Can momentum be lost to friction? Nope. The momentum lost from an object due to friction is momentum gained by the thing the object is rubbing against. How do you know if linear momentum is conserved? The law of conservation of momentum says that the momentum of a closed system is constant in time (conserved). […]
Why do heat engines need to reject energy to environment?
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 […]
