Construct a circuit consisting of a function generator, a DMM, a ground and an oscilloscope. Set the function generator to output a 1kHz, 10 Vpp sine wave. Display the output on Ch. A of the oscilloscope by connecting the positive terminal of the function generator to the positive terminal of the oscilloscope and the common terminal (not the negative terminal) of the function generator to the negative terminal of the oscilloscope.

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.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

i think the answer is tomato juice? not entirely sure though
