The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
Independent variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny. Dependent variable: This is the one that you're measuring. In this case, it's how many drops you can get onto a penny without the water spilling off. Control variable: These are things that you keep the same throughout all of the experiments to make sure that your results are actually due to the changes in the independent variable, not some other random change you made. You used the same penny and dropper.
The penny's state of corrosion.
There aren't a definite amount of drops in a volume. there are a few ways to control the size of a drop but it's not reproducible.
By adjusting an electric field.
There are 295.74 drops in 0.5 fluid ounces.
Idle Air Control Valve.
One application of feed back control is where the speed of a motor has to be maintained at a certain RPM and the load it drives is variable. Feedback from the load tells the VFD (Variable Frequency Drive) motor controller what to do. As the load drags the motor speed down the feedback unit sends a electrical impulse to the VFD to increases the speed of the motor. As the load drops off the feedback unit sends a electrical impulse to the VFD to decreases the speed of the motor. These interactions keep the motor RPM at a constant speed. This is a very simplified version of what happens.
In armature speed control, speed can be varied only below the rated speed. Also in it voltage drops will be high.
Missing a birth control pill can result in breakthrough bleeding. As the hormone level in your body drops, bleeding can occur.
It depends. You might imagine situations in which you would need to add oil to a mechanism in drops. In such a situation you would not add 3.24 drops, you would add, say, 4 or 5 drops. In these situations the amount of oil would be discrete. On the other hand, the measure of the oil in a tank could be given to some considerable degree of precision. It would not be counted. In this case the amount of oil would be (effectively) continuous.
