Answer the following question given this paragraph: You might think that actions and reactions would cancel each other out like balanced forces do. Balanced forces, which are also equal and opposite, cancel each other out because they act on the same object. Action and reaction forces, in contrast, act on different objects, so they don't cancel each other out and, in fact, often result in motion. For example, in Figure above , the kangaroo's action acts on the ground, but the ground's reaction acts on the kangaroo. As a result, the kangaroo jumps away from the ground. One of the action-reaction examples in the Figure above does not result in motion. Do you know which one it is?. Q: What kind of equal and opposite forces cancel one another out when they act on the same object? Choices: - solid - exact - combined - balanced A:
(Answer)
balanced

(Q).
Answer the following question given this paragraph: Volcanic eruptions can be non-explosive or explosive depending on the thickness of the magma. Q: What determines whether a volcanic eruption will be explosive or not? Choices: - lava temperature - magma velocity - curve of magma - thickness of magma A:
(A).
thickness of magma
Ques:Answer the following question given this paragraph: When additional water is added to an aqueous solution, the concentration of that solution decreases. This is because the number of moles of the solute does not change, while the volume of the solution increases. We can set up an equality between the moles of the solute before the dilution (1) and the moles of the solute after the dilution (2). Q: When additional water is added to an aqueous solution, what happens to the concentration of that solution? Choices: - doubles - no change - increases - decreases A:

Ans:decreases
Ques: Answer the following question given this paragraph: This equation shows that momentum is directly related to both mass and velocity. An object has greater momentum if it has greater mass, greater velocity, or both. For example, a bowling ball has greater momentum than a softball when both are moving at the same velocity because the bowling ball has greater mass. However, a softball moving at a very high velocity say, 100 miles an hour would have greater momentum than a slow-rolling bowling ball. If an object isn't moving at all, it has no momentum. That's because its velocity is zero, and zero times anything is zero. Q: Momentum is directly related to both mass and? Choices: - mass - intensity - speed - velocity A:
Ans:
velocity
