A truck travels 2345 meters. How many kilometers is this? **1 kilometer = 1000 meters** *

2.345 km

Explanation:

Step 1: Find conversion

1 km = 1000m

Step 2: Set up dimensional analysis

Step 3: Multiply and cancel out units

meters and meters cancel out.

We are left with km, which is what we want.

2345/1000 (base 10 system rules) = 2.345 km

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
