I need complete work to these correct answers.

7) a) E = 512.84 Joules, E = 1233.92 Joules b) tcoffee = 190.8 hrs, tcup = 3.64 hrs

7) a) What is the energy emitted in 1 minute from a black coffee mug 1which has a radius of 4 cm and height 6 cm and temperamre of W] Fahrenheit. What will the answer be if the coffee mug is at 20C] Fahrenheit? h) Now, assume the mug is completely lled with creamed coffee. Assume both of their temperatures are initially at 200 Fahrenheit and the atmospheric temperature is TO Fahrenheit Hour.r long Will it take each one to reach T1 F ignoring the transfer of heat to each other by conduction?I (Take the density of the coffee to be 1.1 gi'cm3 , its specic heat to he .95 cali'gC and the mass of the cup to be 200 grams and its specic heat to be .4 cali'gC. Also, take the emissivity of the creamed coffee to be .3)
