Answer:
8 minutes sooner
Explanation:
Average speed of snail= 4cm/min
Distance to be covered = 160cm
Time taken for the journey = distance/speed
Time taken for the journey = 160/4
Time taken for the journey = 40 min
If it crawed an average speed of 5cm/min
Distance = 160 cm
Time for the journey = distance/speed
Time for the journey = 160/5
Time for the journey = 32 min
Its going to take the snail 40 min - 32 min to Kno how sooner it will taje it if the average speed is 5cm/min
40 min - 32 min = 8 min
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.
