the LDR is connected in series with a fixed resistor of resistance 10 k ohms and a 4.5 battery. the total resistance at 30 lux is 22000 ohms

32: from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.

i really hope this answer you out! it makes my day people like you and giving back to the community that has me through school! if you could do me a favor, if this you and this is the very best answer and you understand that all of my answers are legit and top notch. mark as brainliest! and have a awesome day!

the rearrangement of particles in a physical change. hope this

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
