A brass rod is 2m long at a certain temperature .what is the length for a temperature of 100k. if the linear expansivity of brass is 0.0000018​

a 2,000 calorie based diet.

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

conduct current i mean it makes sense
