@MissLAlbert
Got to sleep
Went to downtown with my family and family friends #BR89 #3rdperiodphys

@MissLAlbert a dead battery still have charge but it might be not active, #BR88 #3rdperiodphys

[Sara @saraphysics]

@MissLAlbert decrease the current by trapping the electrons #BR87 #3rdperiodphys

[Sara @saraphysics]

@MissLAlbert Charge doesn't "come" from anything, and to make something charged gain or lose electron #BR86 #3rdperiodphys

[Sara @saraphysics]

You can resist more current, dissapate heat energy as electric current and reduce more flow of energy #BR85 #3rdperiodphys @MissLAlbert

[Sara @saraphysics]

@MissLAlbert the electrical energy is transformed into thermal energy and it losses small amount of electric potential #BR84 #3rdperiodphys

[Sara @saraphysics]

@MissLAlbert The electrons are comes from the battery, the outlet doesn't provide the electons, it moves through it#BR83 #3rdperiodphys

[Sara @saraphysics]

@MissLAlbert also attract because if an object is neutral both the neg object or pos object still attracts to it#BR82 #3rdperiodphys

[Sara @saraphysics]

The water molecule/intermolecular force- more of a electronegative - pos and neg sides attract each other #BR81 #3rdperiodphys @MissLAlbert

The fundamental frequency is different by a factor of 2 #3rdperiodphys #BR715 @MissLAlbert

[Sara @saraphysics]

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

[Sara @saraphysics]

Susie is right since resonance occurs when driving f is close to natural f and triangle if hit at the right pitch #3rdperiodphys

[Sara @saraphysics]

different instruments have different tension (string)which would affect the frequency and the amp of the sound waves #BR712 #3rdperiodphys

[Sara @saraphysics]

I think sound is a transversal wave because one end is open and one end is closed #BR711 #3rdperiodphys

[Sara @saraphysics]

Resonance consists of many small amplitudes add up to a big amplitude, occurs when driving f is close to natural f #BR79 #3rdperiodphys

[Sara @saraphysics]

fixed both is standing wave, fixed one=flip, open=same side > constructive and destructive #BR78 #3rdperiodphys

[Sara @saraphysics]

If wave remains in a constant position,there is more than one frequency this occurs,can have diff frequencies #BR77 #3rdperiodphys

[Sara @saraphysics]

change tension changes period
Changing frequency changes wavelength #3rdperiodphys #BR76

[Sara @saraphysics]

Increase or decrease tension, the period changes.
Changing frequency changes wavelength,#3rdperiodphys #BR75
