How do you manipulate variables in an experiment? A manipulated variable is the independent variable in an experiment. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one manipulated variable at a […]

Is a 0 GPA possible? Is it possible to have a negative GPA? No. The lowest grade you can get, an F, is a 0. However, while it theoretically is possible to have a GPA of 0, it is impossible to graduate with a 0 GPA as an F means that you don’t receive credit […]

What direction does a wave move? A wave is transporting energy from left to right. The particles of the medium are moving back and forth in a leftward and rightward direction. When a guitar string is plucked what direction does the wave travel? In a longitudinal wave, particles of the medium vibrate back and forth […]

What is the purpose of an egg drop experiment? Purpose: To explore concepts of momentum and collision by developing a container to lessen the force of impact when an egg is dropped from a high place. What can you do to keep a falling egg from breaking in impulse terms? Lead a discussion and analyze […]

What happens when distilled water enters the bloodstream? Distilled water doesn’t have any solutes. Distilled water is going to dilute the plasma so as the water flowing into the blood vessel then were starting see the plasma concentration drop. Blood cells take up water, enlarge finally they’re going to burst open. What type of environment […]
