A21.6-kg cube made from aluminum is at its melting temperature of 660℃. if you were to add 8000 kj worth of energy as heat, what percent of the block melts? you might need the following: α = 23.0 ✕ 10-6 k-1 , β = 69.0 ✕ 10-6 k-1 , c = 900 j/kgk, lf = 3.98 ✕ 105 j/kg

Can you match these to the correct definition

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n.m2 . find the energy u1 of the dielectric-filled capacitor.
