The scientific discipline of astrobiology is a. one of the oldest branches of science b. a relatively young branch of science c. a similar age to other fundamental disciplines like physics and chemistry d. a hypothetical branch of science which has yet to be established

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
