Ineed how do forensic scientists determine the time of death? there are timely pieces of evidence that scientists with this task. at the time of death: ~the heart stops ~the skin gets tight and grey in color ~cell start to die (brain 3-7 min; skin up 24 hours) ~the muscles relax ~the bladder and bowels empty and then what? order these changes from first to last.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
