What does the atomic mass tell you? The atomic mass tells us the weight of protons and neutrons. How do you know how many electrons there are surrounding the nucleus of a particular atom? Why isn’t the atomic mass always a whole number? Atomic mass is never an integer number for several reasons: The atomic […]

Why is a scale important on a graph?
Why is a scale important on a graph? The distance between two numbers indicates a unit and this unit remains uniform throughout a scale. Thus, a scale plays a crucial part in plotting graphs. Without scales, we won’t be able to infer anything relevant from the graph. A scale on a graph can have any […]
Why does my balloon car not move?
Why does my balloon car not move? Some of the things that slow balloon cars down, that you have to overcome, are their own weight, air resistance, friction, and inefficient use of the air escaping the balloon. Which type of balloon would deflate the fastest? Helium balloons How much does it cost to fill 100 […]

What is the most probable reason why a life jacket helps you float in water?
What is the most probable reason why a life jacket helps you float in water? The trapped air weighs much less than the weight of the water it displaces, so the water pushes up harder than the life jacket pushes down, allowing the life jacket to remain buoyant and float. This buoyancy is strong enough […]
