In a movie, the heroine saves the day by cutting a wire before the time runs out on a timer. how did she change the circuit? a. she changed a short circuit to an open circuit. b. she changed an open circuit to a closed circuit. c. she changed a closed circuit to an open circuit. d. she changed a closed circuit to a short circuit.

option c

Explanation:

A circuit contains a conducting wire and a voltage source. Current flows through a closed circuit. A circuit is said to be open if there is break in the circuit that is there is a disconnect such that current does not flow.

When the heroine cuts the wire, she actually breaks the circuit which means that she changed the closed circuit to an open circuit.

option c is correct.

where are the vectors ?

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat
