2. ¿Cuál es la longitud de un riel de hierro de 50m a 40°C, si desciende la temperatura a 6°C?. ¿Cuánto se contrajo?​

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

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
