@MissLAlbert A resistor would take away the electrons in both of them while trapping #3rdperiodphys #BR87

[David Balaban @EasyMoneyDavid1]

@MissLAlbert charge comes from electric current or electrons and you can add or subtract electrons #3rdperiodphys #BR86

[David Balaban @EasyMoneyDavid1]

@MissLAlbert They create different voltage since they resist the current #3rdperiodphys #BR85

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The electrons go from from one side to another through the filament they are still there without the outlet #3rdperiodphys#BR84

[David Balaban @EasyMoneyDavid1]

@MissLAlbert They come from the electric current, the outlet provides a port for the electrons to move from - to + ends #3rdperiodphys #BR83

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The neutral object will not move anywhere since the opposite charges will balance #3rdperiodphys #BR82

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The fundamental frequencies would be different by a factor of 2 #3rdperiodphys #BR715

[David Balaban @EasyMoneyDavid1]

@MissLAlbert for open open you add it to itself and for closed you double it #3rdperiodphys #BR714

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The frequency should go up or down based on how you add wavelengths, not 1/2 #3rdperiodphys #BR714

[David Balaban @EasyMoneyDavid1]

@MissLAlbert By changing the tension in the string the velocity of the waves changes #3rdperiodphys #BR712

[David Balaban @EasyMoneyDavid1]

@MissLAlbert sound is probably a simple harmonic that is open on one end and fixed since it looks like a sin #3rdperiodphys #BR711

[David Balaban @EasyMoneyDavid1]

@MissLAlbert Resonance is when the wave repeats itself and you know when the wave looks the same just adds 1/2 #3rdperiodphys #BR79

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The wave is just half circles and with open ends it looks similar the smallest is a half circle #3rdperiodphys #BR78

[David Balaban @EasyMoneyDavid1]

@MissLAlbert Standing Wave is if the speed doesn't change so the frequency must be equal to the source #3rdperiodphys #BR77

[David Balaban @EasyMoneyDavid1]

@MissLAlbert When you push the kid you have to extend your hands perfectly horizontal when pushing them #3rdperiodphys #BR76

[David Balaban @EasyMoneyDavid1]

@MissLAlbert nope actually if you increase the frequency this will happen #BR75

[David Balaban @EasyMoneyDavid1]

@MissLAlbert If you decrease the frequency the wavelength will also go down since they are closer and period is smaller #3rdperiodphys #BR75

[David Balaban @EasyMoneyDavid1]

@MissLAlbert The waves actually go through each other when colliding which is weird why they wouldn't bounce off #3rdperiodphys #BR74

[David Balaban @EasyMoneyDavid1]

@MissLAlbert Yes they are simple harmonic motion since they usually do not change their motion and transfer energy #3rdperiodphys #BR73

[David Balaban @EasyMoneyDavid1]

@MissLAlbert In the pendulum lab there was no spring constant but instead there was length which serves same purpose #3rdperiodphys #BR72
