Avan traveling down a slope with a uniform acceleration of 2.15 meters/second2 attains a speed of 20.00 meters/second after 7.00 seconds. what is the initial velocity of the van?
a. 0.00 meters/second
b. 3.65 meters/second
c. 4.95 meters/second
d. 35.05 meters/second
e. 120.75 meters/second

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.
