Question: You leave a 80W light bulb on for 8 hours in the day.
Part I: Express energy through power P and time interval ?t.
Part II: How much energy has been used in joules?
Part III: If the energy used were used to lift a weight of m = 145 kg, write an equation of the height h that the weight can be lifted in terms of P, ?t, and m?
Part IV: Calculate the numerical value of h.
