Indiana Jones is being chased over the rooftops of Marseilles by some random villain. He looks ahead and sees that there is a 7 meter gap between this rooftop, which is 25 meters above the ground, and the next, which is 19 meters above the ground. He gathers up all his strength and runs and leaps from the higher roof to the lower. How fast must he run so he doesn't go plummeting into the street below? * 5 points

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.
