At t = 0, the current through a 65.0 mH inductor is 52.0 mA and is increasing at the rate of 100 mA/s. What is the initial energy stored in the inductor? ________8.788e-5____________ J How long does it take for the energy to increase by a factor of 10 from the initial value? _________________ s Help for the second part please, if you could show an equation that would be great! Thanks!

1. (40 pts) A spherical thermocouple (TC) is inserted into a duct to measure temperature of flowing air. The duct and TC were initially cold (27°C) and are exposed to sudden flow of hot air (77°C) at 3 m/s. a) (15 pts) What is the convective heat transfer coefficient on the TC surface? b) (15 pts) How long does it take for the TC to read the gas temperature...
please help!! thank you

please someone help me with question 2. thank you
2. For a second-order reaction where Alaal with 0.20 mol/L of A. Baal, the half life is 10.22 min starting A. What is the rate constant? B. How long will it take for 80.0% of a solution of 0.20 M A to react? C. What is the half-life of the reaction when starting with 0.20 MA? Rate = k [A]. – [A]e = kt Rate = k[A] Rate = k[A] k...
can anybody help me why this is wrong
..thank you..step by step please..
