Answer the following question given this paragraph: Two forces may act on an object in the same direction. You can see an example of this in Figure below . After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces alone. In this case, the net force on the couch is 45 newtons to the right, so the couch will move to the right. Q: What is the net force when two forces act in the same direction? Choices: - number of the forces - arguing forces - group of forces - sum of the forces A:
sum of the forces

Answer the following question given this paragraph: If you take a hot shower in a closed bathroom, the mirror is likely to "fog" up. The "fog" consists of tiny droplets of water that form on the cool surface of the mirror. Why does this happen? Some of the hot water from the shower evaporates, so the air in the bathroom contains a lot of water vapor. When the water vapor contacts cooler surfaces, such as the mirror, it cools and loses energy. The cooler water particles no longer have enough energy to overcome the forces of attraction between them. They come together and form droplets of liquid water. Q: What results when the water vapor from a hot shower contacts the cooler surface of a mirror? Choices: - the mirror breaks - mirror brightens - cleaner mirror - foggy mirror A:
**Answer**
foggy mirror
