C)If two moving objects collide, then they will move away from each other in opposite directions.
D)If a moving object hits another object, then the second object will start moving.
3.Two metal balls with the same mass hang so that they are touching each other. The ball on the left is pulled to the side and released. What will happen when it swings back and hits the ball on the right?(1 point)
A)The ball on the left will stop, and the ball on the right will remain still.
B)The ball on the right will swing to the right.
C)Both balls will swing to the left.
D)Both balls will swing to the right.

4.How do bumper cars at an amusement park demonstrate Newton’s third law?(1 point)

A)If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with the same force.
B)If two bumper cars collide with a certain force, then one car will transfer its force to the other car and they will move together in the same direction.
C)If two bumper cars collide with a certain force, then they will move away from each other in opposite directions with a stronger force.
D)If two bumper cars collide with a certain force, then one car will transfer its force to the other car and they will move away from each other in opposite directions.
5.An octopus propels itself through the water by ejecting water through a funnel in its body. How does this demonstrate Newton’s third law?(1 point)
A)When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the opposite direction.
B)When the octopus ejects the water out, the water acts with an equal force on the octopus in the same direction.
C)When the octopus ejects the water out, the water acts with an equal force on the surrounding water in the same direction.
D)When the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction.

Question 1 what is amperage? is the rate of doing work. is the rate of flow of protons in electric current. represents the amount of pressure behind electron flow. is the rate of flow of electrons in electric current. 2 points question 2 what is voltage? is the rate of doing power. represents the amount of pressure behind electron flow. is the rate of doing work. is the rate of flow of electrons in electric current. 2 points question 3 what is power? is the rate of flow of protons in electric current. is the rate of flow of electrons in electric current. is the rate of doing work. represents the amount of pressure behind electron flow. 2 points question 4 if we multiply volts times amps we get what? power circuit work current 2 points question 5 what are two ways alternating currents are similiar? in both ac and dc electrons flow in the same pattern. in both ac and dc, the flow of electrons changes directions back and forth. both ac and dc are only possible in certain materials with atoms that will allow electron flow. both ac and dc involve the flow of electrons. 4 points question 6 how does the flow of electrons flow in an alternating current? the flow of electrons is always slower in an alternating current than within a direct current. the flow of electrons is not constant and forward; it changes direction back and forth. electrons flow from from a higher affinity to that of a lower affinity. electron flow is constant and only in a forward direction. 2 points question 7 what is the flow like in a direct current? the flow of electrons is not constant and forward; it changes direction back and forth. the flow of electrons is constant and only in a forward direction. the flow of electrons go from a higher affinity to a lower affinity. the flow of electrons are always faster in a direct current. 2 points question 8 how is an electric current able to flow? electrons flow from the higher affinity to lower affinity and electrical current is generated. protons flow from the higher affinity to lower affinity and electrical current is generated. the movement of protons from one atom to another leads to an electric charge. the movement of electrons from one atom to another atom in a line results in a flow of electric current. 2 points question 9 how do electrons move from the two different types of metal in a battery? protons flow from the metal with the lower affinity to the metal with higher affinity and electrical current is generated. electrons flow from the metal with the lower affinity to the metal with higher affinity and electrical current is generated. electrons flow from the metal with the higher affinity to the metal with lower affinity and electrical current is generated. protons flow from the metal with the higher affinity to the metal with lower affinity and electrical current is generated.
