1. A car travels 15 kilometers in two hours. What is its speed? Solving for:

Formula:

Show work:

Answer w/ units:

first change their units

15km = 15000m

2hrs = 7200secs

now,

speed = distance/timetaken

= 15000/7200

= 2.08 m/s

a) are muscles that have bands.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
