When we say the energy in a system remains "constant" what we really mean is...
1 point
the total amount of energy goes up
the total amount of energy remains the same
the total amount of energy goes down
the speed remains the same
of the following is NOT a form of energy?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

The radius of an atom is closest in size to a
