Answer:
The switch within the closed circuit is opened and it stops the flow of current in a circuit.
Explanation:
- Current is defined as a flow of electrons in a system or a circuit.
- There are two basic things needed for current to flow in a system
- One is the electro-motive force and the other is the complete path for current to flow.
- If a switch in a closed circuit gets opened, it restricts the path of current flow.
- Thus it stops the current to be flowed through the circuit.
Answer:
numerical measurement of how far apart objects or points are.
Explanation:
fusion is when solid changes it's state to liquid
and vaporization is when liquid changes it's state to gas
so the difference between fusion and vaporization is the state
Answer:D
Explanation:
For Rod 1
length,diameter and Tension is L, d and T
for Rod 2 length,diameter and Tension is 2L, 2d and 2T
Change in Length is given by
where P=load
L=length
A=area of cross-section
E=young's Modulus
since both are aluminium rod therefore E is common
Thus extension in both the rods are same
Should be A, i am not absolutely certain but all the other options just sound ridiculous
