A 1,000-kg car traveling at 30 m/s skids 10 m before it stops. What magnitude of force is the frictional force on the car? (A) 1.5 x 103 N (B) 3.0 x 103 N (C) 4.5 x 103 N (D) 4.5 x 104 N​

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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
