The correct option is (D). i.e.<span>When the current is too high, a metal strip in the fuse melts and opens the circuit.
Explanation: </span>The fuse contains a small piece of wire which has very less melting point. As there is huge current flow, the wire heats to the heavy current flow & melts & the circuit is broken.
Hence, it saves the device from the heavy current flow & the device is damage free. breaks the circuit if a fault in an appliance causes too much current flow.
So base on your question about the moving air and its is cycled in order to reach equilibrium the answer of the questions are the following
A. what are the two major characteristic that change when air is heated and cooled?
-temperature and molecular structure/ phase of the matter
<span>B. how does these characteristics change the movement of air?
</span>-if the air has lower temp the possibility that it will become heavier than with the higher
<span>C. what is the name of the cycle that develop during these changes? Air cycle</span>
<span>D. why do the changes you describe in part B provide an example of a cycle? because of its molecular activity will increase</span>
In psychoanalytic therapies, this gives credence and value to an individual's childhood experiences and the unconscious. This would suggest that childhood experiences are highly involve in later life.

Answer:
Explanation:
magnetic field B = (3 i + 8 x 2 j )x 10⁻³ T
= (3 i + 16 j )x 10⁻³ T
L = - i ( unit length of conductor )
Force F = I ( L x B ) , I is current
= 5 [ - i x ( 3i + 16 j ) 10⁻³]
= 5 ( - 16 k ) x 10⁻³
F = - 80 x 10⁻³ k
