8miguel needs to use an electric hot plate to heat a beaker of water. as he starts to plug the hot plate into the socket, he notices that the cord is frayed. what would be the best thing for miguel to do? a. wrap the frayed area with electric tape before using it b. notify the teacher and ask for a new hot plate c. wait for the next lab group to be done and then use their hot plate d. use the hot plate as is since it is only needed for a short time

The best answer should be B.

Apparatus in laboratories can be really dangerous, especially the ones which involves electricity.

As a student, he should not just wrap the cord with electric tape, as he might wrap them in a wrong way and possible could hurt himself. So A is not a good answer.

And for C, even though it is a great idea not to use the frayed cord hot plate, but he should also notify the teacher as that hot plate with frayed cord may be passed on and be used for the other students which may pose a risk to them.

And obviously, using the hot plate with frayed cord is super dangerous and he could possibly get electric shock. So D is the incorrect answer.

And it's only left to B, it right to notify the teacher so the teacher can actually either fix it themselves or they wouldn't pass on to other students to use it.
