And observer reviews for identical objects that are traveling at speed close to the speed of light in their legs be used to rank the objects according to their speeds A. No the Lankes of the four objects should be the same regardless of the speed B. Yes the shortest object is traveling the fastest C. Yes the longest object is traveling the fastest D. No the length of each object demands on the frame of reference of the observer

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

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
