Can someone me out with this

also idk why it’s upside down i can’t fix it

What is the difference between electrically neutral objects and electrically charged objects

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

(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?
