Un asensor de masa 500 kg , con cuatro personas a bordo , cada una con una masa de 75 kg , asciende con una altura de 28 metros Calcula la energia potencial que adquiere el asensor

 U = 2,195 10⁵ J

Explanation:

The potential energy is

      U = m g and

in this case each person has a mass of 75 kg and the elevator has a mass of 500 kg, the total mass is

 m_total = m_elevator + 4 m_person

      m_total = 500 + 4 75

      m_toal = 800 kg

let's calculate

       U = 800 9.8 28

       U = 2,195 10⁵ J

coil wire, increase current, put iron inside the coil

this means that the temperature of both substances will be equal
