Are slow oxidative fibers fatigue resistant?
Are slow oxidative fibers fatigue resistant? The three types of muscle fibers are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). Slow oxidative fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. Which type of fiber is best if you need a quick burst of […]
What is the difference between dependent and independent variables?
What is the difference between dependent and independent variables? You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the […]

What are inductors and capacitors used for?
What are inductors and capacitors used for? Capacitors and inductors are electronic components that can store energy supplied by a voltage source. A capacitor stores energy in an electric field; an inductor stores energy in a magnetic field. How are capacitors and inductors used together? Inductors that share the magnetic path are combined together and […]
What does null hypothesis mean?
What does null hypothesis mean? The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena. What is the null hypothesis for at test? The null hypothesis remains the same for each […]

What is the distance a screw thread advances axially in one turn called? Lead What are the different types of screw threads? Clamp screws come in many forms. There are Standard threads, ACME threads, Buttress threads, and Square threads. Each of these threads may be used in clamps and vises for different reasons. What are […]
Can you hear normally with a cochlear implant?
Can you hear normally with a cochlear implant? The implant doesn’t make you hear normally again, but it can help you with sounds.
