A wagon with a weight of 300 N is accelerated across a level surface at 0.5 m/s2. What net force acts on the wagon? 9.0 N
15 N
150 N
610 N

F = 15.29[m/s²].

Explanation:

To solve this problem we must use Newton's second law which tells us that the force is equal to the product of mass by acceleration.

ΣF =m*a

where:

m = mass [kg]

a = acceleration = 0.5 [m/s²]

Therefore we must find first the mass.

Now replacing in Newton's second law.

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.

b.
