@MissLAlbert there's charge but the dead battery no longer has enough energy to get the charge moving

[Wendy Wang @Swang8Wang]

@MissLAlbert it comes from electrons and protons and a object is charged when the number of electrons and protons aren't balanced

[Wendy Wang @Swang8Wang]

@MissLAlbert so you can change the current because I =V/R

[Wendy Wang @Swang8Wang]

@MissLAlbert the electrical potential energy converts to light

[Wendy Wang @Swang8Wang]

@MissLAlbert the electrons come from the batteries

[Wendy Wang @Swang8Wang]

@MissLAlbert If it's the right pitch then it's resonance if not then it isn't resonance

[Wendy Wang @Swang8Wang]

@MissLAlbert They change the frequency to change the pitch so they can play a different note

[Wendy Wang @Swang8Wang]

@MissLAlbert transversal because we can hear the change in pitch

[Wendy Wang @Swang8Wang]

@MissLAlbert resonance occurs when the frequency is close to the natural frequency. Creates standing wave

[Wendy Wang @Swang8Wang]

@MissLAlbert fix ends: flips when it comes back. Open at one end: on same side when it comes back. Open both ends: wave doesn't come back.

[Wendy Wang @Swang8Wang]

@MissLAlbert a standing wave looks like it's not moving but it has frequencies

[Wendy Wang @Swang8Wang]

@MissLAlbert apply a greater force and increase the initial height

[Wendy Wang @Swang8Wang]

@MissLAlbert Two waves somehow pass through each other

[Wendy Wang @Swang8Wang]

@MissLAlbert yes and I think they transfer both matter and energy

[Wendy Wang @Swang8Wang]

@MissLAlbert the torque is not evenly applied on the tic tac because of the way it shaped

[Wendy Wang @Swang8Wang]

@MissLAlbert The top half of the wheel is rotating but the bottom half is not because the bottom half has no velocity for a instant

[Wendy Wang @Swang8Wang]

@MissLAlbert the ball bc it has less inertia and less friction

[Wendy Wang @Swang8Wang]

@MissLAlbert the plane in both cases.if they have the same mass and the plane is the biggest so the mass are distributed more on the outside

[Wendy Wang @Swang8Wang]

@MissLAlbert Rotational inertia increases when mass and radius increase

[Wendy Wang @Swang8Wang]

@MissLAlbert small mass, smooth surface, small radius, circular shape
