Why do heat engines need to reject energy to environment? Expelling heat lets you get a positive area in your PV curve. This argument doesn’t apply to burning oil, because that’s not a cyclic process. In order to achieve this, the system dumps this extra gained entropy by giving off thermal energy to the cold […]
Is analog or digital better for sending large amounts of data?
Is analog or digital better for sending large amounts of data? Analog signals are composed of continuous waves that can have any values for frequency and amplitude. Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to […]

What are the 6 steps of action potential?
What are the 6 steps of action potential? An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. Hypopolarization is the initial increase of the membrane potential to the value of the threshold potential. What are the 5 steps of an action potential? The action potential can be divided into five phases: the […]
