10
Total resistance in series = 20 ohm
Current in the circuit(I) = EMF / Total resistance in series
Current in the circuit(I) = 10 / 20
Current in the circuit(I) = 0.5 ampere
If an air parcel is given a small push upward and it falls back to its original position, the atmosphere is said to be Stable.
A Stable atmospheric condition is a state where a body thrown like an parcel tends to return to its original position where it was present earlier even after being disturbed externally.
Stable conditions tends to oppose the forces that lead to the displacement of the object from original position.
When a parcel is given a small push upward and it falls back to its original position in air. This shows Stability in the atmosphere which bring back the sir parcel where it was present initially.
A body under the action of gravity in case of stable equilibrium conditions shows returning back of the body after sometime on reaching a certain height.
